ABSTRACT:
A method and apparatus for processing a screened separation comprises an analyze scanner for scanning the separation at a resolution higher than the screen ruling to generate a binary value for each high resolution pixel of the separation; a processor for generating signals representing single values for respective blocks of the high resolution pixels from the binary data in the blocks; and a descreening system to which the signals from the processor are fed, the descreening system generating signals representing a descreened version of the original separation.
