A CMYK printer instead uses light-absorbing cyan, magenta, and yellow inks, whose colors are mixed using dithering, halftoning, or some other optical technique. [ 10 ] Similar to electronic displays, the inks used in printing produce color gamuts that are only a subsets of the visible spectrum, and the two color modes have their own specific ...
In printing, under color removal (UCR) is a process of eliminating overlapping yellow, magenta, and cyan that would have added to a dark neutral (black) and leaving the black ink only, called a full black, during the color separation process. Under color removal is used in process color printing.
CcMmYK, sometimes referred to as CMYKLcLm or CMYKcm, is a six-color printing process used in some inkjet printers optimized for photo printing. [1] It complements the more common four-color CMYK process, which uses only cyan, magenta, yellow and black, by adding light cyan and light magenta.
GCMI, a standard for color used in package printing developed by the Glass Packaging Institute (formerly known as the Glass Container Manufacturers Institute, hence the abbreviation). HKS is a color system which contains 120 spot colors and 3,250 tones for coated and uncoated paper. HKS is an abbreviation of three German color manufacturers ...
The ICC profile for a printer is created by comparing a test print result using a photometer with the original reference file. The test chart contains known CMYK colors, whose offsets to their actual L*a*b* colors scanned by the photometer result in an ICC profile. Another possibility to ICC profile a printer is to use a calibrated scanner as ...

This so-called gamut mismatch occurs for example, when we translate from the RGB color space with a wider gamut into the CMYK color space with a narrower gamut range. In this example, the dark highly saturated purplish-blue color of a typical computer monitor's "blue" primary is impossible to print on paper with a typical CMYK printer. The ...
Often a fourth ink, black, is added to improve reproduction of some dark colors. This is called the "CMY" or "CMYK" color space. The cyan ink absorbs red light but transmits green and blue, the magenta ink absorbs green light but transmits red and blue, and the yellow ink absorbs blue light but transmits red and green.
