A method of making a photopolymer sleeve blank for use in flexographic printing is provided which includes providing a base sleeve, applying a cushion layer over the base sleeve, applying an optional barrier layer over the cushion layer, and applying a photopolymer layer over the barrier or cushion layer. The method provides a sleeve blank having an integral cushion layer and eliminates the need for a back exposure step.

Method of making a photopolymer sleeve blank having an integral cushion layer for flexographic printing

A sleeve for a print cylinder comprising a fiber reinforced, thin-walled material and having a seamless surface ready to be covered with a surface material. The sleeve may be used in flexographic printing, either as a support for photo-polymerized printing plates or rubber layers. The sleeve has the advantages of having low manufacturing cost and providing the necessary heat resistance to withstand rubber vulcanization temperatures. The sleeve is also airtight, and remains properly positioned during printing operations.
