Working with custom ICC profiles for coloration in coloring systems requires having the same ICC profile installed in the computer where neoCatalog is installed. The profile will be used to generate the previews to get the same color view as in the coloring systems and to be able to use soft proofing. Here you can upload the profile. 

To access the color profiles table, go to 'Management' in administration and find the listed options in 'Materials'.  Here you can upload the profile in neoCatalog. 

The profile will be stored in /neoCatalog/Profiles/.
