Method and system for providing closed loop color control between a scanned color image and the output of a color printer

摘要: A method and system for continuously correcting errors in color output of a copier or printer caused by events that occur between the input image scanner driven thereby. This includes, among other things, continuous comparison test pattern data, TP , from small gamut "patch" having only selected few number pixels therein with out to generate correction conversion factor, H. Then, H is used update an initial full scale look up table which was initially prepared gamut. The has F old convert new where =H·F . In this manner, corrects undesirable changes parameters table, such as quality print media, ink, dye loading, ink drop volume, pen types calibration devices.
