About this Tutorial

This tutorial provides a practical introduction to multicolor profiling with Equinox characterization data.

Equinox is a color technology by Esko for expanded gamut printing with a fixed set of inks. Multicolor printing processes can thus be characterized with a combination of multiple standard 4c test charts (e.g. ECI2002).

Usually, one of the characterizations describes the CMYK color space. The other characterizations describe color subspaces consisting of process colors combined with one spot color (e.g. CMYK, OMYK, CGYK, CMBK).

Accordingly, each 4c Equinox color space needs a corresponding characterization in GMG OpenColor. The characterizations are combined in a project and can then easily be used for creating multicolor profiles.

	What to do	Short description	See also
1	Add characterizations	For each color subspace (e.g. CMYK, OMYK, CGYK, CMBK), add one characterization and import the corresponding measurement data. To ensure that the Printing Process and Media settings match, duplicate the first characterization and then edit it.	Add Characterizations
2	Combine characterizations	Create a GMG OpenColor project for the printing process you want to proof, using the same Printing Process and Media Settings you defined for the characterizations in the previous step. Link all added characterizations to this project.	Combine Characterizations
3	Set the ink sequence	Set the ink sequence of the project to the ink sequence of the actual printing process.	Set the Ink Sequence
4	Rank characterizations	As some ink combinations show up in more than one set of characterization data, you need to define the order of sequence in which GMG OpenColor will search for a specific ink combination. GMG OpenColor will use only the first found ink combination and ignore further lower ranking matches.	Rank Characterizations
