Process Color
CMYK is also called 4-color Process. Colors in CMYK images are composed of
varying
amounts of Cyan, Magenta, Yellow and Black. This is the way a printing press
prints color,so it is vital that your image be in this color mode. For 1-color Process it needs
to be
grayscale or bitmap (which only use Black).
Spot Color
Refers to a method of specifying and printing colors in which each color is printed with its own ink. In contrast, process color printing uses four inks (cyan, magenta, yellow, and black) to produce all other colors. Spot color printing is effective when the printed matter contains only one to three different colors, but it becomes prohibitively expensive for more colors. Most desktop publishing and graphics applications allow you to specify spot colors for text and other elements. There are a number of color specification systems for specifying spot colors, but Pantone is the most widely used. |
