ABSTRACT:
A method of making-up offset printing cylinders having lock-ups positioned in gaps in the cylinders by use of a two piece system involving adhering a compressible printing element to the cylinder with at least one edge extending into the lock-up gap, trimming the edge extending into the lock-up gap, thereafter pulling a non-compressible printing element carrying the printing ink indicia receptive working surface taut over the compressible printing element and securing the ends of the non-compressible printing element in the lock-up under tension. The two piece system involves separating the relatively thick compressible portion of the offset printing blanket from the relatively thinner ink transfer surface of the offset printing blanket. Also a separate embodiment with pressure sensitive adhesive securing the two piece system together and not limited to offset printing cylinders, product and method.
