摘要： An alogrithmic method is identified for compensating for thermochromaticity errors in insitu spectral color measurements of a color printing device. A difference is mapped between spectral measurements of a printed color generated by the color printing device measured at a first or hot temperature and at a second or cool ambient temperature where the mapping comprises a referenceable characteristic of the color printing device. The spectrophotometric measurement of a hot color is compared with colors obtained with thermochromaticity compensation matrix to assess if the measured color corresponds to the desired color which will result when cooled to ambient temperature.

摘要： An automatic gray balance control system to produce TRCs for all primary colors in a reproduction device and for each pitch of a photoreceptor system by printing target patches for each pitch, measuring the output colors, and automatically readjusting the tone reproduction curves until a satisfactory level of accuracy is obtained as compared to the theoretical desired output. The system produces pitch-based gray balanced TRCs that are updated frequently for each pitch, with different TRCs for different pitches, to ensure consistency in output from pitch to pitch as well as from page to page on a given pitch.

摘要： A marking device is provided which is capable of operating in a standard output color gamut mode or a non-standard output color gamut mode. The device includes: a color manager that performs color processing on input color data in accordance with a calibration of the device; and, a marking engine that applied colorants to an image-receiving medium in accordance with output from the color manager. Suitably, when the device is operating in the non-standard mode, then the calibration of the device which is conducted is an off-gray balance calibration.

摘要： A printer or other marking engine includes a marking material transfer device, such as a photoreceptor drum or belt, that includes a plurality of pitches. Each pitch receives an individual color of marking material and conveys the marking material to a substrate. The marking engine forms a desired image in a main image area of the substrate using marking material from one or more of the pitches, and produces a target patch pattern for each of the pitches in a margin area located outside the main image area. A measuring device such as a spectrophotometer is used to measure each target patch pattern, and based on the measured values, an individual color calibration is performed for each pitch for use in a subsequent marking operation. The color calibration may include generating or modifying a tone reproduction curve for each pitch based on the measured values. The margin area may be later trimmed off, thereby removing the portion of the substrate on which the target patch pattern is formed.

摘要： Spectrophotometer color measurement with a target illumination system and a reflected illumination sensing system where the target surface is variably spaced from said spectrophotometer. Color correction calibration information corresponding to color measurements for known different spacings of a test target surface from the spectrophotometer are obtained and stored. In use, the spacing of the actual target surface from the spectrophotometer is measured to provide a target spacing information signal. That signal is automatically combined with the stored color correction calibration information for the corresponding distances to provide at least partial correction of color measurement errors of the spectrophotometer for variable spacing of the target surface relative to the spectrophotometer even with low cost fixed focus optics. The spectrophotometer output can be so corrected by changing the target illumination, such as by LED pulse width changes, and/or by corrective adjustment of the measured reflectances.
