Patent ID: 8368963

Claim:
A method of exposing a printing form, which comprises the following method steps: providing a matrix having device-dependent image information on a computer for supplying data to a printing form exposer; transforming the matrix having device-dependent image information in a matrix manipulation device into a corrected matrix having device-dependent image information, and thereby: defining a first part of a transformation rule for producing the corrected matrix in a first zone of the matrix as a function of an area coverage of the first zone; defining a second part of the transformation rule for producing the corrected matrix in a second zone of the matrix, which is different from the first zone, as a function of an area coverage of the second zone; the area coverage in the first zone and the area coverage in the second zone being different from each other; and exposing the printing form in a printing form exposer with the image information according to the corrected matrix.
