Auto
The best default select as this selects the optimal settings for a general office environment.
Perceptual

Saturation
Best choice for printing bright and saturated colors if you don't necessarily care how accurate the colors are. This makes it the recommended choice for graphs, charts, diagrams, etc. Maps fully saturated colors in the source gamut to fully saturated colors in the printer's gamut.
Relative Colorimetric

Absolute Colorimetric
Best for printing solid colors and tints, such as company logos etc. Matches colors common to both devices exactly, and clips the out of gamut colors to their nearest printed equivalent. Tries to print white as it appears on screen. The white of a monitor is often very
