I'd like to know the basis for the size of the CLUT tables in i1Profiler generated printer profiles.
I use the high quality settings in i1Profiler, and the BtoAx tables are always generated the same. Using ICCProfileInspector (attached image) I can see three inputs, L* - a* - b*, each has 37 entries. I'm assuming L* goes 0 -100, an a* and b* -128 to +128 (127?) with 18 being the 0 point.
In the image I have set all three sliders to 18, should represent L* = 50, a* = 0, b* = 0, the output RGB seems about right. The tag contains 340,00 bytes, which I can rationalize as 37 x 37 x 37 x 2(16bit entries) x 3 channels = 304,000 plus some sort of overhead.
So why 37 for the CLUT dimension? Seems like a strange choice.
