Chapter 1. Color Management Background Color Management ICC Profiles Captures a devices color characteristics • All the colors the device can display, output or measure, including white point • Provides a conversion between a device Dependent (RGB & CMYK) and a device Independent color space (Lab) CMYK L*a*b* or RGB L*a*b* • Created by a software utility (MonacoProfiler) and a set of patches • ALL ICC PROFILES ARE PAPER, INK AND DEVICE SPECIFIC ICC Profile Creation 1. Create a patch chart (908) with Monaco and print on the press with the appropriate linearization applied* 2. Use Monaco to scan the patches with a spectrophotometer 3. Monaco knows the CMYK recipes that it put into the patch pattern, so now it can build a database of what CMYK produces what Lab & vise versa. C M Y K = L a b 0 41 97 0 = 71 -9 -27 56 15 0 0 = 75 17 78 27 0 85 0 = 83 -24 66 0 97 73 13 = 38 59 23 4. From these few patches, the profile will build a database of all the possible CMYK recipes and their Lab equivalent 5. Works exactly the same for RGB 1 - 12 CS600 System Controller
Chapter 1. Color Management Background Color Management ICC Profile Creation & Linearization The * on the previous slide indicated that the ICC patch pattern be printed with the appropriate linearization level. • This is for the same reasons we apply linearization to real data • Prevent paper/ink interaction problems • Achieve linear tone • Since we do this manipulation outside the profiling software (Monaco), we must ALWAYS do the manipulation (linearization) whenever we use the ICC profile Monaco creates. • To make sure we always do this, EFI requires that we embed the linearization curves in the ICC profile • The Color Toolkit does this embedding More of the system Source ICC Profile (RGB) L*a*b* COLOR MANAGMENT MODULE L*a*b* Destination / Output ICC Profile (CMYK) How does this system know if it found the closest Lab match in the output profile? And what do we do if there is no match? Color Management and Workflow User Guide 1 - 13
