ABSTRACT:
In a non-impact recording apparatus that includes a plurality of recording elements, there is provided a source of first data signals representing for each of plural pixels density, size or percentage of coverage for recording. A first look-up table memory is responsive to the first data signals for adjusting the density, size or percentage coverage of each of the pixels with a gamma adjustment related to density development by the apparatus and generates multibit gamma adjusted second data signals. A second look-up table memory generates a third signal related to a characteristic of the recording elements such as for nonuniformity correction. A process look-up table memory is responsive to the gamma adjusted second data signals and the third signals for generating fourth multibit signals relating to exposure on-times for recording pixels by the recording elements. The use of the three look-up table memories results in substantial saving in memory requirements.
