[234] Spot colour definitions
Spot colours realise a consistent colour and are often used in logos and house style colours.
PRISMAsync Print Server provides a spot colour editor and a set of pre-defined spot colour
libraries, such as PANTONE libraries and HKS libraries. The library of custom spot colours
contains spot colours that users have created in the Settings Editor or on the control panel.

If a source document contains a spot colour definition, the printer needs to know how to print
that particular colour. A spot colour is the combination of a spot colour name, the colour value
and a tint value. The device-independent spot colour definition uses a CIELAB value (Lab value).
When you create a spot colour for a specific media family you use a CMYK value.
You can add more CMYK colour values to a spot colour definition, for other media families that
print the spot colour.
When you want to add a spot colour that has the exact colour value of a sample, for example in
an offset print, you measure the spot colour with the i1 spectrophotometer. (

When you add or edit a spot colour definition, you can print a patch chart to check how the set
CMYK values and small variations on these values appear on media. The printed colours and the
CMYK values of the patches give the best visual match to fine-tune the spot colour for the given
media family.
In the Settings Editor you can import and export spot colour libraries. (

Spot colours definitions can be part of colour mappings. Colour mapping allows you to simply
add spot colour definitions to your jobs. (
