Curves cannot be installed into QTR

Piezography Professional Tools
1

After creating a new profile curve in PPE, I copy it to a Sublime text document and save it to my curves folder. The command to Install the curves no longer works. My mac just updated to Ventura 13.2 and this is when the problem started. I have the latest versions of Print Tool, QTR and Sublime text on my Mac.

Any ideas how to install the new curves? I did try to just copy the new curve into the QTR folder in the library, but Print Tool does not see it using this method.

Many thanks
David

If you search around for this issue you can find a response from Walker. The fix is to run a Terminal command:
sudo chmod -R 777 /Library/Printers/QTR/quadtone

Afterward you’ll have to enter a password for the computer user.

Occasionally I have to run the command when installing new .quad files and I assume it happens after installing a MacOS update that resets permissions.

Thanks - problem solved!
Super helpful - really appreciate you taking the time.

Hello!
I have the same problem.
I have been trying to get to the bottom of the problem for days.
I am not a programming expert and not able to install the curves without help.
Thanks a lot, Heidi

If you download and install the most recent community edition of piezography it will fix it

Thanks for help, Walker.
I am quite at a loss. S

So sorry, I did not realize this was PiezoDN. I need to convert to most recent version of QTR which support the violet channel.

This will take a bit.

Actually I realize that this curve was only given to Taos.

Here it is, this should work:

P900-Pro-PiezoDN-Master.quad (9.1 KB)

Walker, your are right, the new curve works. That makes the work easier, so many thanks for your time and knowledge! Now I do a pt pd print test, and also try to adjust a new curve. I will then give a short feedback - whether everything has proven itself in practice. You made my day! Ciao Heidi

Please note that this curve is for print-out palladium so it will be a dense neg most likely. It will need some tuning and calibration for develop-out PtPd.
