DRUCKFORM, DRUCKFORMZYLINDER UND VERFAHREN FÜR EINEN NASSOFFSETDRUCK

摘要

The printing plate (12) is formed of upper (15) and lower (14) layers of hydrophilic material on a carrier (13). The upper layer top (image carrying) layer is wetted through ducts (5) from inside the plate cylinder (2). The rate at which the wetting agent can flow through the plate is reduced abruptly at the boundary between lower and upper layers. The lower layer can be formed of a mat of stainless steel metal fibres and the upper by plasma spraying
