WERKWIJZE VOOR HET VERVAARDIGEN VAN VLAKDRUKVORMEN MET BEHULP VAN LASERSTRALEN.

摘要

This invention relates to an improvement in the process for the production of a planographic printing form in which a carrier coated with a hydrophilic layer composed of a non-light-sensitive compound is imagewise exposed, the improvement comprising imagewise exposing the layer to laser radiation, whereby the material obtained may be used for printing in a planographic printing machine without further treatment.
