CROSS-REFERENCE TO RELATED APPLICATION The present invention is a continuation-in-part of copending application Ser. No. 708,115, .filed Feb. 26, 1968 and now abandoned.
BACKGROUND OF THE INVENTION 7 Field of the invention This invention is in the field of printing.
Description of the prior art Generally, bubble gum is sold in packages also containing trading cards. Recently, these cards have been produced with self-sticking adhesive on their back surfaces. A liner is placed on the back surface to protect the adhesive. It is desirable to accomplish printing on the top surface of the release liner. For example, the printing on the card may be in the form of a question, with the answer printed and hidden on the top interior surface of the release liner.
In order to produce the previously described product inexpensively, the printing of the liner to be release coated is accomplished with several individual printings across the width of a roll of liner. The roll of liner is laminated to the face material and the top card surface is printed. A problem occurs in locating the printing on the top exterior surface of the face material directly over the hidden printing on the release liner. This invention is a method which solves the problem and discloses the steps necessary to register the hidden printing on the release liner with the printing on the face material.
SUMMARY OF THE INVENTION This invention is a method for registering hidden printing on a release liner with a printed face material covering the liner. The hidden printing is printed on a roll of liner not having its release coating thereon with several individual printings occurring across the Width of the liner.

DESCRIPTION OF THE PREFERRED EMBODIMENT For the purpose of promoting an understanding of the principles of the invention, reference will now be made to theembodiment illustrated in the drawing and specific language will be used to describe the same. It will nevertheless be understood that no limitations of the scope of the invention are thereby intended, such alterations and further modifications in the illustrated device, and such further applications of the principles of the invention as illustrated herein being contemplated as would normally occur to one skilled in the art to which the invention relates.
My US. patent application, Ser. No. 708,115, filed Feb. 26, 1968, now abandoned, discloses face material having self-sticking adhesive on its back surface removably mounted atop -a liner. Printing exists on the top exterior surface of the face material and also on the top interior surface of the liner. For example, the printing on the top exterior surface of the face material may be in the form of a question, whereas the printing on the top interior surface of the liner would be in the form of an answer. Thus, the question may first be read, then the face material may be removed and the answer revealed. In order to accomplish. economic manufacture of the liner, it is printed on large rolls of paper or other suitable material. A roll of face material and a roll ofliner are laminated together and can be cut into individual cards.
.As a result, the printing on the release liner must be registered or located immediately under the printing on the face material. FIG. 2 shows a fragmentary view of the top interior surface of a roll of release liner. Fragment 50 of the roll of release liner has printing 54 located on its top surface which eventually abuts the adhesive back surface of the face material. Spaced equi- Y distant along the length of the roll are eyespots 55 printed co rs me th np uls s. th sixindi idual.
printed units 59 may be included between eyespots 55. The eyespots are located a -fixed distance 58 from the start of each group of six individual printed units 59. For example, eyespot 55 maybe located two'inches from the start of the first printed'line. Each eye spot 55 is proportioned on a. onetoonebasis with each display group of six units as shown in FIG- 2. f a
The first step of the. present method isto print the answer or other similar printing on the roll ofliner material shown in FIG. 2. FIG. is a block diagram of. all of the steps of the present invention.. BlQcks 111 and 112 are the first steps, namely printing-the roll of liner material. This printing is accomplished by unwinding the release liner and printing a portion thereof, and then subsequently rewinding the liner material.
FIG. 1 is a side view of a commercially available apparatus for accomplishing the printing of block 112 (FIG. 5) as shown in FIG. 2. The roll ofliner material 11 is rotatably mounted by mounting brackets 12 to apparatus 10 and is rotated in'the direction of arrow 13 'by feed roller 14 and pressureroller 15. The web of liner material is forced in thedirection of arrow 17 as roller 14 rotates in the direction of arrow 1'6. The web is then routed around guide rollers 18 and 19, where it then passes betweenimpression rollers 20 and etched roller 22 for the printing,block 112 of FIG. 5, of the liner. Roller 22 is rotatably mounted in an ink, pan 23. The exterior surface of roller 22 is etched with the desired printing to be applied to the surface of the liner material. Roller 22 is rotated into ink 24 and thenpresses against the web of liner material leaving an image there: on. The web of liner material is then driven by' impression roller 20 rotatably mounted to bracket 21 to guide rollers 25, 27 and 28 in the direction of arrow 26. The web is routed to a drying oven by rollers 29 and 31 in the direction of arrow 30, where the printed image'is subjected to forced warm air 33 from dryer 32. The web passes from dryer 32 via roller 34 in the direction of arrow 35 and is then rewound on roller 36. Brackets 37 serve as a mounting for roller 36 which is rotated in-"the direction of arrow 38. In'the present embodiment, the web is wound in such a manner so as to have the printed surface 39 facing into the center of the roll.
The liner material is then coated with silicone, block 113 of FIG. 5, by an apparatus very similar to that just described. In fact, the identical apparatus may be utilized by replacing ink 24 in pan 23 with a suitable release agent. In addition, roller 22 should be replaced with a roller having an etched surface for transferring the release agent to the board. Such a release agent is sold under the trademark Syl-Olf 23, manufactured by the Dow-Corning Corporation of Midland, Michigan. Such an apparatus as disclosed in FIG. 1 is available from Faustel, Insurporated, of Butler, Wis., under Co'ater Model No. RG 7. After the printing of the liner material has been accom-@ plished, the printed roll should be mounted to bracket 12 (FIG. 1) in such a manner that the printedsurface will contact roller 22. Thus, the release coating will be applied only to the printed surface to facilitate ease'of removal of the liner from the adhesive-backed face material. 8 I
FIG. 3 is a side view of an apparatus utilized to accomplished the lamination step of the present'method. The next step 115 (FIG. 5) of the method is to laminate or combine the printed and coated release liner with the pressure sensitive fac'e material 114; Rotatably mounted to holding fixture 83 is the silicone coated printed release liner roll 82. Face material roll 61 is rotatably mounted to bracket 62 and is unwound and routed to the adhesive coating and lamination apparatus 60. The pressure sensitive adhesive is applied to the one surface of the face material and then subsequently laminated and rolled contiguous with the silicon coated surface of rotatably vmountedto braeketsjt) andiis driven in the direction of arrow 81.
Face material roll 61 is rotatably driven in the direction of arrow 63 with the face material passing over and routed via rollers 64 and 65 in the direction of arrow 66. The face material then passes over roller 67 and appplicator roller 68 which is'rotatably suspended within pan 69 having liquid adhesive 70 surrounding the bottom portion of roller 68. Thus, as roller 68 rotates, a portion of the liquid adhesive is applied to the bottom surface of the face material passing over the roller. The adhesive backed face material is thenrouted via" rollers71, 72 and 73 to, dryer 74, which emits forced warm air 75 I thereby partially drying the adhesive. The face material is roll will not be covered by the face material. The two webs should be adjusted so that edge 51 (FIG. 2) of the release liner web is directly under one edge of the web of face material. Thus, eyespots 55 will not be coverdJApparatus 60 is produced by many companies. For example the Mayer Coater produced by Mayer Machine Company of Rochester, N.Y., may be used.
The nextstep in the present method is to cut the laminated webs into sections. FIG. 4 discloses a sheeting I apparatus '90 for cutting and stacking laminated roll 79 (FIG. 3) into individual sheets 109. Such an apparatus is available from Charles Beck Machine Corporation of Kingof Prussia, Pa., under the model name of Beck Spot Sheeter. Apparatus 90 has a photocell lamp 94 directed towards eyespots 55 (FIG. 2). The laminated roll 91 is rotatably mounted to brackets 92 and is rotated in the direction of arrow 93, passing over roller 97 and under photocell lamp 94 and photocell receiver 96 mounted on bracket 95. Rollers 98 are provided to guide the web towards cutter 100. Cutter blade 100 is positioned across the top of the laminated web and is attached on its ends to two drums 101 rotatably mounted to the frame outside the edges of the laminated web. Drums 101 are rotated in the direction of arrow 102 by motor 104 attached by bracket 103. Motor 104 is time sequenced by photocell receiver 96. That is, photocell receiver 96 reads the passing eyespots printed on the release liner and sequences blade 100. to cut across the laminated web at every eyespot. The severed laminated sheet then passes across'the rollers 105 in the direction of arrow 106 falling onto stack 109. Guide rails 108 are positioned so as to cause the severed laminated sheet to fall in the direction of arrow 10'] thereby forming stack 109 Block 116 of FIG. 5 illu'strates'the cutting of the laminated sheet ac complished by the apparatus shown in FIG. 4.
The severed laminated sheets are then trimmed 117 along their length and the top exterior surface of the face material is printed 118 with the desired question or other similar printing. Any standard sheet feed printing process, such as letterpress, offset lithography, silk screen, and gravure, may be utilized to accomplish printing step 118. The hidden printing on the release liner is located a known distance from the top edge of the severed laminated sheets since the severing occurred along a line defined by eyespots 55. Thus, printing 118 must be located with respect to the top edge of the severed sheets in order'to register or locate the printing of the face material with the hidden printing on the release liner. The last step in the method is to out these printed laminated'sheets into individual labels 119 by cutting along the lines 52 and 53 shown in FIG. 2.
It will be obvious from the above description that the present invention provides a method of producing hidden registered printing. It will be further obvious from the above description that the present method of producing an improved adhesive product may be accomplished relatively inexpensively. In addition, it will be obvious that the present method may be utilized to produce a paper and paperboard novelty which can present certain information and hide related information until it is desired that the related information be exposed.
While the invention has been illustrated and described in detail in the drawings and foregoing description, the same is to be considered as illustrative and not restrictive in character, it being understood that only the preferred embodiment has been shown and described and that all changes and modifications that come within the spirit of the invention are desired to be protected.
