OFFSET PRINTING WEB (VARIANTS), COMPRESSIBLE FABRIC, COMPOSITE MATERIAL, METHOD OF MANUFACTURE OF COMPRESSIBLE FABRIC, OFFSET PRINTING WEB, COMPOSITE MATERIAL Russian patent published in 1998 - IPC

FIELD: printing. SUBSTANCE: multilayer glued compressible offset web used for offset printing has in succession: the first compressible layer of fabric, compressible elastomer layer, at least two additional layers of fabric positioned above the compressible elastomer layer, elastomer sublayer and elastomer printing face coating applied without any use of solvents and having the surface profile, adapted to decrease of the increase of the point size at an increase of detachability of printing material. At least the lowest fabric layer includes a protective coating used to prevent flowing of printing inks, water and/or solvents in offset printing web. Besides, the fabric layer, like the compressible layer, at least partially is coated with flong having a great number of closed cells dispersed in it, formed, for instance, with the aid of blowing agents or by introduction of a great number of expanded or expandable microspheres to it. Products that can be formed out of this composite structure include spacers, packaging materials, flexible diaphragms or printing webs. EFFECT: improved physical properties of web, compressible fabric and composite material. 87 cl, 4 dwg
