ABSTRACT:
Disclosed is a method, system and program product for performing multiple-pel print quality enhancement (PQE) using amplitude modulation. A determination is made of an adjusted peak amplitudes value of each pel of an image. At least two adjacent pels are then grouped together and a determination is made of a peak amplitudes value that will serve as a gray amplitude value for each pel in the pel group. Also determined is position information indicating the alignment of the peak amplitudes within the combined area. The combined peak amplitudes and position information is sent as input to an amplitude modulator operating at a speed equal to the video data rate of the printer divided by the number of pels for which the peak amplitudes data is combined.
