Embodiment Construction

[0027] Features corresponding to or identical to each other in the figures are provided with the same reference numerals.

[0028] figure 1 The flow of an embodiment of the method according to the invention is shown schematically. In a method step 100 (preparation), a titanium printing plate 110 is prepared, which has a support 120 made of titanium (Ti) with a support made of titanium dioxide (TiO 2 ) (alternatively composed of TiOx, ZrO 2 , Al 2 O 3 , other metal oxides or high-quality steel), the titanium printing plate also has a coating with a layer 140 of amphiphilic molecules on this surface 130 . By coating the amphiphilic molecules, the surface of the printing plate 110 has a defined uniform hydrophobicity.

[0029] Before the first printing, when the printing plate 110 is prepared for the first time, the printing plate can be pre-cleaned with acetone and cleaned with UV rays in a first step and activated (for example: using a strength of 45 mW / cm 2and a xenon ex...

Abstract

The present invention relates to method of treating printing plate after printing for re-imaging, and the printing plate has one carrier for applying amphoteric molecules. Before reuse in printing, amphoteric molecules are applied to the printing plate to clean off printing ink basically for re-imaging.

Description

technical field [0001] The present invention relates to a method for post-printing processing of a reimageable printing form, wherein the printing form has a carrier to which amphiphilic molecules are applied, and for a new printing, during the reimaging process, the printing ink is washed off and applied amphiphilic molecules. The invention also relates to a wet offset printing method provided with the above-described method, wherein a reimageable printing plate is used which has a carrier to which amphiphilic molecules are applied. [0002] Furthermore, the invention relates to a device for post-printing processing of a reimageable printing plate, wherein the printing plate has a carrier to which amphiphilic molecules are applied, wherein the device has a device for washing off the printing plate of A cleaning unit for printing ink and a unit for applying amphiphilic molecules to the printing plate; the invention also relates to a machine for processing substrates, in parti...
