Thanks Roger.
I'm profiling an Epson inkjet (the 2200), and my understanding is that
this printer is highly non-linear. (certainly looks like it to me, anyway)
Started on 836 patches, but saw a definite improvement when I
went up to 3000.
Greg.

I did suprisingly good profiles with only 60 patches last spring, using a
Xerox Phaser 860. Of course more patches was better. But in general, I guess
it¹s a function of the ³linearity² and monotonic behavior of the device that
should determine the sample size.
