09851928 · 2017-12-26 · ·

In one embodiment, a processor-readable medium stores code representing instructions that when executed by a processor cause the processor to print a print job, and determine target color data for each sheet of the print job while printing the job. The instructions further cause the processor to continually save the target color data to a server for each sheet of the print job as each sheet is printed.

METHOD OF MAPPING SOURCE COLORS OF AN IMAGE USING A LUT HAVING COLORS OUTSIDE A SOURCE COLOR GAMUT
20170359491 · 2017-12-14 ·

According to this method, the mapping color LUT has input colors that sample not only a source color gamut (included in an input encoding color space in which inputs colors of this LUT are encoded) but also a portion of the input encoding color space which is not included in the source color gamut. Preferably, this color LUT further includes output colors located outside the target color gamut. Accuracy of the mapping is improved, notably for source colors located near the boundary of the source color gamut.

CORRECTING COLOR DIFFERENCES BETWEEN SCANNER MODULES

An example disclosed herein analyzes a first scan of a first target scanned with a first scanner module of a scanner, analyzes second scan of a second target scanned with a second scanner module of the scanner, identifies a color difference greater than a threshold color difference between the first scan and the second scan, and adjusts color settings for the first scanner module to correct the color difference to less than the threshold color difference.

METHOD AND SYSTEM FOR CHECKING COLOR AMONG A PRINTER HAVING AN IN-LINE SENSOR AND PRINTERS WITHOUT AN IN-LINE SENSOR

A method, a system, and a non-transitory computer readable recording medium are disclosed for a first printer connected to a second printer to perform color calibration for the second printer, wherein the second printer does not have a sensor, the first printer including a sensor which measures a media, which has been printed by the second printer and is being fed on a media path of the first printer. The method includes (a) determining the timing to instruct the second printer to print a first measurement chart; (b) instructing, at the timing determined at step (a), the second printer to print the first measurement chart; (c) measuring, by the sensor, the first measurement chart which has been printed by the second printer; and (d) outputting information corresponding to a result measured at step (c).
