   DETAILED DESCRIPTION OF THE INVENTION 
   A postal envelope form system is disclosed that has both outgoing and return address information printed by an impact printer on both the outgoing and reply envelopes in one pass, utilizes white areas and colors to improve scan and delivery accuracy, and positions delivery point barcode outside an area typically smeared by post office processing equipment. 
   As is well known, the postal service employs automated mail processing systems to facilitate the handling, sorting and delivery of various types of mailers including envelopes. These automated systems employ codes and electronic code reading devices to effect more efficient and accurate mail processing, improve consistency of delivery, lower postal operating costs and increase savings to postal customers. 
   Numerical mail processing codes corresponding to the address delivery point and now ZIP (Zone Improvement Program) codes are commonly used on envelopes. ZIP coded envelopes without other codes are sent through a postal station where the alpha and numerical ZIP codes are electronically scanned by an optical character reader (OCR) and a processing or sorting code, presently a delivery point barcode in the form of a series or pattern of vertical short and tall bars and which corresponds to the individual numerical code, is applied to each envelope. The bar coded envelopes are passed through a barcode reader (BCR) which electronically reads the barcodes, and a barcode sorter (BCS) to automatically sort the envelopes according to their delivery point barcodes or address destinations. 
   Reply envelopes that are mailed inside of originating or outgoing envelopes by senders such as businesses and other organizations are now often preprinted (i.e., before mailing) with barcodes. The barcode for reply envelopes for a given organization can be readily printed by the sender when the reply address and any other matter is printed on each of the reply envelopes, since the reply address and barcode are the same for each such reply envelope. By preprinting the barcode on the reply envelopes, the reply envelopes do not have to be passed through the OCR and encoder to be barcode by the postal service, and this can result in cost savings to both the sender and the postal service. Some organizations are preprinting barcodes on outgoing envelopes so that even further savings can be realized under certain circumstances with pre-bar-coded mail. 
   When the sender preprints the barcode on the reply envelope, another processing or identification code, presently known as a facing identification mark (FIM), can also be preprinted to provide machine detectable codes for the automatic facing and cancellation of reply mail postage, as well as to identify pre-bar-coded reply mail early in the postal processing system. Different FIM marks are presently used for identifying: (1) “business reply mail without barcode, and Penalty Mail or Franked Mail”; (2) “courtesy reply with barcode and affixed stamp”; and (3) “business reply with barcode and Penalty or Franked Mail”. There is a unique FIM mark available for each type of business reply mail described above. Such FIM marks are typically in the form of a series of parallel vertical lines printed by the sender in the upper right portion of the mail piece just left of the indicia or stamp position. 
   The use of outgoing envelopes containing reply envelopes are, however, relatively expensive since two separate and complete envelopes are required, and both envelopes must be printed separately with addresses. 
   Furthermore, self-mailer forms are typically printed on expensive printers. Inexpensive printers generally could not properly print self-mailer forms. These types of printers include narrow carriage impact printers which are known for a relatively weak printer head punch striking force. This weak striking force causes problems in properly imaging information through to the reply envelope and other parts of an envelope form system. 
   Additional problems are associated with the current requirements for today&#39;s postal standard first class business mail with a business reply envelope. These postal requirements include: (1) complete delivery point postal bar coding on all outgoing envelopes; (2) complete delivery point postal bar coding on the business reply envelopes; (3) a scannable face identification mark (FIM) on the business reply envelope; and (4) a minimum of 70% of the mail delivery point bar coding must be scannable in 1998, 1999&#39;s goal is 80%. The Post Office requirements increase in the year 2000, and for years beyond. Specifically, in the year 2000, the scanability of postal bar coding must be at least 90% accurate. 
   Although there are many self-mailer form arrangements, conventional arrangements do not preprint both mail-to (i.e., outgoing) and return address on both the outgoing and reply envelopes. 
   Additionally, conventional self-mailers are not entirely imaged all the way to and including the response envelope, while meeting upcoming postal standards required in the year 2000. 
   Conventional arrangements are not designed for narrow width impact printers while being able to take advantage of all the best postal discounts while imaging complete information on a small format. 
   An arrangement is needed: 
   that accommodates for narrow carriage impact printers having a width no greater than approximately ten inches, 
   that is more accurate in reading postal barcodes, 
   that is bar coded and able to be successfully read after being processed through the post office envelope processing system, 
   that reduces damage caused by normal processing as a result of the post office envelope processing system. 
   There is also a need for a postal envelope form system: 
   that provides complete information to the user and their customer, 
   that addresses health issues associated with the repetitive task of bursting the envelope form system by hand, 
   that weighs no more than one ounce and is within size dimensions established by post office standards. 
   There is a need for preventing contents of text preprinted on sheets contained within an envelope from interfering with image contrast or scanning which causes misreading of envelopes and a loss of best postal discounts. 
   There is a need for preventing misdelivery of mail caused by a large volume of reply mailers all looking the same and being mistakenly delivered to incorrect mailing addresses. 
   There is also a need for a postal envelope form system that is versatile, and addresses the needs of the user and customer, the impact printer limitations and postal requirements of today and the foreseeable future. 
   The disclosed postal envelope form system may include an outgoing envelope and a reply envelope contained within the outgoing envelope, wherein the envelopes each have a mail-to address and a return address preprinted thereon. 
   The outgoing envelope may include a flap enclosure and a tab opening means for easily opening the flap enclosure, wherein the tab opening means is located at a bottom of the outgoing envelope thereby allowing the return address to be located at a top of the outgoing envelope and the customer return address to be located at a top of the reply envelope. This aspect allows the return addresses to be positioned at an uppermost portion of the envelope to free up valuable space which is used for including complete information on each of two portions of a statement. 
   The outgoing and the reply envelopes may each have delivery point barcodes which identify the intended location for delivering the envelopes, and the reply envelope may include a facing identification mark. These aspects allow the postal envelope form system to qualify for better postal discounts. 
   The sheets may have a front face and a right side edge, and may be fixed together at the right side edge to strengthen the postal envelope form system at a location where postal processing equipment engages the postal envelope form system during processing. 
   A top portion of the mail-to address area may be positioned relative to postal equipment that contacts the envelopes to feed the envelopes through a postal envelope processing system such that the delivery point barcode is left substantially un-contacted to thereby reduce smearing of the delivery point barcode. 
   The postal envelope form system with sheets may include a twelve-and-a-half pound selectively carbonized bond original sheet positioned on top of, a sixteen pound selectively carbonized bond outgoing envelope face sheet positioned on top of, a sixteen pound selectively carbonized bond billing statement sheet positioned on top of, a twenty-four pound register bond reply envelope face sheet positioned on top of, a twenty pound register bond reply envelope back sheet positioned on top of, a twenty pound register bond outgoing envelope back sheet. This unique combination of paper types and weights enables information to be imparted through the several sheets using conventional narrow carriage impact printers which typically do not have a tremendous amount of striking force. This unique combination of paper types and weights combine to make a very strong and durable piece that will withstand the post office equipment punishment. 
   A method of making a postal envelope form system, may include printing a plurality of sheets, wherein at least some of the plurality of sheets have a selectively carbonized area to enable transfer of information between sheets; attaching the plurality of sheets together so as to form an outgoing envelope, and a reply envelope contained within the outgoing envelope, and wherein each of the outgoing and reply envelopes are able to have mail-to and return addresses preprinted thereon using the selectively carbonized area. These aspects allow forms to be created which will have complete information provided on various portions of the postal envelope form system using a conventional narrow carriage impact printer. 
   A method of using a postal envelope form system may include printing information on the postal envelope form system, the information including billing information; mailing an outgoing envelope having pre-preprinted first mail-to and return addresses, the outgoing envelope having contained therein a reply envelope having preprinted second mail-to and return addresses. Having preprinted reply envelope mail-to, delivery point barcode and return addresses along with a FIM mark allows for postal discounts to be qualified for. 
   A further aspect may provide preprinting textual information intended for being scanned by post office processing equipment in white areas located among colored areas to facilitate accurate delivery. This increases the accuracy in delivery since the high contrasting white areas contain the text required for scanning. This also allows color coding to distinguish between similar self-mailers from being misdelivered to an incorrect address based on appearance. White areas on the outgoing and reply envelopes may be 2/10 wider and taller than the matching text area shown on Part I to increase tolerance in collating the several sheets, and thereby ensure information to be scanned is located within high contrast areas. 
   A method using a postal envelope form system may include receiving a first envelope having preprinted first mail-to and return addresses, the first envelope having contained therein a second envelope for reply having preprinted second mail-to and return addresses, and providing at least one of payment and payment information, and mailing the reply envelope along with at least one of payment and payment information. These aspects allow users of the invention to readily return payment in compliance with postal requirements. A similar advantage may be realized by receiving at least one of a good and service; and receiving a first envelope having preprinted first mail-to and return addresses, the first envelope having contained therein a billing statement associated with at least one of a good and service, and a second envelope for reply having preprinted second mail-to and return addresses. 
   The outgoing envelope may include a flap enclosure and a tab opening means for easily opening the flap enclosure, wherein the tab opening means is located at a bottom of the outgoing envelope thereby allowing the biller return address to be located at a top of the outgoing envelope and the customer return address to be located at a top of the reply envelope. 
   A method of making a postal envelope form system may include printing a plurality of sheets, some of which have selectively carbonized areas used for transferring information impact printed thereon to a sheet underneath; forming lines of weakness in the plurality of sheets to allow easy separation of a billing statement from a reply envelope, both contained within an outgoing envelope; and gluing the plurality of sheets together to form the postal envelope form system. These aspects allow for both easy separation of form portions, while providing a reinforced edge that typically receives damaging treatment from postal processing equipment. 
   A line of weakness transverse to a height of the postal envelope form system may be provided thus creating a series of connected, but weakened, individual postal envelope form systems. This aspect allows for fast automated printing of a plurality of forms sequentially. 
     FIG. 1  is a perspective view of a postal envelope form system  10 . System  10  includes several sheets or parts that are attached together. System  10  is intended to be used as a self-mailer billing system where an outgoing envelope is mailed to a customer along with billing information and a reply envelope is to be used to return payment or payment information in exchange for goods or services rendered. 
   The several sheets shown in  FIG. 1  include a Part I  100  which is attached to a Part II  200 , which is attached to a Part III  300 , which is attached to apart IV  400 , which is attached to a Part V  500 , which is in turn attached to a Part VI  600 . Part I  100 , Part II  200 , Part III  300 , Part IV  400 , Part V  500 , and Part VI  600  are attached on right side edge  40  in order to strengthen portions of system  10  that undergo postal processing by processing equipment used in delivery of mail. 
   Part I  100  may be formed from a sheet of twelve-and-a-half pound selectively carbonized bond paper. The twelve-and-a-half pound designation is commonly understood in the paper and forms-processing industry as corresponding to the weight of 1000 sheets of a specific size of paper. The selective carbonization is dependent on the location of information printed on Part I  100  which is intended to be imparted onto other parts attached underneath. This will be described more fully below. 
   Part II  200  may be formed from a sheet of sixteen pound selectively carbonized bond paper. Part III  300  may be formed from a sheet of sixteen pound selectively carbonized bond paper. Part IV  400  may be formed from a sheet of twenty-four pound register bond paper, which is similar to carbonized bond with one exception that carbon is not attachable to the register bond paper as readily as with the carbonized bond paper. Part V  500  may be formed from a sheet of twenty pound register bond paper, and Part VI  600  may be formed from a sheet of twenty pound register bond paper. 
   Part II  200  and Part VI  600  may be attached together to form an outgoing envelope  20  which is readily separable from the other attached parts of system  10  as will be described in detail below. Outgoing envelope  20  may enclose Part III  300 , Part IV  400 , and Part V  500 . 
   Part IV  400  and Part V  500  may be attached together to form a reply envelope  30  which is readily separable from the other attached parts of system  10  as will be described in detail below. Part IV  400 , being made off thicker and heavier paper, provides significant strength to both the reply envelope  30  and outgoing envelope  20  which assists in preserving postal envelope form system  10  upon encountering processing machinery. Additionally, attaching Parts I–VI by gluing right side edge bolsters the durability of postal envelope form system  10  which typically progress through postal processing machinery with the right edge leading the remainder of the Parts. 
     FIG. 2  is a block diagram of Part I  100  which may form an originating sheet of the postal envelope form system. Part I  100  is the originating sheet upon which a printer prints information. The postal envelope form system  10  was designed for use with a relatively inexpensive impact printer (not shown) having a narrow carriage (e.g., Okidata Microline 320 Turbo). These types of printers are common in the industry due to their low cost and reliability. 
   The information printed by such printers may include billing information identifying the goods or services rendered, the time period covered, mailing information, and postage information, which are discussed further below. Part I and originating sheet will be used interchangeably hereinafter with reference to numeral  100 . 
     FIG. 2  depicts originating sheet  100  as having a colored area  101  among various and white areas that will be discussed individually. Reference is made to originating sheet  100  in conjunction with other parts throughout the remaining discussion. 
   Specifically, originating sheet  100  may include a sender return address area  102  within which a sender return address is printed before mailing (i.e., preprinted).  FIG. 2  also shows in cross-hatching a carbon spot  102   a  located on a back face (not shown) of originating sheet  100 . Carbon spot  102   a  enables the force of the impact printer used to impart information onto the sheet immediately below originating sheet  100 , which is Part II  200 . 
   Therefore, originating sheet (Part I)  100  is printed with the information that is intended to be printed on sheets beneath it. Thus, originating sheet (Part I) may be preprinted with all the information printed on system  10 . Originating sheet  100  also may include customer mailing address area  104  within which a customer mail-to address is printed before mailing along with a delivery point barcode discussed further in conjunction with  FIG. 3  below.  FIG. 2  also depicts in cross-hatching a carbon spot  104   a  that may be located on a back face (not shown) of originating sheet  100 . Carbon spot  104   a  enables the force of the impact printer used to impart information onto Part II  200 , which is the face of outgoing envelope  20 . 
   Originating sheet  100  may also include a postage permit area  106  within which postage permit information is printed before mailing. The postage permit information is that which the post office uses in assigning a postage charge and postage discounts to the sender. 
     FIG. 2  also depicts in cross-hatching a carbon spot  106   a  that may be located on a back face (not shown) of originating sheet  100 . Carbon spot  106   a  enables the force of the impact printer used to impart information onto Part II  200 , which is the face of outgoing envelope  20 . 
   Originating sheet  100  may be approximately five-and-a-half inches tall and nine- and five-eighths inches wide, which fits within narrow carriage impact printers that are typically approximately ten inches wide. Generally, forms similar to postal envelope form system  10  are approximately nine-and-a-half inches wide. However, system  10  may be made an eighth of an inch wider to accommodate areas large enough to include reasonable amounts of information, yet still fit within size dimension standards of the post office. The half inch tolerance typically provided was necessary for other forms, but the form of system  10  is able to reduce this by ⅛th of an inch. This allowed the width of system  10  to be increased to 9 ⅝th of an inch. 
   Since originating sheet  100  may include all the information printed on the various other parts of system  10 , originating sheet  100  is useful for keeping records of the sender. Furthermore, originating sheet  100  may incorporate a line of weakness or perforation  107  transverse to the width that allows a portion  107   a  to be separated from a portion  107   b . Portion  107   a  can be used as a reminder billing statement, while portion  107   b  can still be retained for record keeping purposes. Thus, originating sheet  100  can be used as a reminder bill or a collection bill, with both a customer receipt and a remittance copy. 
     FIG. 3  is a copy of the front face of originating sheet (Part I)  100 , and depicts placement of text within the various blocks shown in  FIG. 2 . Specifically, sender return address area  102 , customer mailing address area  104 , and postage permit area  106  are shown with text contained therein. Sender return address area  102  has a return address shown, but with the name of the sender removed for confidentiality purposes. The name of the sender may be printed uppermost in sender return address area  102 . Similarly, customer mailing address area  104  and postage permit area  106 , may have information printed uppermost in the areas  104  and  106 . In the case of customer mailing address area  104 , the uppermost information may be delivery point bar coding  108  that allows certain postage discounts to be credited to the mailer of outgoing envelope  20  upon which the bar coding  108  is transferred. A series of circular cuts  109  are located on each side of system  10 , in parallel, to form pin-feed margins that assist printers in feeding forms through a printing path during printing. 
     FIG. 4  is a block diagram of a front face of Part II, which forms a portion of an outgoing envelope  20  upon which the information in the sender return address area  102 , the customer return address area  104 , and postage permit address area  106  are imparted by the impact printer.  FIG. 4  depicts a colored area  202  within which white areas  102 ′,  104 ′, and  106 ′ are located. White areas  102 ′,  104 ′, and  106 ′ correspond to the sender return address area  102 , the customer return address area  104 , and postage permit address area  106  of originating sheet (Part I)  100 . Note boxes  102 ′,  106 ′ and  104 ′ on  FIG. 4  may be much larger than their corresponding twin images on  FIG. 3 . This may be necessary to insure scanability. 
   The colored areas  202  provide a visual indication that allows outgoing envelopes sent by the same sender to be easily identified with the sender. The colored areas of all parts of system  10  can be kept the same, or varied if desired, to create meaning associated with the colors. For example, all the colored areas of system  10  can be kept the same color to associate various parts being mailed at different times in reply with a particular mass outgoing mailing. Alternatively, various parts can be differently colored to provide an visual indication of which part among system  10  is being seen without having to refer to the contents of the part. 
   The white areas are purposefully not colored to enable the information printed within to be easily read by users and scanning equipment associated with postal envelope form system  10 . The information within the white areas is transferred from Part I  100  to Part II  200  is achieved through the selectively positioned carbon spots  102   a ,  104   a , and  106   a  located on the back face of Part I  100 . 
     FIG. 4  also depicts carbon areas  204 ,  206  and  208  which transfer information imparted by the impact printer onto originating sheet (Part I)  100  and through to a billing statement sheet (Part III)  300  ( FIG. 5 ). The information imparted by the impact printer onto originating sheet (Part I)  100  and that is transferred to billing statement sheet (Part III)  300 , may include information contained within the sender return address area  102  and within the customer mailing address area  104 . The information additionally may include a customer return address area  110 , a distributor or sender mailing address area  112 , a response detail area  114 , and a message area  116 . 
   The information contained within customer return address area  110  may be transferred by carbon spot  204  to billing statement (Part III)  300  within a customer return address area  310  shown in  FIG. 5 .  FIG. 5  is a block diagram of a front face of Part III, which forms a billing statement of the postal envelope form system and depicts colored areas  350  among which white areas such as customer return address area  310  are located. Other white areas located among colored areas  350  may include a sender return address area  302 , a customer mailing address area  304 , a sender mailing address area  312 , a response detail area  314 , and a message area  316 . The same information imparted to originating sheet (Part I) may be imparted to billing statement (Part III)  300 , with the exception of the postage permit  106  and a face identification mark (FIM) discussed below. Thus, billing statement (Part III)  300  contains complete information. 
     FIG. 5  may additionally include directions  320  that in the embodiment shown instruct the recipient of billing statement (Part III)  300  to “Please return this portion with your response. Thank You!”. The portion requested for return is a remittance copy  360 , which is separated by a line of weakness (perforation line)  362  from a customer copy  364 . Thus, a customer can retain customer copy  364  as a courtesy when the customer returns the remittance copy  360  with payment or payment information in reply to receiving billing statement (Part III)  300 . 
     FIG. 6  is a block diagram of the back face of billing statement (Part III)  300  shown in  FIG. 5 .  FIG. 6  depicts a front view of this back face billing statement (Part III)  300 , and shows carbon spots in patterned cross-hatching among a colored area  401 , The carbon spots in  FIG. 6  may be selectively positioned to correspond to the location of information imparted by the impact printer on originating sheet (Part I)  100  and to be transferred to similarly positioned areas on reply envelope  30  shown in  FIG. 7 . 
   Originating sheet (Part I)  100  may further include a face identification mark (FIM) area  140  that corresponds to a carbon spot  640  in  FIG. 6 . It should be noted that  FIG. 6  is a back view of billing statement (Part III)  300 , and is therefore a mirror image of the positioning of FIM area  140 . Similarly,  FIG. 6  includes a distributor mailing address area  612  which is a mirror image of the positioning of distributor mailing address area  112  shown in originating sheet (Part I)  10  ( FIGS. 2 and 3 ). The distributor mailing address area  612  is a carbon spot that imparts the address information of the sender of the outgoing envelope shown in  FIG. 7 .  FIG. 6  also includes a carbon spot  610  that corresponds in mirror image to customer return address area  110  shown in  FIGS. 2 and 3 . 
     FIG. 7  is a block diagram of a front face of Part IV, which forms a portion (the front sheet) of reply envelope  30  of the postal envelope form system of the present invention.  FIG. 7  depicts colored area  701 , and white areas which are a mirror image of carbon spots shown in  FIG. 6 . Specifically,  FIG. 7  shows a customer return address area  710 , a distributor mailing address area  712 , and a FIM mark  740  as white areas. Note boxes  710 ,  712  and  740  on  FIG. 7  may be much larger than their twin image on  FIG. 3 . This may be necessary to ensure scanability. The white area provides high contrast with the information contained therein which was imparted by the carbon spots  610 ,  612 , and  640  shown in  FIG. 6 .  FIG. 7  is a front view of reply envelope  30  and therefore the positions of areas  710 ,  712 , and  740  match with the positions of areas  110 ,  112 , and  140  shown in  FIG. 2 ; whereas the areas  610 ,  612 , and  640  of  FIG. 6  are mirror imaged in comparison because  FIG. 6  is a back view. 
     FIG. 7  also includes direction area  750  which in this embodiment instruct the user of reply envelope  30  to “PLACE STAMP HERE The Post Office will not deliver mail without Postage.” The postage placed at or near direction area  750  is cancelled by post office processing equipment. The inclusion of FIM  740  and a delivery point barcode in address area  712  on reply envelope  30  may allow the user of postal envelope form system  10  to qualify for additional postage discounts credited upon payment for mailing outgoing envelope  20 , as long as other criteria are met. The other criteria may include a threshold readability or accuracy level above which a percentage of the mailings sent by users must surpass. In the year 2000, 90% postal bar coding contained in mail-to address areas such as address area  712  must be scannable by postal processing equipment. If the 90% threshold is not meet, the discounts on postage are not given. These discounts can be approximately six cents per envelope which is quite significant when using business mailers to solicit payment for goods or services rendered from a very large number of customers. 
     FIG. 8  is a block diagram of a back face of Part IV, which forms the same portion of the reply envelope shown in mirror image of  FIG. 7 .  FIG. 8  depicts security screened areas  802 , and shows block-out areas in solid dark blocks  810 ,  812  and  840  which correspond to areas  710 ,  712  and  740  in  FIG. 7 . The security screened area  802  may prevent information contained within reply envelope  30  from being either read or scanned through the paper of envelope  30 . Dark blocks  810 ,  812  and  840  may enhance the scanability of the reply envelope address data in white block&#39;s  710 ,  740  and  712 . Blocks  810 ,  812  and  840  may prevent any image of envelope contents or security pattern from showing through the front of the reply envelope. This prevents information contained in the reply envelope under the areas of  710 ,  712  and  740  from being mistakenly scanned by postal processing equipment attempting to scan reply envelope  30 . It has been found that errors in scanning were reducing the accuracy rate required to qualify for the best postage discounts. 
     FIG. 8  also depicts a flap  880 , formed by line of weakness  885  and edge  886 , upon which moistenable glue is placed. Flap  880  can contain parallel lines of glue to better ensure that envelope  30  seals properly. Flap  880  may also serve as a direction area. The directions in this embodiment instruct the user to “MOISTEN THIS FLAP, THEN FOLD FLAP OVER TO SEAL”. Flap  880  folds about line  885  and attaches to the other portion of envelope  30  formed by Part V  500 . The directions in this embodiment also instruct the user to “Pull To Remove Contents”. The removal instruction is for separating the reply envelope  30  (Parts IV and V) and billing statement  300  (Part III) from outgoing envelope  20 . The separation is achieved in part due to lines of weakness formed before the various Parts I–VI are attached together. Specifically, line of weakness  883  is a perforation that allows easy separation by simply pulling reply envelope  30  (Parts IV and V) and billing statement  300  (Part III) from outgoing envelope  20 . Line of weakness  883  once completely weakened form the boundary of reply envelope  30  along with an edge  886 . 
   The return envelope of  FIG. 8  is bounded at its top by edge  882  and on its bottom by edge  886 . The right edge  883  connects the top edge  882  and the bottom edge  886 . The left end of the return envelope is formed by the line of weakness  881 . 
     FIG. 9  is a block diagram of a front face Part V of the back of reply envelope  30 .  FIG. 9  depicts a security screened area  900  that prevents sensitive information contained within reply envelope  30  from being easily read through the sometimes transparent sheets of paper forming the various Parts of postal envelope form system  10 . An edge  902  is attached, such as by glue, to a correspond edge on the back of Part IV  400  shown in  FIG. 8 . An edge  904  is left unattached so that an opening is formed in reply envelope  30 . 
     FIG. 10  is a block diagram of a back face of Part V, which is the outside of the other portion forming reply envelope  30 .  FIG. 10  depicts colored area  1002  and printed direction area  1004 . A flap  1006  formed by a line of weakness  1008  and an edge  1010  may be glued to a front face of Part VI  600  so that when a tab of Part VI  600  is removed, flap  1006  is removed along with it. In the event that flap  1006  is not removed as intended, instructions reading “REMOVE THIS PROTECTIVE COVER AT PERFORATION TO EXPOSE GUMMED FLAP BELOW” clearly tell the user what to do. The gummed flap referred to is that flap  880  mentioned above in conjunction with  FIG. 8 . 
     FIG. 10  shows the back face of part  4 , and has a protective flap  1006  defined by a line of weakness  1008  and the lower edge  1010 . This flap  1006  should preferably be removed before the envelope is sealed. 
     FIG. 11  is a block diagram of a back face of Part VI, which is the outside of the other portion of outgoing envelope  20  shown in  FIG. 4 .  FIG. 11  depicts a colored area  1102 , a direction area  1104  and a fast pull flap for opening the outgoing envelope  20 . Direction area  1104  instruct the recipient of outgoing envelope  20  how to operate fast pull tab  1111 : “TO OPEN—LIFT TAB AND SLOWLY PULL TO YOUR RIGHT”. Tab  1111  includes an unattached portion  1112  which can be lifted easily to grasp and pull tab  1111  at a line of weakness  1114 . Although the instructions indicate that the user is to pull to their right, the tab is located on the bottom (and printed upside down) relative to the orientation of the writing on the front faces of outgoing envelope  20  and reply envelope  30 . 
   This location and orientation of tab  1111  may be significant in many respects. The location of tab  1111  on the bottom and back of outgoing envelope  30  (as oriented by the writing on envelopes  20  and  30 ) allows the return address areas of envelopes  20  and  30  to be positioned at the uppermost edge since there is no interference with a conventionally placed folding closure flap. In other words, in conventional envelopes, the closure flap is placed at the top which would force the return address to be positioned only as high as the folding line. The position, location and orientation of tab  1111  does not force the return address of the outgoing envelope to be lowered. This allows a greater amount of information to be imaged on the various parts of postal envelope form system  10 . 
   Furthermore, tab  1111  may constructed with unattached portion  1112  and perforation  1114  to reduce damage to the contents of outgoing envelope  20  such as ripping or tearing the billing statement (Part III)  300  or reply envelope  30 . Similarly, reply envelope  30  has flap  880  located at the bottom which allows the return address area  710  ( FIG. 7 ) to be positioned uppermost (within certain tolerances) on reply envelope  30 . This allows a greater area for message areas  116  ( FIGS. 2 and 3 ), message area  316  ( FIG. 5 ), and response detail areas  114  and  314 . 
   Having fully described a preferred embodiment of postal envelope form system  10  above, a few additional points should be made to elaborate on how the preferred embodiment shown in system  10  may provide certain advantages and meet various needs identified in the industry. First, narrow carriage impact printers have limitations that the design had to overcome, one being the maximum width of the form being ten inches. Second, the striking force of impact printer&#39;s print head limits the number and weight paper being used. Third, the print speed of narrow carriage printers is slow compared to other options. 
   In this embodiment, the form may be kept as small as possible to limit wasted motion of the print head, to fit within narrow carriage impact printers, to fit size dimension standards of the post office, and to weigh approximately less than one ounce. Managing the strike force of the impact printer head may be achieved by the combination of paper weights and other characteristics. 
   In this embodiment, system  10  may provide complete return address and mail-to address information on both the outgoing and the business reply envelopes  20  and  30 . The billing statement (Part III)  300  may have a vertical perforation that separates the sheet into remittance copy  360  and customer copy  364 , both of which may have complete information due to the careful positioning of areas throughout the various parts. The information on both portions may include: (1) name and address of sender; (2) name and address of customer; (3) detailed information on the customer copy; (4) response information on the billing statement; (5) account numbers on both portions; (6) postal bar coding on each envelope; and (7) the FIM mark on the reply envelope. 
   System  10  is very flexible in that it allows postage indicia to be printed thereon, or a stamp or metered postage to be used. FIM marks are not required on all mail, and system  10  allows FIM mark to be imaged or not imaged. When used, FIM marks have been tested in postal processing equipment and achieved a 99.9% readability rate. System  10  also allows postal bar coding to be printed when desired. 
   Furthermore, postal endorsements are required periodically and several options are available to post office customers. These endorsements come with various costs charges by the post office and each one has differing verbiage. The post office requires use of such endorsements once every six months, however, postal customers using system  10  can use the endorsements monthly if they choose. Complete freedom of which endorsement is used, how frequently it is used, or use of a different endorsement on each mailing is possible using system  10 . Additional flexibility is provided by choosing which color system  10  will be. 
   Contrast is an important element of being able to read the address and postal bar coding on the envelopes by the post office scanning equipment. System  10  takes advantage of this by focusing the scanner&#39;s attention to the vital data area. These areas are the mail-to address, return address, the FIM mark, and postage permit area. These areas may be white with contrasting dark printing, or other highly contrasting combinations of colored area and colored information therein. The boxes that form these focal areas may allow 1/10th of an inch free space around the data image area. The post office standards require 1/25th of an inch free space around all scannable data. In originating sheet  100  the colored portions are located between addresses  102  and  110 , between areas  114  and  116 , and between postage permit  106  and area  114 . The balance of the surface may be printed in an ink color which causes reduced contrast. The post office scanners find the data in the high contrast areas. 
   Locating the postal bar coding in the mail-to address areas in envelopes  20  and  30  may also be very important. In a preferred embodiment, the barcode be the first line printed, and is located at the very top of the address box as seen in  FIG. 3  in areas  104  and  112 . This moves the barcode up and out of the way of the post office handling equipment that is most viscous to the area which otherwise smudges the barcode. The positioning shown in  FIG. 3  improved readability of the barcode from 60% to 98% after six passes through the postal equipment. The business reply envelope address may be located above the outgoing address area which protects the barcode therein from similar damage. The reading results of the business reply envelope is 95% after going through the postal equipment 12 times. 
   Another important feature of system  10  may be the block-out patterns which are printed on the inside of the envelopes. This prevents data or information contained within the envelope from being scanned and interfering with barcodes or address lines. The fine screened box of system  10  appears to be solid to scanners, so there is no mistaking a pattern as information. 
   The positioning of tab  1111  on the bottom backside of the envelope may also very important to the success of system  10 . First, locating tab  1111  on the bottom of the envelope  30  permits variable information to be imaged to the very top of the form. This allows the complete form design to be moved up to the very top of the envelope. The top may be the ideal position for the return address information for the outgoing and reply envelopes  20  and  30 , FIM  740 , and postal indicia  106 . This change allows the postal barcode to be moved up out of the way of the post office equipment in order to limit damage and smearing to improve readability. 
   Orientation of tab  1111  may also be very important to control of damage resulting from post office processing equipment. Tab  1111  is best located behind the left side of the face of the envelope  20 ; in other words, on the right side facing the back of envelope  20 . This orientation prevents the tab  1111  from accidentally being snagged and opened while traveling through the postal equipment. 
   Crumple damage control of the right vertical edge of system  10  may also be important. Post office equipment has a catch or bar stop that blocks the envelope path when the envelope hits the stop. The impact of envelopes  20  and/or  30  against the catch can cause crumple damage to the mail piece. This damage can lead to the ordinary mailers being further damaged or destroyed by postal handling equipment. System  10  may reinforce the right edge  40  to minimize crumple damage. 
   Lastly, the paper weights and characteristics have been selected very carefully to yield durability and strength, while allowing imaging through all parts. Other paper weight combinations can be used, as various other combinations have been tested. However, the combination of types and characteristics provided herein represent the best mode known to date. 
   System  10  provides readability by postal scanners of barcode on both outgoing and reply envelopes higher than the requirement established by the year 2000 goal of 90% accuracy. Block out blocks, such as solid blocks  840 ,  810  and  812 , can also be applied to standard envelopes (e.g., only a single envelope not necessarily contained in a system) to improve postal scanning of alpha numeric address information. System  10  provides an ergonomic design of forms, which reduces injury to users hands and arms from repetitive manual bursting. This is accomplished this by weakening the pin feed and between form perforations by using perforation that have wider cuts and narrower ties between perforations. This weak perforation requirement for the purpose of protecting the health of the user and the employees has never been accomplished before. 
   System  10  is extremely flexible and user friendly. For instance, customers can change addresses without concern of form cost. 
   System  10  establishes focal points on both outgoing and reply envelopes in the form of white boxes which contain the variable data in the form of to and from addresses, delivery point barcodes and FIM mark. These focal points helps the postal equipment to find, read and sort with a very high degree of accuracy approaching 100%. Managing printer impact on system  10  to achieve a scan accuracy of almost 100% may require careful selection of paper weights. 
   While this system has been described in connection with what is presently considered to be the most practical and preferred embodiments, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the appended claims. For example, fewer than six parts could be used while still imparting substantially the same information on the number of parts actually used. Additionally, another embodiment could replace the originating sheet with an electronically stored version of the information contained on the originating sheet, thereby allowing fewer than six parts to be used. Furthermore, it is envisioned that other paper types and weights combinations could be readily used to achieve transfer of information through the number of parts used in an embodiment. Alternatively, when greater than six parts are used, adjustment of part weights and types may be necessary to image through the parts, depending on printer strike force. Similarly, improvements in either impact printers and/or postal processing equipment in use may bring about other embodiments, as long as the printer used is able to legibly impart the information that is readable/scannable by the postal processing equipment.
