摘要

FIELD: offset printing. SUBSTANCE: multilayer bonded compressed printing offset cloth 10 used in offset printing includes first compressed layer of fabric 12, compressed elastomeric layer 24, at least two additional layers 32, 34 of fabric positioned above compressed elastomeric layer, elastomeric sublayer 44 and elastomeric printing face coating 46 applied without usage of solvents and having profile of surface tailored to diminish increase of size of dot with enhanced detachment of printing material. Lowest layer of fabric 12 includes protective coat to prevent leaking of printing inks, water and/or solvents into printing offset cloth which may in opposite case lead to swelling and segregation of (different layers. In addition both layer of fabric and compressed layer are at least partially covered by material of matrix 20 having assemblage of closed cells 26 formed with the aid of pore formers dispersed into it or by injection into it of assemblage of expanded or capable of expansion microspheres. Articles that can be formed from this composite structure includes gaskets, packing materials, flexible membranes or printing offset cloth. EFFECT: expanded range of products manufactured in compliance with invention. 1 dwg
