Embodiment Construction

[0037] An advantageous embodiment of the reusable printing plate according to the invention and the pattern formation of the reusable printing plate according to the invention will be described below by means of the example of a naturally oxidized titanium surface and n-octadecane-phosphonic acid. An advantageous embodiment of the method, wherein the universality is not limited in terms of hydrophilic-lipophilic organic compounds and in terms of metal oxide surfaces.

[0038] Figure 1 shows a flow chart of an advantageous embodiment of the method according to the invention for forming graphics of a reusable printing plate according to the invention. Samples with a titanium surface are available from the company "Goodfellow". In order to firstly decontaminate the titanium surface to be treated, it is irradiated with light in the ultraviolet wavelength range. Step 10 of the method of preparing a reusable printing plate comprises applying a hydrophilic-lipophilic organic compoun...

Abstract

Presented is a reusable printing form including a printing area that has a metal oxide surface, in particular a native oxidized titanium surface, which is treated with at least one amphiphilic organic compound whose polar region has an acidic character. In an advantageous embodiment, n-heptadecanyl hydroxamic acid {CH3-(CH2)16-C(O)-NH-OH} and / or n-octadecanyl phosphonic acid {CH3-(CH2)17-P(O)-(OH)2} is used. Also described is a method for imaging a reusable printing form. The reusable printing form can be used for offset printing.

Description

technical field [0001] The invention relates to reusable printing plates, especially printing plates with one printing surface for offset printing. The present invention also relates to a pattern forming method of a reusable printing plate. Background technique [0002] Printing plates are used in the printing mechanism of a printing press for applying a predetermined printing pattern, predetermined theme or image to printed material. Typical printing materials are paper, cardboard, cardboard, organic polymers, fabric or the like. In this case mainly printing plates are used, on whose printing surface (ie on a part of the surface of the printing plate) the pattern to be printed is permanently applied, formed or drawn. This printed version can only be used once. Reusable printing plates, especially printing plates that can draw multiple times or form graphics multiple times, are desirable for a variety of reasons. In other words, it is of interest that the printed surface...
