3d view of profile

Why does the color separation setup in a profile determine how the gamut volume looks in a 3d viewer, such as ProfileMaker? I thought the 3d view was the outer edges of all the possible colors of the device.

Ah - Hah!
The answer is… because not all 3D gamut viewers are created equal!

ProfileMaker shows you the rendered printer direction of the profile, and the ColorThink products show you the “proofing” direction of the profile. So ColorThink shows you the maximum gamut of the printer by default. … yths_26-28
