Abstract
Methods and systems for automatically generating printer profiles for color printers to evenly distribute translation errors between device color spaces are described. Since the color spaces of source devices, e.g., monitors and scanners, differs from that of destination devices, e.g., printers, translation is necessary. As some colors may be available to source devices which are not available to destination devices, this translation is inherently imperfect. Moreover, conventional techniques apply imperfect models of the color space which further skew the results. According to the novel methods and systems described herein, a nonlinear regression technique is applied in an automated system which reduces perceptual changes.
