Abstract
Abstract There is disclosed a multi-layer tape system for applying register marks or other symbols to aligned artwork sheets used in the graphic arts field. In a two-layer system each of two superimposed clear tapes has aligned markings printed 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 separation during use.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
200 words
A multi-layer graphic arts tape system comprising a first clear tape having an adhesive coating on a first surface thereof, a second clear tape having a first surface in facing relationship with the second surface of said first tape and having an adhesive coating on the second surface thereof, a separator strip having a first surface in facing relationship with said second surface of said second tape, a third clear tape having an adhesive coating on a first surface thereof in facing relationship with the second surface of said separator strip, said separator strip containing holes therein for allowing said adhesive coatings on said second surface of said second tape and said first surface of said third tape to adhere to each other in the regions of said holes, an adhesive disposed between said second surface of said first tape and said first surface of said second tape and having a bonding force which is less than that provided by the adhesive coating on each of said first and second tapes when each of said tapes is applied to an application surface, and a plurality of markings on each of said first, second and third tapes aligned with each other.
Claim 2
Dependent Claim
200 words
A multi-layer graphic arts tape system comprising a first clear tape having an adhesive coating on a first surface thereof, a second clear tape having a first surface in facing relationship with the second surface of said first tape and having an adhesive coating on the second surface thereof, a separator strip having a first surface in facing relationship with said second surface of said second tape, a third clear tape having an adhesive coating on a first surface thereof in facing relationship with the second surface of said separator strip, said separator strip containing holes therein for allowing said adhesive coatings on said second surface of said second tape and said first surface of said third tape to adhere to each other in the regions of said holes, an adhesive disposed between said second surface of said first tape and said first surface of said second tape and having a bonding force which is less than that provided by the adhesive coating on each of said first and second tapes when each of said tapes is applied to an application surface, and a plurality of markings on each of said first, second and third tapes aligned with each other.
