Abstract:
A printer configured to adjust gloss appearance of images includes a marking engine configured to render an image on a substrate from input image data; and a controller configured to: (i) correlate a minimum luminance value to be used by the printer based on a gloss selection; (ii) determine a black point compensation function based on the correlated minimum luminance value; and (iii) adjust luminance values for input image data using the determined black point compensation function. A method to adjust gloss appearance of images is also provided.
