ABSTRACT:
There is disclosed a multi-layer tape system, of the type disclosed is Castelluzzo application Ser. No. 930,700, U.S. Pat. No. 4,182,789, for applying register marks or other symbols to aligned art-work sheets used in the graphic arts field. In a two-layer system, each of two superimposed tapes has aligned markings thereon. A weak adhesive secures the two tapes together, and the two outer surfaces are coated with a strong adhesive. In a four-layer system, a separator is disposed between a pair of two-layer systems; the separator has holes therein so that the two tape systems can adhere to each other and remain in alignment, contact being made in the regions of the holes. The relative adhesive strengths maintain the system integrity prior to use while also permitting tape sparation during use. Instead of using clear tapes and printed markings as in the Castelluzzo system, opaque or colored tapes with punched markings are employed. This greatly simplifies manufacture because there is no need to align pre-marked tapes during the lamination step; the registration markings are punched after lamination. Color contrast is achieved by use of the opaque or colored tapes.
