More PRISMAsync colour information
The colour management of PRISMAsync controls the reproduction of colours and handles the
conversion of input colours (RGB, CMYK, spot colours) to printed colours on paper. PRISMAsync
has two instruments for easy colour management across the entire workflow, colour presets and
media families, so that the operator does not need to perform colour management tasks on a job-
by-job basis.
Colour experts can use more colour management functions with the Advanced colour
management license.
See
Colour reproduction for your output
on page 41 for a description on colour presets, media
families and the features of the advanced colour management license.
Below you find more PRISMAsync colour information.
Input and output profiles
Input and output profiles define the transition from input colours, for example the RGB colour
values of a photo, towards output colours, for example the CMYK colour values of your printer.
The colour management of PRISMAsync transforms the colour input space to the colour output
space via the standards of the ICC, the International Color Consortium.
PRISMAsync comes with high quality colour output profiles for both coated and uncoated media.
PRISMAsync links output profiles to media via media families. Each media family has three
different output profiles, for the halftone screens Normal, Fine and Error-diffusion.
Rendering intents
A colour gamut is a set of colours a system can produce. Input colours not always fit in the colour
gamut of an output device. For colours that exceed the gamut of an output device, colour space
rendering intents are used for gamut mapping. The rendering intent tells the colour management
system how to handle colours that do not fit into the destination colour gamut. The following
rendering intents are available on PRISMAsync:
•
Relative colorimetric
Frequently used and suitable for proofing applications on reference paper. White point
compensation is applied. The white point of the output colour space is the colour of the used
media.
•
Absolute colorimetric
Mainly suitable for proofing applications on bright white paper. No black and white point
compensation is applied, so the precise input paper colour is simulated on the used media.
•
Perceptual
Mainly suitable for photographic input. The colours are mapped in a continuous way and
colour nuances are respected. White and black point compensation is applied.
•
Saturation
Mainly suitable to obtain highly saturated colours and business graphics. Out-of-gamut colours
are mapped to more saturated colours. White and black point compensation is applied.
Spot colours
Spot colours standardise and predict colours, so that output colours always match a specific
colour value. Spot colours allow to print unique brand colours for logos or business graphics.
Spot colours are converted to the proper CMYK output colour value via spot colour tables or spot
colour libraries.
You find the spot colour definitions in the Settings Editor. To select the most appropriate colour,
a patch chart print is available. Use this print as a spot colour representation on the media you
