Hi I am looking for the right quads to start with for the PiezoDN with a Pro4 inkset. I see many different folders for the Pro4 and am not sure what is the latest. This is the folder I am using 7900-9900-PiezoDN-ProK4
All PiezoDN curves are Pro4, they do not use the Or or Gr channels.
Download/Install most recent PiezoDN and you should see updated curves. I believe the ProK4 folder is from when these were beta
