- Thread-topic: Profiling using Status T data
>I have an xrite DTP32 densitometer that produces CMY Status T data. Is it possible to transform this data for use with a profiling package requiring LAB data?>
Sorry, not really practical if not indeed impossible. If one were really ambitious, something similar might be accomplished. It IS theoretically possible to utilize a densitometer for profiling, much like scanner profiling where one scans the target (measures the target with the densitometer) and develops a correlation between the RGB data from the scanner (RGB filter measurements from the densitometer) and the lab values of the target. No profiling packages work with densitometer measurements this wat that I'm aware of, so you'd be on your own to build the look up tables, and you'd still need to get Lab measurements of the target to begin with...like the reference file supplied with the scanner target. Mayby someone out there could comment on whether some formulas for converting XYZ into density could be somehow reversed, but this likely wouldn't be as accurate a way to go anyway. So you really need a spectrophotometer...or a profiling service.
