CMYK is a popular term that you usually find in a commercial print service but what CMYK stands for? It seems like a crucial part of printing so it will be beneficial if you know about it and why it becomes a part of the printing color process.
What is the Definition of CMYK?
CMYK stands for Cyan, Magenta, Yellow, and Key which is popular as an acronym. Those letters refer to a group of colors used in the printing process. A printing press applies ink dots to create an image using those four colors.
A printing press also makes up the images by combining CMYK colors to different degrees using physical ink, a process called subtractive mixing. Initially, all colors come in blank white. Then, the ink layer reduces the original brightness to present the required color.
The combination of all colors results in pure black color. People usually use CMYK when they do project designs and transform them into physical printouts and not for screens. That is why you often see the CMYK option in the printer settings because it helps you to create printouts as intended.
What is the Meaning of Key in CMYK?
Aside from what CMYK means, some people are curious about the meaning of ‘Key’ in the acronym. ‘Key’ is a black color that becomes the primary color to determine the image result. It uses K instead of B to avoid people misunderstanding it as blue color.
‘Key’ may also be the black plate on the printing process that aligns with the other three colors to create a perfect match for the final image. By looking at the possibility, K can be any color plate as long as the black is unusable.
Black ink offers depth and shading while other colors provide different accents depending on how you combine them with the other. For instance, combining yellow and cyan creates a green color.
Some also address ‘Key’ as an ancient press in 1843 that featured screw keys to identify how much ink needed to create a preferred result.
Why Do Printers Apply CMYK?
CMYK stands for four colors that are easier to standardize because of the color spectrum owned. Hence, CMYK is more famous in commercial printers than RGB. Commercial printing using these colors creates perfectly consistent print products as long as the printer works.
Meanwhile, RGB offers many variations but does not guarantee the color’s consistency throughout its performance. You can monitor CMYK with a GMG scanner and other compatible software. It enables the printing press to create a standard color regardless of the machine’s characteristics.
It is why commercial printers use CMYK more often. It ensures color consistency across point runs and through different printing machines. Moreover, it provides better looks on paper.
Those pigmented colors over the white canvas create a darker look. It is one of the functions of CMYK as subtractive in the printing tasks.
Knowing what CMYK stands for and how it affects the pigment allows better control when creating the final color and image. The more you focus on this color mode, the easier for you to forecast how the file will transform into final printouts.
