- Requirement: high bond strength and resistance to solvents
Demounting of plates
When printing is finished, the plate must be easily removable from the tape. During demounting, the plates must release easily without stretching or tearing, and adhesive residue must not transfer to the back of the plate.
- Requirement: easy removal of plate without adhesive residue
Removal of tape
It should also be possible to easily remove the tape from the sleeve; the sleeve must be free of residues in order to minimize the time required for cleaning work and for the preparation of the next printing job.
- Requirement: easy tape removal without adhesive residue
So how can these highly conflicting requirements be reconciled?
We offer a new patented tape system which is based on the tesa SNAP-ON technology, a solution which can solve these problems:
- easy repositioning of the plate
- secure bonding of the plate
- easy plate demounting
- easy tape removal
How does the adhesive system work?
The new patented acrylic-based adhesive can be illustrated using the SNAP-ON model for each process step. During the mounting process, the plate lies only lightly against the adhesive. Low tack allows the optimum print register to be found quickly and easily. When the plate is rolled on, a procedure we recommend be performed using a rubber roller, the plate literally “snaps” into the adhesive. This generates strong bond strength. During the printing process that follows, this ensures reliable bonding of the plate and prevents its edges from lifting. Result: This can reduce machine downtime and increase productivity. When the plate is demounted following printing, it is free of tape residue. The faster the plate is demounted, the more easily it separates from the tape. You can almost hear it “snap out” again.
