So my question about logo2cgats is this : suppose I use IT8.7/3 Basic (only 182 patches), when importing the measurement file into argyll's ti3 format, will I still be able to create an ICC profile through "profile"? Or is there a minimum? I remember once creating an ICC profile with argyll based on as little as 60 patches.
There's no minimum really except for practicality, ie. probably 4 (enough to occupy 3 dimensions). You won't get very far without white either I expect. At one stage I experimented with creating a profile from the colors in a Fogra strip (46) patches, using an indirect method - create a model profile using mpprof from the .ti3, and then use it to create a larger number of dummy samples using fakeread (say 1000), before creating an ICC profile. With some devices this worked quite well, with others not so well. Graeme Gill.
