Abstract

In order to improve printing precision for a pattern of differing line widths, the present invention provides an offset printing machine for transferring and forming a pattern from a first intaglio (101) and a second intaglio (102) on a substrate (1) on a substrate table (115) via a single blanket cylinder (121).

Description

Intaglio offset printing machine

The present invention relates to an intaglio offset printing machine.

In the printed electronics (PE) field, application of an intaglio offset printing press is being studied. For example, in a flat bed type in which a sheet-like base material is placed on a table and printed, ink is applied to the plate cylinder while rotating the plate cylinder having a sleeve intaglio on which a pattern such as a wiring pattern is formed. The ink corresponding to the pattern of the sleeve intaglio of the plate cylinder was transferred onto the blanket of the blanket cylinder by supplying and rotating the blanket cylinder around the blanket while being in contact with the plate cylinder. Then, by rolling the blanket cylinder on the base material of the table, the ink on the blanket of the blanket cylinder can be transferred and printed on the base material ( For example, see Patent Document 1 below).
