What is an input profile / standardization?DefinitionAn input profile / standardization defines what color space you must use to interpret the colorinformation of the file you want to print in a correct manner.The main input profiles (color spaces) are the following.• RGBThe RGB color space is based on the RGB color model. RGB (Red, Green, Blue) is a suitablecolor model for computer graphics because the human visual system operates in a similarmanner.The RGB color space is an additive color space, where you can mix colors based on light. Youcan create white light if you add equal parts of each of the three primary colors: red, green, andblue. All three colors are required to produce white and the absence of all three producesblack. 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, Yellowand Black color space is a subtractive color space, where you can mix colors based onsubtracting light energy from the spectrum. The CMY toners are used to create RGB colors. Allthree inks are required to produce black and the absence of all three produces white. Insubtractive color mixing the CMY colors are the primary colors and RGB are the secondarycolors.What is an input profile / standardization?Chapter 3 - Define your Workflow with Océ Express WebTools 171
