Lou, thanks for taking the time. Wish you all the best for the new year ! Especially no color in your B/W prints. By the way, this profile Europe...FOGRA27.icc came with CS2. It's not the best choice - better is ISOcoated-v2-eci.icc. Your much appreciated explanations are clearly in contradiction to text book knowledge: offset inks are transparent filters with thickness 1 or 2 micro- meters. Therefore a new and fresh interpretation is welcome. There are two open questions: 1) Which black point is used for BPC - the darkest black or the darkest neutral black ? 2) These CLUTs are using n points on each axis C-M-Y-K, n=11 for Europe and n=16 for ISO. All combinations are used, which results in 16^4 = 65536 sets L-a-b. Where is the ink limit ? In the moment I'm programming graphics for gamut boundaries in 3D and 2D, similar to ProfileMakers Gamut View. Best regards --Gernot Hoffmann
