METHOD OF COMPENSATING COLOR TONE FOR COLOR PRINTER AND COLOR PRINTER HAVING COLOR TONE COMPENSATOR

摘要

A tone compensation method for a color printer and a color printer having a tone compensator are provided, wherein the method includes the steps of (a) acquiring a reference tone reproduction curve of print colors based on a printing environment, (b) forming sample patterns for one or more colors on a predetermined object medium, (c) forming a sectional tone reproduction curve by using the sample patterns, and (d), adjusting one or more print variables to compensate the sectional tone reproduction curve in order to reduce sectional errors between the reference tone reproduction curve and the sectional tone reproduction curve. Accordingly, it is possible to provide a tone compensation method capable of compensating for a sectional tone reproduction curve to approximate a reference tone reproduction curve without complicated mathematical calculations, and which is substantially unaffected by external disturbances and noise.
