ChromaMax Part 4: Printer Profiling

The final RIP calibration step is profiling. If the base calibration steps performed beforehand aren’t done properly, you won’t get a get profile. But even if the previous steps are performed perfectly, there’s a surprising amount of profiling variables that are important to discuss to ensure we get the best ICC profile possible. ChromaMax targets use ‘bottom weighted’ patches that allow us to characterize deep shadow color better than traditional targets that distribute patches evenly throughout the tonal range. In the same fashion, its important that we create profiling targets that are…


ChromaMax Part 3: Printer Total Ink Limiting

The third RIP calibration step is to set the total, combined ink limit of all the channels together. Any given media might be able to hold 100% of any individual ink, but holding 100% of all 4 or more inks simultaneously without bleeding is another matter. With high quality media, there’s also a certain point at which it achieves maximum Dmax. If we use with a higher ink limit than this we’re just wasting ink without benefit. The Chromamax total ink limit step helps us find this precise sweet spot where we’re achieving maximum print quality with the lowest ink consumption.…
