System and method for adjustment of coverage parameters for different colors in image data

摘要

A method of operating a printer includes reducing a first plurality of coverage parameters in a first continuous tone (contone) pixel by a predetermined amount if a combination of at least two of the coverage parameters is below a predetermined threshold and reducing a second plurality of coverage parameters in a second pixel by a smaller amount if the combination of coverage parameters in the second pixel is greater than the predetermined threshold. The method further includes generating half-tone image data from the first and second pixels and forming printed marks corresponding to the first and second pixels on an image receiving surface.

1. A method of operating a printer comprising:
identifying a first plurality of coverage parameters for a first pixel of continuous tone (contone) image data, each coverage parameter corresponding to one color separation in a plurality of color separations; reducing each of the first plurality of coverage parameters by a first amount in response to a combination of at least two of the first plurality of coverage parameters being below a predetermined threshold; identifying a second plurality of coverage parameters for a second pixel of the contone image data, each coverage parameter in the second plurality of coverage parameters corresponding to one color separation in the plurality of color separations; reducing each of the second plurality of coverage parameters by a second amount, the second amount being less than the first amount, in response to a combination of the at least two of the second plurality of coverage parameters exceeding the predetermined threshold; generating half-tone image data corresponding to the first pixel and the second pixel; and operating a marking unit with reference to the half-tone image data to form marks corresponding to the first pixel and the second pixel on an image receiving surface.
