What is an input profile / standardization?
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 two 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
toners 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.
