Attorney Docket No: 3255 PRINTING BLANKET WITH IMPROVED RELEASE CHARACTERISTICS Thomas C. DiPerna The present invention relates to printing blanket construction which provides a non-uniform, randomly microstructured printing surface. The printing surface is prepared by (a) covering an unvulcanized printing blanket outer surface with a release paper having a Gloss (60.degree.) from about 2 to about 4 and a release from unvulcanized rubber at 20.degree.C less than about 20 g/25mm, (h) vulcanizing the paper covered surface to cure the outer surface, and (c) removing the paper to expose a printing surface with a perthometric roughness of from about 4 um to about 25 um. The resulting printing surface provides improved print quality, improved ink release and a low degree of tack toward printer paper. The present invention also relates to the method of preparing the above printing blanket composition. 2778P
