Another PiezoDN Linearization Question

[rcscheibe]

The outcome of my first linearization attempt is a CGATS-out file that states “Invalid linearize curve – not constantly increasing”. Since there is a coherent out file I assume (always scary) that I did the process correctly. So the questions are:

1. What does this error mean and how do I correct it, and

2. Is there a list of the errors that come from the QTR linearization tool?

Attached is the CGATS-out file. Any and all help will be greatly appreciated.

I am operating on an iMac 10.13.2, used a ColorMunki to read the print, and TextEdit, and Numbers to manipulate the numeric outcome.

Looking at your data it looks like you need to smooth it with the cgats smoother tool as described in the manual for PiezoDN. I assume this is PiezoDN calibration as you are posting in the PiezoDN forum. If this is a Piezography Professional Edition question, the smoother you need to use is the Error Corrector google sheet that was sent to you.

Thanks for the quick reply. Yes, it is a PiezoDN linearization. My bad. I was using the wrong set of numbers from the smoother tool. Thanks for the help.
