Color spaces
Devices as monitors and printers create colors in a different way. Because of these differences
colors are described differently for each device.
The different methods of describing colors are called color spaces. The color space specifies how
color information is represented in an image. Each device has its own individual color space and
range of colors that it can display or print. In addition, each device can have one or more ICC
(International Color Consortium) profiles. ICC profiles are used when an image or a object is
converted to the color space of a different device.

RGB
Devices such as monitors, digital cameras, and scanners generally use RGB color spaces to
describe colors. Two implementations of RGB color spaces are sRGB and Adobe RGB.
CMYK
Color printers use the CMYK color space. Implementations of the CMYK color space vary from
printer to printer and from medium to medium. FOGRA has several implementations of the
CMYK color spaces.
Input profiles and output profiles
An input ICC profile can translate color data created on one device (such as a monitor) into the
Profile Connection Space (PCS). The Profile Connection Space (PCS) is necessary to connect the
input and output color space by describing the colors in a device-independent way. The Profile
Connection Space (PCS) color space, such as the CIELAB color space, defines colors as true
representations of what the human eye can perceive.
There are input profiles to translate RGB color data and input profiles to translate CMYK color
data.
The output ICC profile translates the color information from the Profile Connection Space (PCS) to
the CMYK color space of the printer.
