Title: Master and plate cylinder of stencil printing device and ink holding member
Inventor: MORI TOMIYA
IPC: B41L13/04
Filed: 1996-04-25
Abstract: PROBLEM TO BE SOLVED: To effectively prevent the offset from developing due to the transition of ink by a method wherein the pressure loss in the interior of a porous support is set to be a value lying within a specified range in a stencil printing master formed by pasting a thermoplastic resin film and the porous support to each other. SOLUTION: This plate cylinder 1 consists of a porous supporting plate 1b having opening parts 1a and an ink holding member 15 wound round the outer surface of the porous supporting plate 1b. The amount of ink pulled out through the bored part of a master 27 made only of a thermoplastic resin increases, since the smaller the pressure loss of the fluid in the interior of the ink holding member 15 becomes the better the passability of ink becomes. When the pressure loss in the interior of the porous support is set to be 50mmAq or more, the offset becomes smaller. When the pressure loss is set to be 24.7mmAq or more, no satisfactory image is obtained. Accordingly, the entwining ratio of the synthetic resin fibers used is selected from the group of ratios so as to set the pressure loss within the range of 5.0-23.2mm Aq.
