摘要： A color value of output color reproduced based on an output signal value corresponding to an input color value of a grid point in an input color space, which is obtained by sampling a range of the output signal value, are estimated. An evaluation value that evaluates tonality between a color value estimated in correspondence with an input color value of a grid point of interest in the input color space and color values estimated in correspondence with input color values of grid points adjacent to the grid point of interest is calculated. When the input color value of the grid point of interest, whose evaluation value is less than a predetermined threshold value, is obtained, an output signal value corresponding to that input signal value is set in the grid point of interest.

摘要： A method of providing calibration data for a printer includes printing a calibration target using the printer. The target includes a plurality of patch sets, each including a plurality of test patches, each patch having a respective color. Scanned patch data for one of the sets are received from a spot scanner. The scanned patch data values are compared to respective aims to determine a reproduction error value for the scanned patch set. A processor automatically determines which of the sets should be scanned next using the calculated reproduction error value. The process is repeated until all sets have been scanned, or until the reproduction error value is less than or equal to a selected threshold. Calibration data are automatically generated using the scanned patch data.

摘要： Methods of performing print engine calibration create a color space conversion equation for a scanner of a class of printing devices, print test patches on a sheet, and scan the test patches using a scanner of the printing device to produce a scanned RGB value for each test patch. Such methods convert each scanned RGB value to an XYZ pseudo space using the color space conversion equation to produce XYZ values. These methods compare the XYZ values to second XYZ values of white paper to generate DeltaE curves for each of the test patches relative to white paper. The DeltaE curves are interpolated to form an equivalent aim curve. After the equivalent aim curve is determined, the methods periodically calibrate the same or an additional printing device that is within the class of printing devices using the color space conversion equation to produce second XYZ values.
