Everyone who is preparing images for different substrates and print processes, knows the problem: color conversion with ICC profiles doesn´t always lead to the desired results. Which means time-consuming retouching work. The bigger the differences in paper tint and color space, the higher the technology target for converting images without changing the color appearance (gamut mapping). This is where the MX technology of GMG scores huge advantages compared to ICC technology. MX profiles can be calculated and optimized in one go, e.g. when calculated for a conversion from ISO Coated v2 to PSO Uncoated v3. Differences in paper tint and color gamut are adjusted in the best possible way.
See for yourself
In the following example, images for a double-page ad (running from the inside of a cover to an uncoated content page of a magazine) are converted from ISO Coated v2 to PSO Uncoated v3.
Hover your mouse over the images and see for yourself.
Reference Image (ISOcoatedv2)
Converted to PSOuncoatedv3 with ICC
Used Profile Settings: SOcoated_v2_v2_eci.icc/PSOuncoated_v3_FOGRA52.icc (Relative + BPC)
Converted to PSOuncoatedv3 with MX
Used Profile for Conversion: CS_con_ISOcoatedv3-52_V1.mx4x
What are the benefits?
By applying GMG MX profiles, many benefits can be gained: conversions from RGB to CMYK are less “lossy”, the image quality is significantly better in difficult areas such as skin tones, gray balance and shadow areas, and all content can be produced to the exactly same color space. GMG color management makes sure the visual impression of an image stays the same after a conversion to another color space, even if the target color space is smaller in size or has a yellowish or bluish paper tint.
