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…


Using ColorPort for QTR grayscale and alt-process profiling

ColorPort is free utility from XRite that allows users to make and measure profiling targets with a wide variety of spectrophotometers, including the versatile 1Pro. This software and hardware combination is the modern day equivalent to yesterdays densitometer that provides much more information and functionality. I’ve been using ColorPort on a daily basis since 2005 and love it’s flexibility and versatility. If one is savvy enough to hack color patch spreadsheets and XML files, one can design beautiful targets for nearly any profiling purpose. I’ve preferred ColorPort over MeasureTool for…
