Embodiment Construction

[0027] Corresponding or identical features are provided with the same reference signs in the figures.

[0028] figure 1 The sequence 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 carrier 120 made of titanium (Ti), which has a titanium dioxide (TiO 2 ) (alternatively by TiOx, ZrO 2 、Al 2 o 3 , other metal oxides or high-grade steel), the titanium printing plate also has a coating with a layer 140 of amphiphilic molecules on the surface 130 . By coating the amphiphilic molecule, the surface of the printing plate 110 has a certain uniform hydrophobicity.

[0029] Before the first printing, when the printing plate 110 is prepared for the first time, the printing plate can be pre-washed with acetone and cleaned with UV rays and activated in a first step (for example: using 2and a xenon excimer UV emitter at 172 nm; use approximately 10 minutes). In t...

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 invention relates to a method for post-printing processing of a reimageable printing plate, wherein the printing plate has a carrier to which amphiphilic molecules are applied, and for a new print the printing ink is washed off during the reimaging process and applied Amphiphile. The invention also relates to a wet offset printing method provided with the above method, in which a reimageable printing form 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 cleaning off the printing plate A washing unit for printing ink and a unit for applying amphiphilic molecules to the printing plate; the invention also relates to a machine for processing printing substrates, in particular an offset printing p...
