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

I don't know whether this is relevant, but Xrite's ColorPort and Babelcolor's Patchtool are two GUI programs which many color consultants used for years to create targets. I think both are free or abandonware these days. Patchtool in particular could read color out of targets, rearrange the squares etc.

ColorPort looks simple at first glance, but it can be reconfigured, and Bill Atkinson used it to generate monster target strips

AFAIK the Cgats formats etc are cast in stone, and therefore any old flexible program remains pretty useful these days, no need to reinvent the wheel or the bottle.
