What is an input profile / standardization?
Definition
An input profile / standardization defines what color space you must use to interpret the color
information of the file you want to print in a correct manner.
The main input profiles (color spaces) are the following.
•
RGB
The RGB color space is based on the RGB color model. RGB (Red, Green, Blue) is a suitable
color model for computer graphics because the human visual system operates in a similar
manner.
The RGB color space is an
additive
color space, where you can mix colors based on light. You
can create white light if you add equal parts of each of the three primary colors: red, green, and
blue. All three colors are required to produce white and the absence of all three produces
black. In additive mixing, the RGB colors are the primary colors and cyan, magenta, and yellow
(CMY) are the secondary colors.
• CMYK (Colors you print)
The CMYK color space is based on the CMYK color model. The CMYK (Cyan, Magenta, Yellow
and Black color space is a
subtractive color space, where you can mix colors based on
subtracting light energy from the spectrum. The CMY inks are used to create RGB colors. All
three inks are required to produce black and the absence of all three produces white. In
subtractive color mixing the CMY colors are the primary colors and RGB are the secondary
colors.
