Color Correction

are interpolated and then displayed approximately. The more colors are measured, the

more precise the color representation will be later. Since the image of the monitor

changes with time, this calibration should be repeated from time to time.

A calibrated screen ensures that a certain hue is displayed

realistically on the monitor, but that does unfortunately

not mean that the display also corresponds to the later

print result.

Since the CMYK color space is smaller than the RGB color

space, it is strongly recommended to display the image

on the monitor with activated CMYK color proof function

before printing, so that the target color space can be

rated most bindingly.

To create an ICC profile it is required to print a certain color palette on a specific

substrate and then to read it in with a colorimeter. Thru that measuring, the color

calibration software can determine the extent to which which hue differs from the

desired hue.

However, the accuracy of the measurement and the resulting ICC profile depends on

many other factors, such as the print quality, the background, the number of color

patches used, the quality of the measuring system, the setting of many parameters and

much more.

The documentation of the software "ArgyllCMS" at

http://www.argyllcms.com/doc/ArgyllDoc.html provides a deep technical insight into the

many possibilities and the influence of color correction on printing results.
