Color correction apparatus

A color correction apparatus for effecting a plurality of kinds of color correction, comprising:

• input means for inputting digital color image data;
• color-correction calculating means for effecting the plurality of kinds of color correction of the digital color image data inputted to said input means, in one stage of synthesized color correction;
• and
• output means for outputting the digital color image data subjected to color correction by said color-correction calculating means;
• wherein said kinds of color correction actually used for a given correction include color correction as standard color transformation, and color correction for correcting a difference in color output density due to at least one of a printer condition, comprising a condition related individually to one or more of different types of printers, a change in the printing environment or a change in printer characteristics over time on an output apparatus side, and a printing condition, comprising a condition related individually to the conditions of printing the image on a printing machine comprising at least one of the type of printing paper and printing environment for outputting a color print image on a color printing machine side, and wherein said standard color transformation comprises corrections independent of said conditions individually related to a printing machine side and an output apparatus side.
