Patent ID: 8743439

Claim:
A method for generating an optimized printer calibration by using a printer, the method comprising: a) printing with the printer a first test chart containing finely graduated ascending color fields for each primary color between 0% and 100%; b) limiting, with a processor, colorimetrically for each primary color a maximum value, c) linearizing, with the processor, each primary color colorimetrically, d) printing with the printer a second test chart and determining a maximum value of a combined printing of all primary colors colorimetrically, e) defining, with the processor, a resulting color gamut, f) determining, with the processor, an outer envelope of the color gamut with equal spacings; g) interpolating, with the processor, intermediate values of a resulting calibration table; wherein the step c) comprises: linearly scaling tonal values of a primary color so that the maximum value of the step b) corresponds to a tonal value 100%; determining a total length of a graph of each primary color in the CIELAB color space from a tonal value of 0% to the tonal value of 100% at the maximum value determined in the step b); and subsequently newly correlating the tonal values linearly to a proportion of a traveled length on the graph relative to a total length of the graph, beginning at 0% up to the maximum value that has been determined in the step b) and that corresponds to the tonal value of 100%.
