摘要： Methods and systems herein provide for calibrating for a plurality of different paper types. In one embodiment, a system for calibrating a printer includes a measurement module operable to detect colors printed on a first tangible medium by the printer and convert the detected colors to a detected color characterization. The system also includes a storage module operable to store a calibration file. The calibration file includes color characterizations of a plurality of different tangible mediums and each color characterization includes color measurements for one of the plurality of different tangible mediums obtained from the printer via the measurement module when the printer is calibrated. The system also includes a calibration module operable to compare the detected color characterization to at least two color characterizations of the calibration file and determine an adjustment to an output color scheme of the printer based on the comparison to calibrate the printer.

摘要： Systems and methods for color conversion from one CMYK color space to another CMYK color space. The system receives a color defined by a first coordinate in the first CMYK color space. The system converts the color to a second coordinate for the second CMYK color space, and determines a location in a perceptual color space for each of the first coordinate and the second coordinate. The system further identifies a distance between the locations in the perceptual color space, and reduces the distance in the perceptual color space between the two locations by iteratively revising the second coordinate in the second CMYK color space while holding the black level of the second coordinate constant.
