ABSTRACT:
A sheet material for mounting flexible printing plates to the drum of a printing press includes a base film, a flexible foam uniformly coated on the base film, and a pressure sensitive adhesive coated on both the base film and the foam. The cohesion of the base film and the foam, the adhesion of the base film to the foam, and the adhesion of the adhesive to the base film and the foam is greater than the adhesion of the adhesive to the flexible printing plate and to the drum of a printing press. When the sheet material is removed from the printing plate and the drum, the foam, the base film, and the adhesive remain an integral sheet. A method for preparing and using the sheet material is also disclosed.
