Odd Images from Piezography after Ventura Upgrade (MAC)

InkjetMall Customer Support General Discussion & Misc Support Questions

After upgrading my MAC to Ventura, Piezography prints have been unlike anything I printed before the change. The tones of the prints are far from the previous tones. In particular some of the gray areas appear as a “plated,” sometimes textureless field in the image. Any recommendations to fix this would b very welcome.

I used this image for a test:

Set the file into Print Tool:

Print Tool 1
Print Tool 1962×541 78.3 KB

QuadP600-Pro is selected:
Print Tool Settings 1

Print Tool is set to manage colors, using Piezography Gloss Print.icc:
Print Tool Settings 2

In QTR, curves selected are (1) P600-Canson-Platine-Cool and (2) P600-Canson-Platine-Neutral:

Results (captured by iPhone) are unsatisfactory, with weird areas of gray in branches above wall on left and in wall on right:

It looks to me like you are missing Warm dark grey and/or the HD PK ink entirely. Do a nozzle check and cleaning if need be. (note that the gloss channel will show as a blank, so you should have only one blank channel in the nozzle check).

Then print with this workflow but also make sure Black Point Compensation is turned on.

That should do it.

Do regularly nozzle checks. Never run a printer with blocked nozzles.

Ok. Will do. And I will report back.

This problem continues, and in both my P600 and P800.

Nozzle test for P600:

Nozzle test for P800:

And yet the bizarre tonality continues. Reprint using QuadP600-Pro (black point compensation selected in Print Tool):

Any further advice will be welcome.

It might be worth downloading and installing the most recent version of QTR. I know Roy updated this last week due to inking issues that were present . . .

Thank you, Walker!

I downloaded and installed QTR 2.8.2, reinstalled the associated PZ curves. Now both QuadP600-Pro and QuadP800-Pro are printing as they should. Problem solved.
