Abstract

A printing method for a printer having a printhead with a plurality of print elements and capable of printing a binary pixel image, the method comprising the steps of:
a) locating defective print elements,
b) determining a camouflage area in the vicinity of pixels that would have to be printed with the defective print elements, and
c) camouflaging defective print elements by modifying image information in said camouflage area,
characterised in that the camouflaging step is incorporated in a halftoning step, in which error diffusion is used for creating said binary pixel image, and comprises a step (S104; S204) of modifying an error propagation scheme for the camouflage area.
