What is cool black?

In a RGB color space, hex #002e63 (also known as Cool black) is composed of 0% red, 18% green and 38.8% blue. Whereas in a CMYK color space, it is composed of 100% cyan, 53.5% magenta, 0% yellow and 61.2% black. It has a hue angle of 212.1 degrees, a saturation of 100% and a lightness of 19.4%.

Similarly one may ask, what is rich black in CMYK values?

Most print houses utilize a formula C=60 M=40 Y=40 K=100 (240% ink Coverage) or C=40 M=30 Y=30 K=100 (a bit less than average). These formulas are best for rich black. Remember that the term RGB is not utilized in Litho Printing. Therefore you cannot use CMYK formulation on an RGB mode.

Why is Black referred to as K?

CMYK stands for cyan, magenta, yellow, and key or black. These are the four colors of ink used in the traditional method of printing hardcopies of images, called offset printing. The black is referred to as K denoting key, a shorthand for the printing term key plate.

What is four color black?

CMYK refers to the four inks used in some color printing: cyan, magenta, yellow, and key (black). The reason for black ink being referred to as key is because in four-color printing, cyan, magenta, and yellow printing plates are carefully keyed, or aligned, with the key of the black key plate.
