Abstract
Disclosed is a method, system, and program for generating a table for enhancing the print quality of input raster pel data. An output value is generated for different patterns of pel data. Each output value indicates a sub-pulse width power to charge a sub-pel region within a pel and position information indicating the justification of the sub-pel region within the pel. A look-up table is formed from the generated output values that enhances print quality.

A method for generating a table for enhancing the print quality of input raster pel data, comprising:
- generating an output value for different patterns of pel data, wherein each output value indicates a sub-pulse width power to charge a sub-pel region within a pel and position information indicating a justification of the sub-pel region within the pel;
- and
- forming a look-up table from the generated output values that enhances print quality.
A system for generating a table for enhancing print quality of input raster pel data, comprising:
- means for generating an output value for different patterns of pel data, wherein each output value indicates a sub-pulse width power to charge a sub-pel region within a pel and position information indicating a justification of the sub-pel region within the pel;
- and
- means for forming a look-up table from the generated output values that enhances print quality.
An article of manufacture for use in generating a table for enhancing print quality of input raster pel data, the article of manufacture comprising at least one computer program capable of causing a processor to perform:
- generating an output value for different patterns of pel data, wherein each output value indicates a sub-pulse width power to charge a sub-pel region within a pel and position information indicating a justification of the sub-pel region within the pel;
- and
- forming a look-up table from the generated output values that enhances print quality.
A computer-readable transmission medium including at least one look-up table data structure used for enhancing the print quality of input raster pel data, comprising:
- an output value for different patterns of pel data, wherein each output value includes:
- (i) a sub-pulse width power to charge a sub-pel region within a pel, and
- (ii) position information indicating a justification of the sub-pel region within the pel.
