Abstract
The invention relates to a process for producing a printing form, in which a covering layer (5) is applied to a first radiation-sensitive layer (4) arranged on a carrier (1), the applied covering layer (5) is structured in accordance with a pattern to be printed, in order to form an irradiation mask (5′), and the radiation-sensitive layer (4) is irradiated and developed. In this way, in the production of printing forms, an irradiation mask (5′) can be applied very precisely in accordance with a pattern to be printed later.
Claims40
A method for producing a printing form, comprising the steps of:
- applying a first radiation-sensitive layer on a carrier;
- applying a covering layer containing at least one of fine light-absorbing particles, fine light-reflecting particles, black carbon, fine metal particles, pigments, and radiation-absorbing chemicals to said first radiation-sensitive layer;
- applying a structuring mask to said covering layer, wherein the step of applying the structuring mask includes
- applying a second radiation-sensitive layer to said covering layer,
- irradiating said second radiation-sensitive layer in accordance with a predetermined pattern, and
- developing said second radiation-sensitive layer after the step of irradiating said second radiation-sensitive layer for structuring said structuring mask in accordance with said predetermined pattern;
- and structuring said covering layer using said structuring mask, wherein the step of structuring said covering layer includes
- removing uncovered portions of said covering layer in order to form a radiation mask in accordance with said predetermined pattern,
- irradiating said first radiation-sensitive layer, and
- developing said first radiation-sensitive layer.
