Abstract:
1. A method of printing a representation on a print medium of an array of contiguous print data pixels comprising a plurality of parallel rows of contiguous print data pixels, the method comprising the steps of: processing print data from said array of contiguous print data pixels such that it is distributed over an array of super pixels, each super pixel having a print level, according to a distribution function such that the print level of each super pixel is calculated based on a print data contribution from at least two print data pixels and each print data pixel contributes print data to the calculation of print levels for at least two super pixels; and forming print pixels on the medium such that each print pixel receives a print contribution from N (where N is an integer greater than 1) super pixels, wherein said processing step comprises distributing the print data for each of said rows of print data pixels over a respective group of N superimposed rows of contiguous super pixels, and wherein each of said superimposed rows of super pixels extends in a row direction and each row within a group of N rows of super pixels is offset in said row direction with respect to each of the other superimposed rows in that group.
