Spot color application in printer device
First Claim
1. A method of matching a printed color to a color sample at a printer device, said printer device comprising a color scanner device, said method comprising:
- offering a color sample to said color scanner device;
generating a color characterization data from said color sample;
generating a plurality of variation color data corresponding to a plurality of variations of said color sample;
printing on a print medium said plurality of variations of said color;
selecting an individual color of said plurality of variations of said color; and
inputting a data describing said selected individual color by scanning said selected individual color with said color scanner device.

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.

16. A method of matching a printed color to a color sample, said method comprising:
-
generating a color characterization data from said color sample, by offering a color sample to scanner device, and generating said color characterization data in said scanner device; generating a plurality of variation color data corresponding to a plurality of variations of said color sample, by printing a plurality of colors in a two dimensional array on a print medium, said plurality of colors corresponding to a plurality of color coordinates around said color characterization signal; printing on a print medium said plurality of variations of said color sample; selecting an individual color of said plurality of variations of said color sample; inputting a data describing a selected said individual variation color, by scanning an array of printed color spots, each said color spot corresponding to color variation in color space around said color characterization data, to obtain a scanned color spot data; and storing said selected individual color as a color book data.

17. A printer device capable of matching a printed color with a color sample, said printer device comprising:
-
an interface capable of inputting color characterization data describing a color of said color sample; a color generation component for generating a plurality of variation colors placed in positions in color space around a position of a color specified by said input color characterization data; a scanner device for scanning at least one color from said color sample, and generate a color sample characterization data corresponding to said color of said color sample; a color book memory for storing data describing a said color; a printer mechanism operable to print a plurality of color spots corresponding to said plurality of generated variation color in a two dimensional format on said print medium; and a scanning algorithm operable to scan a two dimensional array of color spots printed onto a print media by said printer device, to recognise an individual said color spot selected by a user, and to obtain a data describing said selected color spot.
