The CMYK color model (also known as process color, or four color) is a subtractive color model, based on the CMY color model, used in color printing, and is also used to describe the printing process itself. The abbreviation CMYK refers to the four ink plates used: cyan, magenta, yellow, and key (most often black).
The most noticeable result of using light cyan and light magenta inks is the removal of a distinct and harsh halftone or dither dot appearance that appears in prints that use light shades of cyan or magenta on the pure CMYK ink configuration. Usually when printing a dark color the printer will saturate the area with colored ink dots, but will ...
The CMYK coordinates describe the amounts of each of cyan, magenta, yellow and key pigments (such as inks) which are mixed subtractively in order to create a particular color. In Wikipedia, the coordinates are presented as four numbers separated by commas, as in this example for the color orange:
The widespread offset-printing process is composed of the four spot colors cyan, magenta, yellow, and key commonly referred to as CMYK. More advanced processes involve the use of six spot colors (hexachromatic process), which add orange and green to the process (termed CMYKOG).
This printing technique is referred to as CMYK (the "K" stands for key, a traditional word for the black printing plate). Today's digital printing methods do not have the restriction of a single color space that traditional CMYK processes do. Many presses can print from files that were ripped with images using either RGB or CMYK modes.
A 32-bit CMYK image (the industry standard as of 2005) is made of four 8-bit channels, one for cyan, one for magenta, one for yellow, and one for key color (typically is black). 64-bit storage for CMYK images (16-bit per channel) is not common, since CMYK is usually device-dependent, whereas RGB is the generic standard for device-independent ...
The 10,000 steps per day rule isn’t based in science. Here’s what experts have to say about how much you should actually walk per day for maximum benefits.
t CMYK ∈ [0,1] 4 is the CMYK quadruple, t CMY ∈ [0,1] ... since the key plate is black in CMYK printing, it works just as well either way. I do not know which ...
