Color image recording device, system, and method

A color recording device that performs printing by inputting RGB image data, the recording device comprising:

• print characteristic data recording means for recording print characteristic data of the color image recording device;
• color region selection means for selecting a color region;
• weighting means for weighting the print characteristic data according to the selected color region;
• and
• matrix coefficient computation means for computing a matrix for converting the print characteristic data into data unique to the color image recording device using a setting value established by the color region selection means and the print characteristic data recording means,
• wherein, the matrix coefficient computation means converts the data using each weighted data item from the print characteristic data recording means.

A method for forming color data, on the basis of RGB signals, for printing with a color image recording device, the method comprising:

• recording printing characteristics of a printing device with a printing characteristic data recording means;
• selecting a color region with a uniform color space;
• determining a color adjustment for the selected color region with a color adjustment setting means;
