Abstract:
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 includesapplying a second radiation-sensitive layer to said covering layer,irradiating said second radiation-sensitive layer in accordance with a predetermined pattern, anddeveloping 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 includesremoving 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, anddeveloping said first radiation-sensitive layer.
