Abstract
There is a provided method for use with a printing system in which a second halftone pattern is selectively substituted for a first halftone pattern. The printing system preferably buffers one or more of print jobs and places each of the one or more print jobs in a print ready format. The printing system further includes a processing system in which the placing of the one or more print job into the print ready format is performed, as well as a halftone substitution subsystem for selectively operating on one or more halftone patterns which reside in one of the one or more print jobs. The one of the one or more print jobs includes the first halftone pattern and the method comprises the steps of: a) determining, with the halftone substitution subsystem, whether the first halftone pattern is renderable into a corresponding image whose image quality at least equals or exceeds a preselected image quality threshold; and b) in response to determining, with step (a), that the image quality of the corresponding image will not equal or exceed the preselected image quality threshold, substituting the second halftone pattern for the first halftone pattern, the second halftone pattern equaling or exceeding the preselected image quality threshold.
