Abstract

Techniques are disclosed for depleting raster data to allow printing of the depleted raster data on a grid that corresponds to the resolution of the undepleted raster data with a printed dot size that is larger that would otherwise be utilized with the undepleted raster data and to achieve faster ink dry time. Also disclosed is a technique for up scaling raster data at a particular resolution (e.g., 300 dpi) to a higher resolution in such a manner that expanded data includes a greater number of dot producing pixels to compensate for a dot size that is larger than the dot size that is appropriate for the higher resolution, and does not require horizontal depletion for printing with such dot size. This allows raster data at a particular resolution to be combined with higher resolution rasterized vector data for printing in accordance with the enhanced mode of operation.
