A color correction method and apparatus using a four-dimensional search table (COLOR CORRECTION WITH A FOUR-DIMENSIONAL LOOK-UP TABLE)

摘要

The present invention generates a search table 42 for the purpose of generating in the second printing system 66 an image having characteristics similar to the color characteristics of the image generated in the first printing system 56, To a method of operating the computer system (50) to convert a first set of digital information defining a corrected color image into a second set of digital information for the second printing system. The look-up table can be used initially to match color measurement data 72 from a particular test target pattern 58, 68 for each printing system, and then experimentally by applying an interpolation technique to evaluate the appropriate conversion for any input Respectively.
