ABSTRACT:
Negative correction of gravure printing plates by filling undesirable depressions in the printing layer of the gravure printing plate with a correcting agent is carried out by a method in which the correcting agent used is a pasty material which is viscoplastic at room temperature and is based on a dispersion of a solid, highly fluorinated olefin polymer powder in an inert, sparingly volatile, organic dispersing liquid.
