Abstract
The present invention relates to a printing blanket comprising an inner multilayer spiral wound polymeric sleeve, wherein the sleeve comprises between 2 and 5 layers that are affixed to one another with an adhesive, the winds overlay one another to form the multiple layers, the gap between adjacent edges of each ribbon are less than 0.2 inches apart as measured axially, the total sleeve thickness is between 0.006 to 0.0028 inches, and the layers are formed either from a single continuous ribbon or a plurality of continuous ribbons of polymeric material. The adjacent edges of the ribbon may alternately overlay axially in an amount such that relaxation during curing results in non-overlapping edges.
