Create a reference from the values of an imported range

Just as it is possible to validate a proof with a standardized gamut, it is also possible to check prints with gamuts containing many more reference colors.

This method works with both CMYK and RGB tables and is very similar to spot color control.

For more information, see the chapter: Creating a reference from a spot color chart

CMYK tables must contain CMYK and {Lab or xyz or spectral}
values RGB tables must contain RGB and {Lab or xyz or spectral} values

Importing a reference range

In our example, we will use the IDEAlliance GRACol2013 CRPC6 reference file of 1617 colors.
It is also possible to use a PANTONE color chart or a measured RGB chart of the TC9.18 RGB type for example.

On the menu bar, click File> Open File

Select the reference file then click on the " Open "
button Generally, reference organizations such as CIE, Fogra, UGRA or IDEAlliance, to name but a few, provide files in the CGATS standard (.txt or .it8).
But Coraye supports a lot more formats.

Controlling an RGB or CMYK gamut is very similar to that of a Mediawedge, except that there are more measurement lines.
