2-2 Simple and Advanced Workflows

RGB, CMYK, and PANTONE colors

Colors can be defined in several different color models, the most common being RGB,
CMYK, and the PANTONE color matching system. Each model requires a different
color conversion at the ColorPASS. These different color conversion workflows are
explained below.
• RGB source profiles and color rendering dictionaries are used to map RGB colors
through a device-independent color space to a destination space, either the full
copier gamut in a short-run printing workflow or CMYK simulation in a color
proofing workflow.
• CMYK colors are device-dependent. In a proofing scenario, colors specified in
prepress applications are adjusted so the gamut of the ColorPASS copier can
simulate that of the press. In a short-run printing workflow, specifying CMYK
colors according to the calibrated copier output eliminates the need for simulation
during printing.
• PANTONE spot colors are special inks manufactured to run on an offset printing
press. Spot colors can be simulated using CMYK copier toners or process color inks.
Two basic workflows exist for printing PANTONE colors to the ColorPASS:
Spot Color Matching On instructs the ColorPASS to match the output of the copier
to the PANTONE spot color.
Spot Color Matching Off instructs the ColorPASS to match the copier output to a
Pantone-specified process simulation. This CMYK combination is then printed with
the CMYK Simulation setting you choose, such as SWOP or DIC, and CMYK
Simulation Method set to Full.
