In the chapter “Linearizing Piezography” of the Piezography Manual, the requirements say
- You must have a spectrophotometer (i1Pro, i1Pro2, DTP70, ColorMunki, Spyder, etc).
- You must be capable of using said spectro and the software that runs it (ColorPort,
i1Profiler, ColorPicker, SpyderPrint, etc).
Although I do not plan to purchase a spectrophotometer right away, it would be helpful for planning and budgeting purposes to know which of the above-mentioned devices meet the minimum requirements for linearizing a .quad. I would not want to spend the extra money on a device that can do more than measure printed targets. I already have an X-Rite EyeOne for calibrating and profiling my monitor.
