ABSTRACT:
A printer driver employs multi-level dither to limit the size of a look-up table required for its color-correction operation. To suppress some of the resultant artifacts, a filter operation precedes the half-toning operation used to produce the printer input signal. The computation cost of the filter operation is modest because it uses an infinite-impulse-response filter.
