Method of compensating color tone for color printer and color printer having color tone compensator

摘要

The color printer is disclosed, including ways to compensate for the color tone of a color printer and a color tone compensation. Hue compensation method according to the invention, a) obtaining a standard of color tone reproduction curve (Reference Tone Reproduction Curve, RTRC) to be printed based on the printing environment, b) the sample patterns of the one or more tones at a predetermined target medium forming step, c) formed sample pattern of use by area-specific tonal reproduction curve (Sectional Tone reproduction curve, STRC) and formation phases and d) area-specific tonal reproduction curve (STRC) and the reference tonal reproduction curve (RTRC) and the to compensate for the deviations of area tone reproduction curve to reduce the specific area (sectional deviations) (STRC) includes the step of adjusting one or more print parameters. According to the present invention, there is robust to disturbances and noise, there is provided a hue compensation method that can be approximated by a complex mathematical area tone reproduction curve without having to go through the operation (STRC) and the reference tone reproduction curve (RTRC).
