Abstract:
An absorbent printed paper web and methods for making the printed web, the web having a visually discernible larger pattern, which can be a logo, on at least one surface formed essentially only of a paper web and a strengthening, colored bonding material. The printed web having the larger pattern can be made using the same bonding material and process used to print the background pattern. A double recrepe process using an improved Gravure roll may be used to print both logo and background. One method includes using a Gravure roll having deep depressions for printing a geometric background pattern, which can be a cross hatch pattern defining unprinting surface areas between the repeating deep depressions. The Gravure roll can also have shallow depressions in the reverse image of a logo to be printed, where the shallow depressions can have contiguous logo areas much larger than the size of the repeating deep depressions or unprinting surface areas in the background pattern. The shallowly printed regions add strength, and due to interaction with the creping roll and blade, also add bulk and softness to the finished web. The printed web can be printed with a Latex bonding material on one or both web surfaces, not requiring further web printing and compression on a surface after creping. The resulting printed web can carry a product or service logo or trademark, while being strengthened and expanded by the bonding material which also carries the logo or trademark.

Description:
RELATED APPLICATIONS 
     The present application is a continuation-in-part of U.S. patent application Ser. No. 09/999,151, now abandoned, entitled ABSORBENT WIPE HAVING BONDING MATERIAL LOGO, filed Oct. 31, 2001, herein incorporated by reference. 
    
    
     FIELD OF THE INVENTION 
     The present invention relates generally to absorbent, fibrous web materials that can include paper making fibers. More specifically, the present invention relates to paper webs strengthened with the application of bonding material patterns. The present invention can include using a double recrepe process to form colorfast, larger bonding material patterns set against repeating smaller background patterns, without requiring a subsequent printing step. 
     BACKGROUND OF THE INVENTION 
     Disposable, absorbent paper products have been developed to replace more conventional cloth products. These products include facial tissues, paper towels, towels, and wipers or wipes. The wipers or wipes may be intended primarily for use in commercial, industrial, or other harsh and/or demanding applications requiring strength. 
     For many applications, disposable absorbent paper products ideally simulate cloth in appearance, perception, and performance. Desirable physical properties include softness, strength, stretchability, absorbency, ability to wipe dry, bulk, and resistance to abrasion. The properties required of a wipe will depend on the intended use of the product. Softness is a desirable property for most absorbent paper products. End users find soft products more pleasant to handle. The softness also enables products to conform to the shape that is required by the application. Strength and stretchability are other desirable properties, particularly for products that are to be used for industrial applications. 
     It may also be desirable for a product to have good abrasion resistance, if it is to be used for wiping, scouring, or cleaning. Even for facial tissue, poor abrasion resistance can result in pilling or dusting of fibers from the tissue when handled by the consumer. Bulk is also important as it enables the paper web product to resemble cloth in feel, and also because it generally adds to softness and absorbency. 
     Some paper web properties are often inversely related. An increase in one may often be accompanied by a decrease in the other. In one example, an increase in web density or fiber concentration increases the ability of the web to wipe dry or pick up moisture, due to increased capillary action within small spaces between the fibers. Unfortunately, the increase in closeness of the fibers also decreases the space between the fibers that is available for holding moisture, thereby reducing the absorbency of the product. Strength and softness may also be inversely related. Methods which produce soft paper often result in strength reduction. This is generally true because the principal source of web strength is the inter-fiber bonds formed by the hydrate bonding processes associated with papermaking. Paper having a heavy concentration of these bonds is generally stiff. To soften the paper, it is generally necessary to reduce the stiff bonds, which often results in a loss of strength. 
     One method commonly used to reduce the stiff papermaking bonds is to crepe the paper from a drying surface using a doctor blade, thereby disrupting and breaking many of the inter-fiber bonds in the paper web. Other methods used to reduce the bonds include chemical treatment of the papermaking fibers to further reduce the inter-fiber bonding capacity. These methods generally reduce the strength of the papermaking bonds. 
     Some processes restore the strength loss by reducing the papermaking bonds, by adding bonding materials to the web. The bonding materials are capable of adding strength more than they add stiffness. In one method, the bonding material is added to the aqueous slurry of fibers and deposited on the web forming surface along with the fibers. This method, however, reduces the absorbency of the web as it fills the pores between the fibers with bonding material. 
     In another method, bonding material is applied to the web in a spaced apart, geometrically regular pattern on the web. In this method, the majority of the web surface is free of the bonding material, leaving the majority of the surface highly absorbent. As the papermaking fibers are often less than about one quarter of an inch long, it is often desirable to have the bonding material applied in a pattern, repeated at intervals less than the average papermaking fiber length. Any harshness in the bonded areas may be reduced by tightly adhering the bonded portions of the web to a creping surface and removing the web with a doctor blade, thereby finally creping the bonded portions to soften those portions of the web. 
     Attempts have been made to apply decorative or commercial messages onto paper web products, including those products strengthened with patterns of bonding material. In one method, larger, foreground patterns have been printed with ink onto paper web products. In one such method, the decorative patterns are printed with ink in a secondary process, after the paper web products have been previously printed with bonding material background patterns and creped, in a primary process. The secondary printing process requires further processing the web, including running the web through additional rolls and nips. The secondary process also requires additional capital equipment, processing time, and labor. In addition, the secondary process can compress the printed web, at least partially degrading desirable properties, such as softness and bulk, which were previously imparted by the primary process. 
     The printed ink designs made using the secondary process are often not colorfast, and may run. In some applications, wipes may be used for commercial purposes, such as cleaning products for sale, or cleaning commercial buildings for use. Industrial or cleaning solvents may be used with the wipes. The wipes, which may also be laden with aggressive solvent, can cause the logo ink color to be left behind on the wiped commercial products and commercial building surfaces. This is undesirable. 
     What would be desirable, is a method for forming large patterns onto paper web products which are also strengthened with bonding material, without causing the pattern colors to bleed over the surfaces wiped. It would be most advantageous to form the logo pattern and any background pattern in the same process, not requiring a second printing step. 
     SUMMARY OF THE INVENTION 
     The present invention includes methods of making bonded and creped absorbent paper webs. A double recrepe process can be used to print a larger, colorfast pattern on a smaller, repeating background pattern, utilizing improved Gravure rolls made according to the present invention. The present invention can provide a large pattern printed against a background pattern using the same roll and process for both. The large pattern can be a logo or brand. The present invention thus provides methods for printing a large pattern against a background pattern, without requiring a second process apart from the process used to form the background pattern. Such a second process can compress the previously creped web, and can degrade the bulk and softness added by the creping. The present invention can provide large printed patterns, without requiring printing a web surface after the surface has been creped. The present invention can provide large, colorfast patterns formed of colored bonding material. The bonding material can have pigment or colorant encapsulated in the bonding material to give a colorful, colorfast, bonding material. 
     One method includes providing a paper web having a first surface and a second surface. A first Gravure roll can be provided that has been engraved with a plurality of regular, repeating, deep depressions surrounding a plurality of non-printing, substantially flat roll regions. The first Gravure roll can further have a plurality of shallow roll depressions having a depression depth less than the deep roll depressions. The shallow roll depression regions preferably have a contiguous square area substantially larger than the non-printing roll regions defined by the surrounding regular, repeating deep depression pattern regions. A bonding material can be printed onto the web first surface by pressing the Gravure roll and bonding material against the web first surface, such that a deeply penetrating background pattern of bonding material is forced into the web by the roll deep depressions. Unprinted web regions are formed by the flat, non-printing roll regions. In some printed webs, the background pattern includes two sets of numerous parallel lines, the two sets intersecting each other to form numerous rectangular unprinted regions therebetween, forming a checked pattern. The unprinted regions thus formed have an average size defined by, and approximately equal to, the size of the enclosing four lines forming the background pattern. 
     A plurality of foreground patterns having a logo therein can be formed by the roll shallow depression regions. The roll shallow depression regions may force the bonding material into the shallowly penetrating bonding material regions. The Gravure roll thus prints onto the web first surface a series of repeating, deeply penetrating bonding material patterns having non-printed regions defined therebetween. The Gravure roll also forms a number of shallowly penetrating bonding material regions having a larger average contiguous area size than the repeating background pattern and the repeating non-printed area size. In one embodiment, the background, deeply penetrating bonding material background regions have a depth of at least about 150 percent that of the shallowly penetrating bonding material logo regions. 
     In some embodiments, the shallowly penetrating, contiguous logo areas are at least about four times the average repeating geometric background area and are at least about four times the average repeating unprinted web area. In a preferred embodiment, the shallowly penetrating bonding material region includes a visually recognizable symbol, which is more preferably a trademark or logo. In a preferred embodiment, the second surface of the web is imprinted with a deeply penetrating, regular, background pattern which can be similar to the deeply penetrating, background pattern on the first surface. In a preferred embodiment, the second surface of the web has no shallow penetrating logo or other visually discernable symbols thereon. After creping, the web is expanded or exploded due to the adhering of the bonding material to the creping drum and subsequent action of the doctor or creping blade. The web has softness and bulk imparted both near the deeply printed regions and the shallowly printed regions. The areas having the shallow printing thus have structural properties imparted in addition to any design. 
     In one embodiment, the deeply penetrating bonding material regions penetrate between about 10 percent and 40 percent of the web thickness, with the shallowly penetrating regions penetrating less than about 50 percent of the deeply penetrating regions. In some embodiments, a polymeric material is included in the bonding material. In a preferred embodiment a latex based material containing pigment is used as the bonding material. 
     The printed webs can display logos or other patterns, where the logos or other patterns consist essentially of only the bonding material and the web, not requiring any inks. The logos may be visually set off from the background, or set off from borders surrounding the logos or letters or elements forming the logos. This visual set off can be formed by a bonding material penetration depth difference between the logos, border, and/or background pattern. 
     Business methods are also within the scope of the present invention. One method includes advertising a product or service of a business entity by imprinting a trademark of that business entity on the disposable and creped absorbent paper web product using a bonding material to form the trademark. In a preferred embodiment, the bonding material used is the same bonding material used to otherwise strengthen the paper web product. The printed web product thus formed can be sold to the business entity or to a third party.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
     The following detailed description should be read with reference to the drawings, in which like elements in different drawings are numbered identically. The drawings, which are not necessarily to scale, depict selected embodiments and are not intended to limit the scope of the invention. Several forms of invention have been shown and described, and other forms will now be apparent to those skilled in art. It will be understood that embodiments shown in drawings and described above are merely for illustrative purposes, and are not intended to limit scope of the invention as defined in the claims which follow. 
     Referring now to  FIG. 1 , a process and system for applying patterned bonding material to a paper web is illustrated. A relatively standard process may be used to practice the present invention, but with the Gravure rolls being different. A paper web  20  is illustrated entering the process. Web  20  may be formed of papermaking fibers, and can have an average papermaking fiber length of about ¼ inch. In one embodiment, the fibers are Northern Soft Wood Kraft (NSWK) type fibers. In one method, the web has a basis weight of about 35–50 pounds per ream. In another method, the web has a basis weight of about 50 pounds per ream. Web  20  may be seen to have a first surface  32  and a second surface  36 . 
     Web  20  may pass through a nip formed by two rollers, a first rubber press roll  24  and a first rotogravure (Gravure) roll  26 . Rubber press roll  24  is preferably formed of a smooth rubber material and Gravure roll  26  is preferably formed of a patterned metal. First Gravure roll  26  may be seen to pass through a bonding material  30  carried within a pan  28  at a first bonding material application station  22 . First Gravure roll  26  can have a background pattern of relatively deeper impressions and a foreground pattern of relatively shallower depressions to form a logo or other design thereon. Web  20  may then optionally be passed through a drying station (not illustrated in  FIG. 1 ). After application of the bonding material  30  to a first surface of web  20 , web  20  is pressed into contact with a first creping drum  50  by a first press roll  46 . Press roll  46  causes the portions of web  20  having bonding material to adhere tightly to the surface of creping drum  50 . Web  20  is carried about creping drum  50  and then removed from creping drum  50  by application of a creping doctor blade  54 . The doctor blade imparts a series of fine lines or surface serrations to the portions of web  20  which adhered to the creping surface of creping drum  50 . The creping action also causes the unbonded, or lightly bonded, fibers in the web to puff up and spread apart, thereby forming web portions having good bulk and softness characteristics. Creping drum  50  can have any surface sufficient to bond the adhesive tightly to the drum and to thereby enable creping of the web  20  from the surface of creping drum  50 . In some methods, the surface of creping drum  50  is heated to increase the adhesion of the web to the drum and also to dry the web. In one method, a Yankee dryer is used as the creping drum. Other suitable creping drums known in the art may be used, however. 
     When the printed web hits the creping or doctor blade, the printed regions, having bonding material, stay bound together. The unprinted regions near the printed regions are pulled apart at the creping blade, leading to decreased density in the unbonded regions. In particular, regions in the center of the web thickness “explode”, gaining bulk and width, and losing density, as the nearby bonding material adheres to the creping drum and is pulled off the drum. This is true of the center web material near both the deeply printed background patterns and the shallowly printed, larger, logo patterns. 
     Web  20 , having been controllably creped, may be pulled from the creping doctor blade  54  through a pair of driven pull rolls  56  which control the degree of crepe by the difference in their speeds and the speed of the creping surface. After the first creping, web  20  may be pulled through a nip formed by a second rubber press roll  38  and a second Gravure roll  40 . Second Gravure roll  40  may be seen to rotate through bonding material  44  held within a bonding material pan  42 , all within a second bonding material application station  34 . Second Gravure roll  40  may have a plurality of deep, background pattern impressions thereon, in order to further strengthen the web. In one embodiment, only first Gravure roll  26  has a foreground, shallow logo pattern thereon. 
     After second surface  36  has been coated with a pattern of bonding material at second station  34 , the coated web is pressed to adhere against a second creping roll  52  by a second press roll  48 . After being in contact with a second creping roll  52  for a sufficient distance, a second creping doctor blade  55  crepes the second surface  36  of web  20 . Web  20  may then be pulled through an optional dryer or curing station  58  before being taken up by a take up spool or parent roll  59 . 
     Referring now to  FIG. 2A , a surface sectional portion of a Gravure roll  60  is illustrated. Gravure roll  60  has a surface region  62 . Surface region  62  may be seen to have a relatively shallow depression  64  disposed within two intermediate depth depressions  70  further disposed between deep depressions  76 . Shallow depression  64  can be used to form a relatively shallow, lower penetrating bonding material region on a web, and can be used to form a rather large logo or other indicia. Intermediate depth depressions  70  can be used to form an intermediate strength border about the logo formed by shallow depression  64 , and may not be found in many embodiments of the invention. Deep depressions  76  correspond to deeply penetrating, higher density bonding material regions, which can be used to form regular, background, geometric patterns such as long lines or stripes on the web material that form a diamond or reticular pattern. 
     As used herein, “logo”, when used within the description of making a printed web or the structure of the printed web, refers to a symbol or set of symbols which are visually discernible against a background pattern. As used herein, “density” refers to the sheet density, the weight of a section taken through the sheet within a small area which can have both bonding material and fibers. Within the width of a background line or stripe, the density is defined as being within the line or stripe width all the way through the sheet thickness, not including the unprinted space between lines. Within the letter of a logo, the density is defined as within the strokes forming the letter, not including the unprinted space between strokes. The density in regions deeply penetrated by bonding material is greater than the density in regions shallowly penetrated by bonding material, as the fibers are believed to be more tightly bound together in the regions having more bonding material. Additionally, the shallowly penetrated regions have a thicker “middle” web portion, which “explodes” or expands upon creping more than the deeply penetrated regions, which have less of a web middle to expand. 
     Shallow depression  64  may be seen to have generally a width  68  and a depth  66 . In one embodiment, shallow depression depth  66  is about 40–50 microns. Shallow depression  64  can have a width  68  sufficiently large to form a visually discernible logo or other symbol. In some embodiments, shallow depression width  68  can be between about 2 millimeters and ten millimeters. 
     Intermediate depression  70  may be seen to have a depth  72  and a width  74 . Intermediate depth depression  70  may have depth  72  being between about 60 microns and 70 microns in some embodiments. Intermediate depth depression width  74  may vary across different embodiments. In some embodiments, intermediate depth depression&#39;s width  74  may be, in effect, a dot or stippling having a very small width, for example, 0.25 to about 0.75 mm. In other embodiments, width  74  may be larger than about 1 mm. Intermediate depth depression  72  can correspond to an intermediate strength border region  65  formed about the individual symbols or letters forming a logo. Intermediate depth depression  70  may not be present in all embodiments of the invention. 
     Deep depressions  76  may be seen to have a depth as indicated at  78  and a width as indicated at  80 . In some embodiments, deep depression depth  78  may be between about 75 and 80 microns. Deep depression width  80  may be between about 0.5 mm and 1 mm in some embodiments. Deep depressions  76  may be repeated to form a regular, repeating, geometric pattern having a flat region  92  therebetween and a smallest repeating distance as indicated at  82 . Regions  92  may be referred to as “flat” even though they are, in fact, non-engraved surface points on the Gravure roll. Viewed very locally, flat regions  92  are substantially flat.  FIG. 2A , which is not to scale, includes both the background, repeating interval  82  and the shallow, logo width  68 . The logo symbol width  68  can be, for example, the width of the stroke portion of a letter. In a preferred embodiment, shallow depression width  68  is at least about two or four times the background interval distance  82 . 
     Referring now to  FIG. 2B , another Gravure roll  61  is illustrated. Gravure roll  61  is similar to Gravure roll  60 , but having a border region  63  about shallow depression  64  which differs from border region  65  of  FIG. 2A . Gravure roll  61  has border region  63  not having the intermediate depth depression of Gravure roll  60  of  FIG. 2A . 
     Referring now to  FIG. 2C , yet another Gravure roll  91  is illustrated. Gravure roll  91  has features similar to the rolls of  FIGS. 2A and 2B , but has only the background pattern associated with relatively deep depression  76  and not the shallow depression  64  or the intermediate depth depression  70 . Roll  60  may be used to print the first surface of a paper web and roll  91  of  FIG. 2C  may be used to print the second, opposite surface of the web. 
     Referring now to  FIG. 3 , a cross-section of a printed web  100  is illustrated having a first surface  102  and a second, opposite surface  104 . Web  100  corresponds to the web having bonding material applied using the Gravure roll  61  of  FIG. 2B  on a first surface  102  and the Gravure roll  91  of  FIG. 2C  on a second surface  104 . First surface  102  may be seen to have a regular pattern of high density, deeply penetrating bonding material regions  106  having a depth as indicated at  110  and a width as indicated at  111 . Second surface  104  may be seen to have a series of deeply penetrating, high density bonding material background regions  108 , which can also have a depth as indicated at  110 . Bonding regions  106  and  108  may be referred to as high density, as within a section taken through the web, there is a higher sheet density due to the bonding material and fibers being held more closely together by the bonding material within the printed regions than in the unprinted regions. This is due in part to the lesser degree of expansion in the web thickness center regions having more deeply penetrating bonding material. 
     A relatively shallowly penetrating bonding material region  112  may be seen in  FIG. 3 , formed by shallow depression  64  of roll  61 . The shallowly penetrating regions may be referred to as low density regions, as there is a lower sheet density of bonding material and fibers. Shallow penetrating bonding region  112  may be seen to have a width  68  substantially corresponding to the width of the Gravure roll shallow depression width. Shallow penetrating bonding region  112  may be seen to have a depth as indicated at  113 . The depth  110  of deeply penetrating regions  106  may be substantially greater than the depth  113  of the shallow penetration region  112  in some embodiments. In one embodiment, depth  110  is deeper than about 150% shallower depth  113 . In another embodiment, depth  110  is greater than about 200% of shallow depth  113 . 
     Depth  110  is preferably between about 10% and 40% of the web thickness. In a preferred embodiment, where deep bonding material regions  106  and  108  are directly opposite each other on opposing sides of the web, the deep bonding material regions do not connect through the web. While  FIG. 3  shows deep bonding regions  106  and  108  registered or aligned, this is not typically, intentionally, the case. As may be seen from  FIG. 3 , the regular, deeply printed background pattern regions  106  and  108  adds tensile strength to web  100 . Shallowly penetrating logo region  112  may be seen to interrupt the deeply printed background patterns. Shallowly penetrating region  112 , while having lower bonding material penetration than the background pattern regions, may nevertheless appear more visible, due to the large, continuous area relative to the narrower, albeit the deeper background bonding regions  106  and  108 . 
     Inspection of  FIG. 3  further shows a series of unprinted or non-printed regions  120  disposed between deeply penetrating regions  106  and  108 . Non-printed regions  120  may have a width of about 1 mm on each surface in some embodiments. In one view of the invention, the contiguous, non-printed space within a single non-printed region  120  may be used as a basis of quantifying the non-printed area of a surface. In some embodiments, non-printed areas  120  are defined by the surrounding background pattern formed by deeply penetrating bonding regions  106  and  108 . As may be seen from inspection of  FIGS. 2A ,  2 B, and  2 C, non-printed regions  120  correspond to substantially flat Gravure roll surface regions  92  disposed between deep depressions  76 . As may also be seen from inspection of  FIG. 3 , the shallowly penetrating bonding area  112  is substantially larger than non-printed area  120 . In one embodiment, shallowly bonded region  112  is at least about twice the average area of non-printed areas  120 . In various other embodiments of the invention, shallow penetrating bonding region  112  is at least about 4, 8, and 10 times the size of the average non-printed region  120  defined by the background pattern. 
     Regions within the web thickness may now be discussed with respect to density after creping. Middle regions  119  and  121  are disposed within the web interior, midway between the two major surfaces, with region  119  being disposed under shallowly penetrating region  112 , and region  121  being disposed near a deeply penetrating region. Another region is disposed well into the web, within a deeply penetrating region  108 . Yet another region  117  is disposed well into the web in non-printed area  120 . The fiber density in deeply printed region  115  will be high and that of region  117  low, due to the closely bound fibers and the relative lack of expansion or explosion during creping of region  115  relative to region  117 . The fiber density of region middle regions  119  and  121  will both be high, as the creping greatly expands the middle portion of the web, whether disposed near shallowly printed areas or deeply printed areas. 
     Referring now to  FIG. 4A , a first surface  102  portion of the printed web  100  may be viewed from the top. Web  100  may be seen to have the deeply penetrating bonding background pattern formed by lines  106  and having non-printed regions  120  defined therebetween. A logo, trademark or other visually perceptible symbol  130  may be seen. 
     Logo  130  may be seen to be formed of individual letters “ABC” at  132 , surrounded by an unprinted border  136 . The letter “A” may be seen to be formed of shallow penetration bonding material region  112 , as previously illustrated in  FIG. 3 . The contiguous surface areas formed by regions  112  are substantially larger than the non-printed regions  120  defined between the regularly repeating background pattern, deeply printed regions  106 . Viewed alternatively, the repeating patterns formed by the background patterns  106  may be polygons, squares, rectangles, oval, or diamonds, forming the smallest repeating units of the background in  FIG. 4A . These polygons each define an area that is substantially less than the surface area formed by the shallow penetration bonding regions, for example, forming any of the letters A, B, or C. This large contiguous area enhances visibility despite the shallow bonding depth. Moreover, the enhanced visibility of regions  112  is not at the expense of tensile strength. As used herein, “contiguous” means a substantially unbroken area as viewed with the unaided eye. In one example, the block printed letters “ABC” may have three contiguous areas, one within each letter. 
     The regular, repeating background regions  106  add tensile strength to the web by bonding a high percentage of paper-making fiber crossovers. That is, the local density of this background pattern are such that fiber crossovers are bonded to add tensile strength. Regions  112  do not penetrate the web as deeply as regions  106 . Accordingly, fiber crossovers in regions  112  are not bonded to the same depth as in regions  106 . This potential loss of tensile strength is mitigated, however, by the increased surface area bonded in regions  112 . That is, surface crossovers are bonded in regions  112  to make up for the loss of tensile strength resulting from the deeper crossovers being left unbonded in regions  112 . Although regions  112  cover a larger percentage of surface area, since regions  112  are relatively shallower, they do not add undue stiffness to the web. 
     While the shallowly printed regions may be useful for forming visually recognizable patterns, or logos, in some embodiments, there inclusion has a major structural effect. Just as the deeply printed background pattern has a structural effect. The background pattern is present not primarily for aesthetics, but for adding strength, bulk, and softness. The strength of bonding the web is a polymeric material is self evident. The bonding material also adds bulk and softness due in large part to the creping action. In particular, the bonding material can bind to the creping drum, to be creped off, greatly expanding the middle thickness of the web. Bulk and softness is increased due to the interaction of the bonding material and the creping drum and blade. The shallowly printed regions also adhere to the creping drum, and expand the web thickness as well. The shallowly printed regions, which may not have a regular pattern of unprinted regions within, can thus have different printed web properties. In particular, the same amount of bonding material present overall in a large background area can be spread out more evenly in the shallowly printed area, leaving a more of the web thickness unpenetrated, having greater capacity for expansion at the creping roll. 
     Referring now to  FIG. 4B , a leg portion  134  of the letter “A” may be seen as indicated at  134 . Region  134  is a shallow bonding material penetration region  112  as previously discussed. The contiguous, shallow penetration region  112  is preferably substantially larger than the non-printed region  120  defined between background, deeply penetrating bonding regions  106 . A border region  136  may be seen about shallow penetration bonding material region  134 . 
     Referring now to  FIGS. 4C and 4D , another embodiment of the invention is illustrated. In this embodiment, shallow penetration bonding material region  112  may be seen to include a border  136 , as previously illustrated in  FIGS. 4A and 4B . In this embodiment, however, border region  136  has an intermediate depth bonding material penetration including a plurality of intermediate penetrating depth stippling marks  138 . Stippling marks  138  form a different border region about the logo which can be used to provide an intermediate region of strength about the visible indicia or logo. 
     Referring now to  FIG. 5 , another printed web  150  according the present invention is illustrated. Web  150  may be seen to have applied thereon a background pattern formed by deeply penetrating bonding material regions  106  as previously discussed. Non-printed regions  120  may also be seen, as previously discussed. A first logo  152  may be seen, as may a second logo  154  (i.e., the assignee of the present invention). Both logos may be seen to include the shallow bonding material penetrating region  112  and a border  136 , as previously discussed. Logos  152  and  154  may be seen to indicate both a product name and a company name. In general, the present invention may be used to advertise or promote the trademarks, service marks, product names, or other messages desiring promotion. 
     Referring now to  FIG. 6 , another printed web  160  according to the present invention is illustrated. Web  160  includes a logo formed of a first word  162  and a second word  164 . Word  162  and  164  may be seen to include individual letters  166  therein. Letters  166  may be seen to be included with a substantially non-printed border region  168 . In this embodiment, however, letters  166  are formed of deep penetrating bonding material lines. Letters  166  may have a similar depth of penetration of bonding material as background pattern lines  106 . The lines in the deep penetration regions forming letters  166  may, however, be offset with respect to angle with respect to lines  106  forming the background pattern, in order to better set off the letters from the background pattern. 
       FIG. 6  thus illustrates web  160  having visibly recognizable indicia, such as logos or trademarks formed by deeply printed bonding regions formed into symbols set off from deeply printed background regions by a non-printed border region. The deeply printed background and deeply printed logo regions may, in some embodiments, have substantially the same depth of bonding material penetration and of corresponding Gravure roll depressions.  FIG. 6  also illustrates another use of the present invention. Specifically, webs according to the present invention can be used to promote desirable employee behavior by printing reminders of desired behavior on disposable wipe products. In the example of  FIG. 6 , safety is promoted by printing a safety slogan on the disposable wipe. This may be of particular use in industrial wiping applications. The desired activities or behaviors may be supplied by either the web manufacturers or by the purchasers. 
     Referring now to  FIG. 7 , another embodiment of the invention is illustrated.  FIG. 7  illustrates another printed web  180  having a regular, geometrically repeating background pattern  184  having defined corresponding non-printed regions within. A logo  182  may be seen formed on web  180 . Individual letters or symbols  186  may be seen to make up logo  182 . In this embodiment, letters  186  may be seen to be formed substantially of non-printed contiguous areas. In one embodiment, letters  186  are formed of contiguous, non-printed regions bounded by printed outline regions  188  to better define and set off the letters. Web  180  of  FIG. 7  may be made by using a Gravure roll having a regular repeating background pattern in all areas but the regions reserved for letter formations. The Gravure roll may also have depressions engraved or etched in the roll surface to better outline the letters thus formed. 
       FIG. 8  illustrates yet another printed web  200  having a logo  202  formed of a plurality of individual letters  204  surrounded by a substantially greater non-printed background area  206 . Web  200  may be used in applications requiring less strength and/or more absorbency. In some embodiments, a web such as illustrated in  FIG. 8  may incorporate stronger fibers and/or other strengthening mechanisms to compensate for the lack of bonding material in the majority of the web surface. 
     The bonding material may be any suitable bonding material, well known to those skilled in the art. A latex based, opaque, pigment containing, bonding material is used in a preferred embodiment. The bonding material preferably has a colored pigment having a different color than the web material. While the pigment color could be white, other colors are preferred. In one embodiment, in areas consisting only of background printing, the deeply penetrating bonding material covers about forty percent of the web surface, the remainder being unprinted background space. In another embodiment, in contiguous areas consisting only of logo printing, the shallowly penetrating bonding material covers about one hundred percent of the web surface within these contiguous areas. 
     Methods of doing business are also within the scope of the present invention. One method includes advertising a product or service of a business entity or other organization by printing a trademark of that business entity or other organization on the disposable bonded and creped absorbent paper web product. The printed paper web product can then be sold to the business entity, other organization, or to a third party. The printed paper web may have printed on it a symbol representing a product or service of that business entity. The symbol can be a trademark, service mark, or other visibly discernable indicia or logo representing that product, service, or business entity. 
     In one business method according to the present invention, a slogan is obtained which promotes desirable employee activity. The slogan thus obtained is printed using bonding material onto the first surface of a paper web, thereby forming a printed paper web product. The printed paper web product thus formed can be sold to a business entity to promote the desirable employee activity. In one method, the slogan promotes safety. 
     In another business method according to the present invention, a design for advertising a product or service of an entity is obtained. A disposable, bonded and creped type paper web is made having the design displayed thereon using the bonding material. The printed paper web is then sold. The paper web may be sold to the business entity. In some methods, the design is a trademark of the entity. In other methods, the design includes a logo having text representing a product or service of the entity. In one method, a trademark or service mark of the entity is reproduced in text at least as part of the design on the printed web. In another method, the trademark is represented as an unprinted area on the disposable bonded and creped absorbent paper web product. In yet another method, the trademark is represented as a bonding material low penetration region printed within a repeated geometric pattern of higher penetration pattern. The higher penetration region can form a background about the lower penetration region representing the trademark. In a preferred method, the printed bonding material region has an average contiguous printed area at least about four times that of the unprinted region defined by the high density printed background.
