Cmyk Ink Simulation - Oki C5400n User Manual

The rendering intents that the printer driver provides are listed below:
> Perceptual
Best choice for printing photographs. Compresses the source
gamut into the printer's gamut whilst maintaining the overall
appearance of an image. This may change the overall
appearance of an image as all the colours are shifted together.
> Saturation
Best choice for printing bright and saturated colours, but less
accurately matched. This makes it the recommended choice for
graphs, charts, diagrams etc. Maps fully saturated colours in
the source gamut to fully saturated colours in the printer's
gamut.
> Absolute Colourimetric
Best for printing solid colours and tints, such as Company
logos etc. Matches colours common to both devices exactly,
and clips the out of gamut colours to their nearest printed
equivalent. Tries to print white as it appears on screen. The
white of a monitor is often very different from paper white, so
this may result in colour casts, especially in the lighter areas of
an image.
> Relative Colourimetric
Good for proofing CMYK colour images on a desktop printer.
Much like Absolute Colourimetric, except that it scales the
source white to the (usually) paper white. Unlike Absolute
Colourimetric, this attempts to take the paper white into
account.

CMYK INK SIMULATION

Affects CMYK data only.
This option simulates what the output will look like on a printing press
using the ink types SWOP, Euroscale or Toyo. If using CMYK Ink
Simulation, it is recommended that you switch off all other Printer
Colour Matching. Select the No Colour Matching option under the
Colour Match option in the printer driver.
