How many color patches are needed for a (good) profile ?

[knowing]

Just an update,
I have updated the release in the link with many printtarg targets based on .ti1 files made for SpyderPrint and LaserSoft Advanced Targets.

Cheers,
K

Yet another update to the example targets. I added many Letter format targets, for those of you that want that.
Cheers,
Knut
