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.

摘要： In summary, the present invention provides a method, apparatus and program product for calculating an estimate of the amount of toner coverage required for printing print data defined in a compressed data stream. The estimate is obtained with reduced processing by obtaining coverage data from a partially decompressed formed of the data stream and using this to obtain the coverage estimate, thus removing the need to do a full de-compression of the data stream. For example the coverage data is a count of toned pixels for at least one intensity level.

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： Disclosed is a method, system, and program for reducing toner in an image comprised of raster pel data. A determination is made of pels surrounding subject pels. For each subject pel, a sub-pulse width power is generated to charge a sub-pel region within the subject pel based on a pattern of the surrounding pels of the subject pel. Further, for each subject pel, position information is generated indicating an alignment of the sub-pel region in the pel. The position information is used to position the sub-pel region produced by the sub-pulse width power in the pel.

摘要： Control system which measures overshoot or undershoot time of a controlled variable with respect to a set value and adjusts a proportional count if the overshoot or undershoot time period exceeds fixed values. The proportional count is used to control the system output in a proportional manner, such as supplying k out of every n cycles of power, where k represents the proportional count. To prevent excessively long periods of overshoot or undershoot, an overlimit detector provides adjustments of the proportional count when the overshoot or undershoot measured time exceeds an overlimit value.The control system has general applicability but is described in the temperature control of a fuser hot roll such as used in electrophotostatic copiers.
摘要翻译：控制系统相对于设定值测量受控变量的过冲或下冲时间，并且如果过冲或下冲时间段超过固定值，则调整比例计数。比例计数用于以比例方式控制系统输出，例如在每n个功率周期中提供k，其中k表示比例计数。为了防止过长时间的过冲或下冲，当过冲或下冲测量时间超过上限值时，叠加检测器提供比例计数的调整。控制系统具有一般适用性，但是在诸如用于静电复印机中的定影热辊的温度控制中进行了描述。
