Learn about input and output profiles
You can apply device simulation with or without a DeviceLink profile. A DeviceLink profile
represents the printer you want to simulate. The DeviceLink profile functions as the input profile,
the output profile and one or more rendering intents.
Separation
The process where the output profile converts the colors from the Profile Connection Space (PCS)
color space into the CMYK color space is called separation. The result of the separation is the
creation of the CMYK separation planes.

The outcome of the separation is important for the quality of the printed image, since one target
color in the device-independent color space can be reproduced by different ink combinations on
the printer. To calculate the CMYK values, the output profile takes into account which limits are
set for the media. For example, the total ink coverage limit and the maximum drop size of the
inks. Moreover, the output profile knows where CMY inks must be replaced by K ink and how
much ink must be used for the darkest black.
A CMYK color value is often expressed as four percentages. Each C, M, Y, and K color channel
has the potential of printing at 100%.
