Abstract:
A method for optimizing half-tone representation in electrophotographic printer or copier apparatuses, comprising the steps of:applying a raster toner mark on a surface.,determining an optical density of said raster toner mark, determined integrally over a surface,modifying at least one of a bias potential applied to a photoconductor of the electrophotographic printer or copier apparatus and a toner concentration,said raster toner mark including repetitions of macropixels, said macropixels each being at least one dimension larger than a micropixel raster dimension, and being smaller than 0.5 mm, and said macropixels each including at least one micropixel that is not inked with toner, as well as at least one micropixel that is inked with toner.
