Patent ID: 8493627

Claim:
A method for digital screening of a halftone image, which comprises the steps of: providing a computer for performing the method, the computer performing the steps of: providing a first screen having an arbitrary desired screen width, an arbitrary desired screen angle, and assigned X 1 Y 1 addresses; reading out and comparing a first threshold value matrix of a second screen with color values of the halftone image, the second screen having a given screen width, a given screen angle, and assigned X 2 Y 2 addresses; during a reading of threshold values, determining an error D between the XY addresses of the second screen and the first screen; providing at least one second threshold value matrix having assigned X 3 Y 3 addresses, the X 3 Y 3 addresses of the second threshold value matrix being displaced by a factor 1/B in relation to the X 2 Y 2 addresses of the first threshold value matrix; and reading out the second threshold value matrix as soon as the error D exceeds a predefined limiting value.
