ChromaMax Part 2: Printer Linearization

The second RIP calibration step is to linearize the ink channels with their newly restricted ink limits. This generates a set of curves that should produce a tonal response that is rich in shadow color and neutralizes the combined gray axis. The problem here is that many RIPs are still using curve generation algorithms that were created a long time ago and haven’t been updated. These RIPs rely on the final profiling process to “fix” an imperfect linearization, and the results are “good enough” for many. The G7 process introduced an excellent way of automating the curve generation process for…
