CMYK Printing

CMYK is a color register model used in color printing. It uses the principle of color mixing of the three primary colors of the colorant, plus black ink, and a total of four colors are mixed and superimposed to form the so-called “full-color printing.” The four standard colors are:

C = Cyan  M = Magenta  Y = Yellow  K = Black


Halftone (also called dot) is the use of the size and density of dots per unit area to express the lightness and darkness of the image through the visual effect of juxtaposed mixing. When CMYK is printed, four colors of halftone dots are combined to form a color image.


If the design artwork has more than 3 colors, then 4-color printing may be the most economical. CMYK printing is the most widely used and cost-effective color system in commercial printing.


Since the color is a mixture of dots and other dots, it is likely that the color will vary depending on the printer and job. Qingteng’s color management system can display good color quality on different substrates, and maintain color consistency during different printing processes.

Compared with RGB display

CMYK is used for printed media, while RGB is used for monitors, televisions, projection, and other light-based display technologies. CMYK ink is required for printing. If your artwork is made in RBG, it needs to be converted to CMYK. The conversion is usually done through a color management system.
