I never update the calibration curve. If making just a slight change, I copy the target and edit that and then create a new calibration curve.We usually don't edit an older curve but when I fingerprint a press I will name the curve with the press and date and add C1 at the end, then if I copy I will make that C2. That way if I botch something up, I always have my older one to go back too.John
I do it slightly different from Joe but get the same result. We do not linearize, so my current is just 10=10, 20=20 etc and target is the number i get from Curve 3 when we run a fingerprint.I need to start looking at Colorflow since Harmony is being phased out but I just love how simple it is. In Colorflow 8 they pretty much added the Harmony method but I have not had time to mess with it. Making a massive screwup while fingerprinting a press would be a bad thing!
Colorflow is cool, but is a database hog.We had maybe 2-3 snapshots (current and history) and they would tell is that is too many.
We were using the pro... until they closed the plant in January
