Abstract
With the method according to the invention for producing a printing plate, in particular for flexoprinting, a layer of a curable elastomer is applied to a carrier (15) with a cylindrical surface area (26), subsequently the elastomer layer is cured to an essentially cylindrical endless printing form blank and possibly ground to a cylindrical peripheral form or processed otherwise, and afterwards the printing form blank (33) is separated along a line which is essentially parallel to the axial direction of the carrier and the printing plate produced in such a manner
Claims21
Method for producing a printing plate in particular for relief printing, characterized by the following steps:
- a) applying a layer (32) of a curable elastomer onto a carrier (15) having a cylindrical surface area (26);
- b) curing the elastomer layer on the carrier (15) into an essentially cylindrical, endless printing form blank (33);
- c) separating the printing form blank (33) along a section line essentially parallel to the axial direction (22) of the carrier;
- and
- d) withdrawal of the printing plate (11), which is produced in such a manner, from the surface area (26) of the carrier (15).
Printing plate for relief printing, in particular for flexoprinting with a lower carrier foil or plate (27) and an elastomer layer (32) of silicone polymer, silicone fluorine polymer or polyurethane applied thereto which is processed, in particular ground, after its application to the carrier foil or plate and curing for forming an even surface.
