Abstract
To translate a physical color to a color space of a printer device, a color patch is scanned using a printer's internal scanner. The printer then automatically prints that scanned color, together with a range of variations of that color, on the print media on which printing is to occur. A user may quickly and easily select a color match from the range of colors printed, by visual inspection. The user enters the selected color into the printer, using for example a number or position code, or by marking the selected color on the print media, which is then re-scanned by the printer. Thus, an iterative prior art manual procedure of color modification using color data determined by spectrophotometers is avoided.
