Noise reduction in toner prints

摘要

Methods for determining toner color images are provided in which fluorescent toner is used create light in a fused toner mass that reduces the appearance of noise in a noise evident portion of the fused toner mass.

主权项

1. A method for determining toner color images, the method comprising:
obtaining image data and printing instructions for printing the image data; determining a pattern of target colors based upon the image data and the printing instructions and a color gamut that can be formed using a predetermined combination of reflective toner colors; generating a plurality of reflective toner color images for combination in register to form the pattern of target colors; identifying at least one noise evident portion in the pattern of target colors where any unintended density variations will create visual artifacts in the print; generating a fluorescent toner color image that when printed using a corresponding fluorescent toner will generate a diffuse fluorescent color light that reduces the extent to which noise induced variations in density in the noise evident portion are observable; and, adjusting the plurality of reflective toner color images so that the reflective toner color images combine with the fluorescent color image to form the target color image.
