Title: Multi-part non-impact printer airbill form

Description:
CROSS REFERENCE TO RELATED APPLICATION 
     This is a continuation-in-part of U.S. patent application Ser. No. 08/377,126, filed Jan. 23, 1995, now U.S. Pat. No. 5,899,504. 
    
    
     BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     This invention relates to a multi-part mailing form for use with a non-impact printer, and more particularly, to an airbill form which may be used for addressing packages sent by an overnight mail service. 
     2. Background Information 
     Overnight air courier services have become a common mode to send original documents and goods. Examples of such services include the Express Mail service of the United States Postal Service, Federal Express, United Parcel Service, DHL, Airborne, and many others. Most commercial air courier services utilize a similar multi-part airbill form comprising several layers of superimposed sheets, each of which must bear certain address information. The name of the shipper and the name of the recipient are printed once and appear on all sheets of the airbill form. 
     Current multi-part airbill forms typically have four sheets: one sheet for the sender, one sheet for the recipient signature as a proof of receipt, one sheet for the package, and one sheet for the air courier&#39;s billing department. Many of the various multi-part airbill forms used by air courier services have a peel away backing which exposes a pressure sensitive adhesive for affixing the airbill form to the package being sent. 
     In order to use these airbill forms, it is necessary to inscribe the addresses of both the recipient and the sender on each of the sheets of the airbill form. Carbon paper or coatings of microcapsules are normally used to permit the user to add the information only one time on the top sheet and still have it appear on the remaining sheets. Nevertheless, the address information must be added to the airbill form by either a typewriter, an impact printer, or by hand. Most offices today utilize computers because of their well-known advantages over typewriters and manually prepared documents. Further, most computer systems used in offices are linked to a non-impact type printer, such as the laser printer or ink jet printer, because of the speed and quiet operation of non-impact printers compared to the older impact printers or typewriters. 
     Because of the non-impact type of printing equipment used in modern offices, the address information added to air courier airbill forms must be done manually. This results in inefficient use of time if done by typewriter or, if done by hand, can leave the air courier company with the problem of reading the handwriting of someone else. Though manually adding the address information to airbill forms may be done easily enough where a small number of packages are to be sent, it is very inefficient where a large number of packages are to be sent. In the latter case, it is desirable to use a computer and associated printer to prepare the airbill forms. For example, where a mail order vendor ships merchandise by overnight air courier, many hundreds or thousands of airbill forms must be prepared daily and manual preparation of the airbill forms is very tedious and difficult. With current airbill forms, the only manner of using a computer is to utilize an impact printer, which is both slow and noisy. Non-impact printers, which are faster and quieter than impact printers, cannot be used because of the requirement to have the address information on each sheet of the existing multi-part airbill forms. 
     What is needed is an air courier airbill form which can be printed using a non-impact printer. 
     SUMMARY OF THE INVENTION 
     In accordance with one aspect of the invention, there is provided a multi-part form for use as a mailing form for placement on a package, in which address information is printed by a non-impact printer on one side of the form proximate to the time the form is to be used. The form includes a substantially opaque first panel on which certain information, e.g., address information, can be printed and a substantially transparent or translucent panel on which certain information, such as an address, can be printed. The transparent panel is divided from the first panel by means permitting the folding of the first panel over the transparent panel. Advantageously, the information printed on the form can be printed on one and the same face of each of the panels, thus allowing for printing by a non-impact printer in communication with a computer having a database which holds information which can be directed to be printed on the form. Preferably, the address information printed on the transparent panel is a mirror image to the normally readable address information printed on the first panel. Further, there is included means for affixing the one printed face of the transparent panel to the package and means for affixing the back or opposing face of the non-impact printed face of the first panel to another portion of the form or to the package. 
     A second embodiment of the invention concerns a multi-part form comprising a plurality of separate panels affixed together as a single sheet for use as a mailing form, e.g., airway bill, waybill, bill of lading, or the like, on a package. The panels are folded over to be superimposed with one another for use as a multi-part, manifold form. Address information can be printed on one and the same face of each panel of the form by a single pass through a non-impact printer proximate to the time the form is used. This embodiment having a plurality of panels affixed together comprises at least a first substantially opaque panel and a substantially transparent or substantially translucent panel. For convenience, the transparent or translucent panel is hereinafter referred to as the “transparent panel” but would be understood to be either substantially transparent or translucent such that printed information disposed on one face of this panel shows through and can be read from the other face. The panels can also be independently pre-printed on either face with certain background colors or information, e.g., instructions for use. 
     The first panel, which is a top panel when the form is in folded configuration and placed on a package, is preferably a paper material having a substantially white background and capable of being printed on by a non-impact printer. The transparent panel, forming a bottom panel when placed on a package in folded configuration, is preferably a substantially transparent or translucent paper or plastic, also capable of being printed on by a non-impact printer. 
     In a preferred variant of this second embodiment, the mailing form comprises at least three panels and is described herein as having three panels. The first and second panels form each end of a single sheet and are separated from each other, adjoined by a third substantially transparent or translucent panel (hereinafter “the transparent panel”) affixed therebetween. The first and second panels are preferably substantially light-colored, or white, background paper capable of being printed on by a non-impact printer. The transparent panel is preferably a substantially transparent or translucent paper or plastic also capable of being printed on by a non-impact printer. 
     In this variation of the second embodiment, each of the panels is overlapped with its adjacent panel and forms a section approximately one-third the area of the mailing form such that the first and second panels can be folded over the transparent panel to form a three-part, manifold mailing form. The transparent panel can be positioned such that the printed face contacts the package such that the address information printed thereon is readable therethrough. The non-impact-printed faces of the first and second panels, being folded over the transparent third panel, position the printed face of those panels such that they are facing away from the package and are thereby also readable in that folded configuration when not covered by an overlying opaque sheet. 
     Further, this second embodiment of the subject invention comprises a means for affixing at least a portion of the printed face of the transparent third panel to the package. A means can also be provided for affixing the second panel in folded configuration to the transparent panel or to the package, and the first panel to either the second panel or to the package in the folded configuration. Preferably, these affixing means include disposing adhesive in a strategic position across the width of the panels so that the panels adjoin in a folded configuration to provide a three-part mailing form. This embodiment thus provides a three-part, manifold mailing form wherein the transparent panel is used as the bottom layer of the manifold form and is permanently affixed to a package. The other two panels are affixed to their respective underlying panel or to the package, but are removable therefrom by a separation means, e.g., a perforation. 
     In accordance with another aspect of the invention, there is provided a method of using a multi-part form, as described hereinabove, as an address form for a package. The form can be pre-printed to include colored edges or borders or can also include instructional information. The method includes the steps of printing the address information on the first and transparent panels on one face of the form, such that the address information printed on the transparent panel is a mirror image of the normally readable address information printed on one or more of the panels. Further, the method includes the steps of affixing the one printed-on face of the transparent panel to the package, folding the opaque panels over the transparent panel, and affixing the opaque panels to one of another portion of the form or to the package. 
     As the method specifically applies to the second embodiment, information, such as an address, can be printed by a non-impact printer on one and the same face of each of three panels of the form. The first panel and the second panel are printed in a configuration such that they are readable from one direction, i.e., in a normal left to right configuration, when the printed face is exposed or positioned to face away from the package. The transparent panel is printed such that the information is a mirror image to the information printed on the first and second panels. The non-impact printed face of the transparent panel can then be affixed to the package by use of the affixing means such that the printing shows through the transparent panel in a normal, left-to-right, readable manner. The second panel is then folded over and affixed to the transparent panel or to the package. The first panel can then be folded over the second and transparent panels and affixed to the second panel or package to form a mailing form or label having three parts folded over one another, each readable in the same direction. 
     In accordance with another aspect of the invention, there is provided a method of manufacturing the first embodiment of a pre-printed multi-part mailing form for a package. The form of the first embodiment includes a pair of transparent sheets, each forming one ply of the two-ply form. The method includes the steps of printing foreground information and a background color on one of the sheets. The background color is printed only on a portion of the one sheet and the foreground information on that portion being printed in a mirror image format relative to the remaining foreground information. The method further includes the steps of coating an adhesive on one of the sheets and affixing the sheets together so that the adhesive is between the sheets to adhere the plies together. 
     A method for manufacturing the second embodiment of the multi-part mailing form for a package is also included as part of the subject invention. The method comprises the steps of providing at least one substantially opaque panel, preferably having a background color which contrasts with the print color to be applied, and a substantially transparent panel. The first panel can be pre-printed to include instructional information. A permanent adhesive can be provided between the first panel and the transparent panel, along an overlapping edge of the two panels for affixing together these panels. A second substantially opaque panel, having a background color in contrast to the print, can also can be pre-printed and overlappingly affixed to the transparent panel at its edge opposite that of the first panel. The second panel and transparent panel can be affixed by an adhesive means disposed between overlapped edges of the second panel and the transparent panel. The first and second panels are preferably affixed to the transparent panel by slightly overlapping the edges to form a substantially inseparable bond. 
     Means for affixing a panel of the form to the package or affixing one panel to another in a manifold configuration can also be applied to the panels. Preferably, adhesive is applied in strategic locations parallel and proximate to the overlap junctures of the panels. A pair of adhesive strips can be applied near the junctures of the first and second panels with the transparent panel to affix the transparent panel to the package. Another strip of adhesive is applied to the second panel just inside or offset from the juncture edge such that the outer edge of the first panel can be affixed thereto when folded over the second panel. More preferably, the adhesive is applied as a continuous strip, as intermittent dots, or as spots of adhesive alternating with spots of adhesive-release material, along an edge of a contacting face of the panels. The adhesive strips are preferably covered by a peel-off, protective covering that can be removed to expose the adhesive for use. 
     Instructional information, including diagrams for directing appropriate use of the form can be pre-printed on either face of the first and second panels. 
     The subject invention also concerns novel chemical coatings for providing carbonless transfer of information inscribed on a top panel of the form to underlying panels. The chemical coating of the subject invention advantageously provides for improved transparency of the transparent panel and adheres to the transparent material better than conventional coatings.

     DETAILED DESCRIPTION OF THE INVENTION 
     Referring to FIGS. 1,  2  and  3 , a three-part airbill form  10  is shown and constitutes a first embodiment of the subject invention. As best seen in FIG. 3, airbill form  10  has two plies,  12  and  14 , superimposed and affixed together by a permanent, pressure sensitive, adhesive  16 . FIG. 1 shows the outward facing face of top ply  12  of airbill form  10  and FIG. 2 shows the outward facing face of bottom ply  14 . In the first embodiment, airbill form  10  is divided into three panels, top panel  18 , middle panel  20  and bottom panel  22 , each of which is one of the three-parts of airbill form  10 . The three panels  18 ,  20  and  22  may respectively be the proof of delivery receipt; the addressee&#39;s receipt; and copy for the finance department of the air courier service, which is used for billing purposes. In the three-part airbill form  10 , there is no sender&#39;s receipt, as it is contemplated that computers will be used to generate the address information and the sender&#39;s receipt information, such as the airbill number, can be stored in the computer generating the addresses. Where a sender&#39;s receipt is desired, a four-part variation of this embodiment, shown in FIGS. 7,  8  and  9 , may be used. 
     Each of the two plies  12  and  14  may preferably be a transparent polyester film, such as Melinex 1311, one distributor of which is Plastic Suppliers, 1174 Hayes Industrial Drive, Marietta, Ga., 35062. Melinex 1311 is a clear film with anti-static properties on both surfaces of its web. Its surface resistivity, independent of gauge, is 2×10 10  ohms/square, which overcomes the static electricity and laser corona-based problems which generally prevent stacks of plastic films from being used with laser printers. Moreover, Melinex 1311 film does not suffer from unacceptable shrinkage when passed through the high heat of the fusing stage of a laser printer. Melinex 1311 polyester film is described in more detail in U.S. Pat. No. 4,371,489 in the name of Patrick T. McGrall and entitled “Production of Antistatic Thermoplastic Films”. Additional problems encouraging the use of Melinex 1311 film are discussed in co-pending patent application Ser. No. 08/394,062, filed Dec. 1, 1994, and entitled “Transparent Security Pocket Compatible With Non-impact Printers”. 
     The three panels  18 ,  20  and  22  on ply  12  are separated by perforated cuts  24  and  26  through ply  12  and the three panels  18 ,  20  and  22  on ply  14  are separated by die cut lines  28  and  30  through ply  14 . These cuts  24 ,  26 ,  28  and  30  permit the panels  18  and  22  to be separated after plies  12  and  14  are affixed together by adhesive  16 , printed, folded, and applied to a package to be sent, as explained in more detail hereafter. 
     For airbill form  10  to be most efficiently used with a standard non-impact simplex printer, it is desirable that the printing only occur on one face of airbill form  10 . In the first embodiment of airbill form  10 , as shown in FIGS. 1-3, the printing by the non-impact printer occurs on the outward facing face of back ply  14  and comprises, at least, the addressee&#39;s address. Airbill form  10  is normally pre-printed during manufacture with constant information and instructions so as to appear similar to currently existing air courier airbill forms. For example, lines defining the addressee and return address blocks and instructions may be pre-printed, together with lines for signatures, accounting information, tracing information, and the like. Items, such as the sender&#39;s return address, account number and airbill number (in both digital and bar code format) may be either pre-printed or printed by the non-impact printer, depending upon the number of airbill forms ordered from the air courier service by the user/sender. 
     Certain information, such as internal tracing information, addressee&#39;s signature and accounting or billing information, can be manually added to the airbill form after a package is transmitted by the sender and this information also should appear on all copies of airbill form. In order to permit later added information to be manually added on the top sheet only, coatings of chemically mated imaging materials are placed on the facing faces of plies  12  and  14  of the first embodiment, or on each of the panels of the second embodiment, to form carbonless copies. As is well known, carbonless copies can occur where layers known as a CF (coated front) coating and a CB (coated back) coating are facing one another. A CF coating is a-dry chemical coating on which the information appears and a CB coating is containing microcapsules, each of which, in turn, contain a wet chemical. Where a CF coating and a CB coating are facing one another, adequate pressure will cause the capsules to rupture and a chemical reaction occurs between the dry and wet chemicals, thereby causing an image to appear. Such coatings are well known and commercially available from several vendors. 
     In three-part airbill form  10 , CB coatings  32  and  34  are placed on panels  18  and  22  of ply  12 , respectively, and CF coatings  36  and  38  are placed on panel  20  of ply  12  and panel  22  of ply  14 , respectively. The CB coatings  32  and  34  and CF coatings  36  and  38  are positioned so that when panel  22  is folded along lines  26  and  30  to be over panel  20  and then panel  18  is folded along lines  24  and  28  to be over panel  22 , the CB and CF coatings  32 ,  34 ,  36  and  38  are aligned with one another and a CF coating  36  and  38  and a CB coating  32  and  34  face one another with the CF coating positioned to receive the image. The variation shown in these figures has such coatings in discrete areas of the ply. However, it would be understood that the plies can receive full-face coating so that any area normally inscribed can transfer the image to the underlying ply. 
     Because it is difficult to write on a plastic film, a matte coating  40  is placed on panel  18  of ply  14 , which also is aligned with the CF and CB coatings  32 ,  34 ,  36  and  38  and is positioned on the outward facing surface of panel  18  after airbill form  10  is folded as explained above. One example of a matte coating which may be used with the airbill form  10  is Craigcoat 1025M, manufactured and sold by Craig Adhesives and Coating Company of Newark, N.J. These matte coatings can also be applied to the full face of the ply. 
     In addition to the perforation cuts  24  and  26  and die cut  28  and  30 , a die cut  42  and aligned-perforation cut  44  are placed approximately one-fourth to one-half of an inch below the upper edge of plies  12  and  14 , respectively. Further, die cuts  46 ,  48 ,  50  and  52  are placed in panel  20  of bottom ply  14 , approximately one-fourth to one-half of an inch away from die cuts  28  and  30  and the outer edges of ply  14 . 
     Referring now to FIG. 3, an exploded cross-sectional view, taken across lines  3 — 3  of FIG. 1 is shown, where it is seen that top and bottom ply  12  and  14  are held together by adhesive  16 . A layer of silicone release material  54  is placed on the interior surface of top ply  12  and in alignment with die cut  42  and perforation cut  44 . An additional layer of silicone release material  56  is placed on the interior surface of bottom ply  14  in alignment with and between die cuts  46  and  28 , die cuts  48  and  30 , die cuts  50  and the edge of ply  14  and die cut  52  and the edge of ply  14 . The addition of the silicone material layer  54  permits a strip  58 , defined by die cut  42  and the edge of ply  12 , to be peeled away, as best seen in FIG.  1 . 
     Release product components, manufactured by the GE Silicones division of General Electric Company, U.S.A., yield such a compatible release material. More specifically, the use of UV9400 solventless UV release polymer, in combination with UV9380C or UV9310C photocatalysts, can be photocured in air, upon irradiation with UV radiation of less than 300 nm wavelength, to provide a silicon release material having a tightly cross-linked epoxysilicone network. GE Silicones 1178-116 Viscosity Modifier can be used to help in forming precise patterns or discrete areas of release coating  24 . 
     The addition of the silicon material layer  56  permits a rectangular strip  60 , defined by die cuts  46  and  28 , die cuts  48  and  30 , die cut  50 , and the edge of ply  14  and die cut  52  and the edge of ply  14 , to be peeled away, as best seen in FIG.  2 . When strip  58  and rectangular strip  60  are peeled away, adhesive  16  is exposed. The exposed adhesive  16  below rectangular strip  60  is used to affix the folded airbill form  10  to a package, as seen in FIGS. 5 and 6, and the exposed adhesive below strip  58  is used to affix airbill form  10  together as a folded three-part airbill form, as seen in FIG.  6 . As seen with respect to strips  58  and  60 , adhesive  16  is coated to be slightly remote from the edge of airbill form  10 , to prevent bleeding of adhesive material prior to and during the use of airbill form  10 . 
     Adhesive  16  should be a transparent adhesive and should have a good affinity to both plies  12  and  14 , as well as having the ability to affix airbill form  10  to a package, which typically is a paper or cardboard material. One commercially available adhesive which has been found to be acceptable is a compounded synthetic polymer, such as Craigcoat 1051G, manufactured by Craig Adhesives and Coatings Company, of Newark, N.J. 
     As noted above, airbill form  10  is pre-printed during manufacture to closely resemble existing air courier airbill forms. This requires printing both a background color, such as white, and the information, which may be printed in various colors. For example, a U.S. Postal Service Express Mail airbill form has orange and blue borders and printing and a white background on all parts. On some sheets, black printing used to identify the airbill number in both readable format and bar code format is also present. Similarly, a Federal Express airbill form has blue, orange, yellow and black printing with a white background on two sheets, light blue, and yellow printing with a white background on a third sheet and blue and orange printing with a pink background on a fourth sheet, used as the customer&#39;s receipt. 
     The pre-printing, as shown in FIG. 3, is preferably placed on the interior facing face of ply  14 , and is done in two separate steps. First, the foreground information, represented by line  62 , is printed over all three panels  18 ,  20  and  22 . Foreground information  62  is printed in a standard readable format (when looking directly thereat) on panel  20  and in a mirror image and opposite direction format on panels  18  and  22 . Next, the background color printing  64  is printed only over panels  18  and  22 , leaving panel  20  with a transparent background. As noted above, different background colors  64  may be printed on panels  18  and  22  where different color panels, or parts, of airbill form  10  are desired. By pre-printing the background color (or colors)  64  only on panels  18  and  22 , middle panel  20  is transparent and top and bottom panels  18  and  22  appear as a conventional opaque air courier airbill. Alternatively, only the background color  64  may be pre-printed on the interior facing face of ply  14  and all of the information  62  may be printed by the non-impact printer at the time airbill form  10  is being used. 
     It should be noted that the silicone layers  54  and  56  are added after the foreground and background printing  62  and  64  occurs, so that information can be printed and viewed on strips  58  and  60 . It further should be noted that instructions or other information may be pre-printed on the outward facing face of panels  18  and  22  of ply  12 . 
     After airbill form  10  is manufactured, as described above, it is a flat sheet of conventional standard size, such as 8½″×11″ or A4, and is ready for use by a user. The user generated information to be printed includes both the addressee information and any other information desired by the user, such as return address (if not pre-printed), customer numbers, shipping or delivery information or instructions, billing or fee information, airbill number, and the like. The user generated information should be printed on the outward facing face of ply  14 , so that it is remote from CB coatings  32  and  34 , which can be damaged by the heat in some types of non-impact printers, such as a laser printer. The format of the user generated printed information is shown in FIG. 2, where it is seen that the printing on opaque panels  18  and  22  is conventional and readable and the printing on transparent panel  20  is in a mirror image format and in the reverse direction relative to the printing on opaque panels  18  and  22 . This is opposite to the pre-printed format. Care should be taken to assure that the direction of the printing, both pre-printed and user generated, is in the same direction so that the information is printed in the correct blocks. Thus, an arrow indicating feed direction may be a part of the pre-printed information on one of the panels  18  or  22 . 
     A computer program may be used to generate the user information and format to be printed and to send that information to the non-impact printer in a known manner. Such a program forms no part of this invention and is well within the state of the art. 
     Referring now to FIGS. 4-6, the manner of affixing airbill form  10  to a package  66  will be described. After the user generated information is printed, rectangular strip  60  is removed, as seen in FIG. 4, thereby exposing the adhesive  16  thereunder. Airbill form  10  is then placed on package  66  so that it becomes affixed thereto by applying a slight pressure above exposed adhesive  16 . Next, the ply  14  face of middle panel  20  is affixed to package  66 , by applying a slight pressure above the exposed adhesive  16  at rectangular strip  60 . At this point, the package  66  forms the background color for transparent middle panel  20 , thereby permitting both the pre-printed and user generated printing thereon to be easily readable. As previously noted, the pre-printed information on the interior face of panel  20  on ply  14  is printed in a directly readable format on the interior facing face of ply  14  at panel  20  and the user generated printing on the outward facing face of ply  14  at panel  20  is printed in a reverse mirror image format. Thus, a person can easily read all of the information through transparent panel  20  when it is affixed to package  66 . 
     After airbill form  10  is affixed to package  66 , panel  22  is folded about perforation line  26  to the position shown in FIG.  5 . Then, strip  58  is removed and panel  18  is folded about in perforation line  24  to the position shown in FIG.  6 . At that point, the adhesive  16  exposed by the removal of strip  58  is affixed to panel  22  by applying a slight pressure. This completes the affixation of airbill form  10  to package  66 . While panel  18  is shown as affixed to panel  22 , the dimensions and positioning of panels  18 ,  20  and  22  may be arranged so that the exposed adhesive  16  below strip  58  is affixed directly to package  66 , as seen by the dashed lines  68  in FIG.  6 . 
     As seen in FIG. 6, each of the CB layers  32  and  34 , the CF layers  36  and  38  and the matte layer  40  are in alignment after folding and affixation of airbill form  10  to package  66 . Further, a CB layer  32 ,  34  and a CF layer  36 ,  38  are facing one another between panels  20  and  22  and between panels  22  and  18 . Thus, when information is manually added to airbill form  10  by either personal of the air courier service. or by the addressee signing the proof of delivery receipt, that information is added over matte layer  40  and appears on the CF layers  36  and  38  on panels  20  and  22 . 
     During transit of package  16 , the three-parts of airbill form  10  may be separated by manual separation along perforation lines  24  and  26  and panels  18  and  22  of airbill form  10  may be sent as desired by the delivery person, leaving the affixed panel  20  as the addressee&#39;s receipt. 
     Referring now to FIGS. 7-9, a four-part airbill form  70  is shown. Airbill form  70  is generally similar to airbill  10 , shown in and described with respect to FIGS. 1-6, except that a fourth panel  72  is added below panel  22 . In FIGS. 7-9, like numerical designations are given for identical components previously described. The outward facing face of panel  72  on ply  12  has a CF coating layer  74  applied thereto-and the outward facing face of panel  72  on ply  14  has a CB coating layer  76  applied thereto. Further, the length of panel  72  is slightly shorter than the other panels  18 ,  20  and  22 , so that a standard 8½ by 14 inch sheet may be used for airbill form  70 . On ply  12 , panel  72  is separated by a perforation cut  78  from panel  22  and on ply  14 , panel  72  is separated from panel  22  by a die cut  80 . The printing on panel  72  is similar to that described above for panel  20 . 
     In using airbill form  70 , first rectangular strip  60  is removed and airbill form  70  is affixed to package  66  as described above with respect to airbill form  10 . Next, panel  72  is folded about perforation cut  72  so that the panel  72  of ply  14  faces panel  22  of ply  14 . Thereafter, the assembly of airbill form  70  is generally the same as with airbill form  10 , in that panels  72  and  22  are folded along perforation cut  26 , strip  58  is removed, panel  18  is then folded along perforation cut  24  and the exposed adhesive  16  from the removal of strip  58  is used to affix panel  18  to panel  22 . The reason that panel  18  is affixed to panel  22  is that panel  72  is slightly shorter than the other panels  18 ,  20  and  22 . Alternatively, the exposed adhesive  16  on panel  18  may be affixed to package  66 , as seen by the dashed lines  68  in FIG.  6 . 
     While the subject invention has been described with reference to the preferred embodiments, many variations are possible within the scope and spirit of the invention. For example, any number of panels may be designed by either adding additional panels to those shown and described or by removing panels from the three panel embodiment of form  10 . Further, the pre-printed matter may be on the outward face of ply  14 , in which case the pre-printed information will be over printed by the non-impact printer, in this case, the pre-printing on panel  20  and  72  will be the mirror image format. In this case, the pre-printed background color will be printed first and then the pre-printed information will then be printed over the background color. In addition, the background color and pre-printed information may be printed on different plies  12  and  14 ; for example, the background color  64  may be printed on the interior face of ply  12  and the pre-printed information  62  may be printed on the interior face of ply  14 . 
     Another alternative is to use a low tack, pressure sensitive, adhesive coating in alignment with strip  58  in place of high tack adhesive  16 . One such low tack adhesive is Craig-Stik 3991PI, manufactured and sold by Craig Adhesives and Coating Company, of Newark, N.J. Low tack adhesives are commonly used with self stick note pads, where a sheet of paper can be easily removed without tearing from the pad and affixed to another object. By using the low tack adhesive, it is unnecessary to include the silicone layers  54 ; in addition, perforation  44  may be eliminated, since the end of panel  18  can be easily removed from affixation to panel  22 . It should be noted that permanent adhesive  16  is still used in areas other than in alignment with strip  58 . 
     In describing the second preferred embodiment, reference is made to FIGS. 10-12. FIG. 10 is a front view of the form  100  showing the face to be printed on by a non-impact printer. The form comprises three separate panels: first panel  110 ; second panel  130 ; and third, transparent panel  120 . The three panels are adjoined by overlapping and adhering one edge of each of the first and second panels  110  and  130  to opposite edges of the transparent third panel  120 . Releasable protective coverings  121 ,  122 , and  123  are shown overlaying adhesive strips. The adhesive strips are disposed on the form to provide adherence to the package or for adhering panels to one another when forming the manifolded form. 
     The overlapping configurations of the panel edges are illustrated in FIGS. 11 a  and  11   b.  One configuration, shown in FIG. 11 a,  provides the first and second panels  110  and  130  overlapped on the same face of the substantially transparent panel  120 . It would be understood that the first and second panels can overlap the opposite face of the transparent panel. 
     Printing by a non-impact printer is applied to each of the panels on the face indicted by the solid arrow. Adhesive strips  125  and  126  are disposed between the overlapping panels to permanently affix the panels together to form a single sheet. Preferably, the adhesive strips are applied to substantially cover a linear area of overlap of the panels, preferably proximate and parallel to the outer edges of the transparent panel  120  to retain the integrity of the adjoined panels as a single sheet. The adhesive for attaching the panels together is well known and commercially available, examples of which are described herein. 
     A “stair-step” overlapping configuration of the subject form is shown in FIG. 11 b.  The “stair-step” overlap configuration is preferred for purposes of feeding the form through the printer (in the direction of the open arrow) to avoid nesting in the printer tray mechanism. 
     In either configuration, each of the adjoined panels is approximately one-third the length of the form. Therefore, each of the panels is slightly longer than one-third the length of the form so that they can coextensively overlap with another of the panels. In one embodiment, the transparent panel  120  overlaps approximately 0.75 inches with the first panel  110 , and overlaps about 0.5 inches with the second panel  130  (see FIGS. 11 a  and  11   b ). 
     In addition, adhesive means can be applied to an inner face of the substantially transparent panel  120  for mounting the form to a package or other item to be mailed. These adhesive strips  127  and  128  can be disposed as a single, relatively broad, continuous line or pattern. Adhesive-release material can be applied as opposing strips  129  and  131  on the inner face of first and second panels  110  and  130 , respectively. The adhesive-release strips  129  and  131  allow for removal of protective strips  122  and  123  along die-cuts  150  and  152 , respectively. Removal of protective strips  122  and  123  also removes adhesive-release strips  131  and  129  so that the form can be affixed to a package by the underlying adhesive strips  127  and  128 . 
     Perforations  160  and  162  can be formed through the substantially transparent panel  120 , positionally corresponding to die-cuts  150  and  152 , respectively (or  151  and  152  in the stair-step configuration shown in FIG. 11 b ) to provide the dual purpose of facilitating folding of the form, and to allow the top panels to be separated from the middle panel which is permanently adhered to the package. The perforations further divide the form into three separable panels, each approximately equal in size. 
     Strips of alternating adhesive and adhesive-release material can be disposed on opposing faces of panels  120  and  130 , between die-cuts  150  and  151 , which form protective strip  121  therebetween. Preferably, the alternating adhesive/adhesive-release material is disposed such that strips of adhesive having intermittent spots or areas of adhesive-release  170  is disposed on the inner face of protective strip  121 , and strips  171  of adhesive-release material having intermittent spots or areas of adhesive material are disposed on an opposing face of panel  120 . More preferably, the areas of adhesive on one panel face correspond to adhesive-release on the opposing panel. This configuration allows for controlling the amount of tack, i.e., strengthening the bond between the opposing panels, permitting the form to undergo printing operations without destroying the integrity of the form during printing operation. This alternating configuration of adhesive/adhesive-release material further allows exposure of a controlled amount of adhesive in strip  171  to adhere the outer edge of panel  110 , which is subsequently folded at perforation  162  and die-cut  152 , over panels  120  and  130  during use of the form. 
     In operational use, as illustrated in FIGS. 12 a - 12   c,  this second embodiment of the subject mailing form is printed on a single face when the form is in a flat configuration. The printed information, e.g., address information, is printed in a way so that the information is readable from one and the same direction on each panel when the form is in use, i.e., in folded configuration. Thus, the printed face of the transparent panel  120 , which is placed face down when applied to the package, is printed as a mirror image of the indicia printed on the first and second panels,  110  and  130 , respectively. This allows the indicia to be read in normal configuration, i.e., left to right, when applied to the package. The first panel  110  and second panel  120  are both printed to be read in a normal configuration when the printed face is folded over in a face-up position. 
     Preferably, the paper used for the second embodiment of the subject invention is a commercially available paper product, which can be chemically coated for making carbonless copies as described. For example, the first and second panels can be made from standard carbonless paper of appropriate thickness or weight. The transparent panel can be made from Patapar™, available from Patterson Paper Co., or preferably, is a static-free polyester which is commercially available. It is preferred to use materials which are resistant to the heat that can be generated by conventional non-impact printers. Such carbonless paper and polyester materials, including heat-resistant paper materials are commercially available. 
     The chemical coating applied to the panels allows for additional marking, e.g., signature, to be placed on the outside panel when the form is in its folded configuration, and the marking is chemically manifolded or transferred onto the other two panels. For best efficiency in achieving this for the second embodiment, the first panel  110  is coated face and back (CFB); the transparent panel  120  is coated face (CF); and the second panel  130  is coated back (CB). 
     For providing effective adherence to the form materials while retaining highly transparent properties (high-quality transparent materials typically being very smooth and therefore slick and resistant to adhesives), the carbonless transfer coating has been modified from conventionally available formulations. The modified carbonless transfer coating of the subject invention comprises zincated alkyl salicylate salt, colloidal alumina, and conventional binder, e.g., NuCoat #4168, in water. In a preferred embodiment, the novel coating can be prepared in 5 gallon batches (18,144 gms), according to the following formulation:
