ABSTRACT:
In a method of preparing a screened reproduction, a laser beam modulated in an on-off manner scans a film or plate comprising a substrate resistant to the laser beam and a two-layer coating which is removed by the laser beam, after which correction is carried out by subjecting the image-defining coating dots to the action of a chemical agent. The coating layer adjacent the substrate is attacked by the chemical agent but the overlying coating layer is resistant to the chemical agent and protects the top surface of the first layer, permitting a reduction of the size of the coating dots without a reduction in their thickness.
