piezo - p800 - print quality

[VT_Snapper]

Hello all,

Having an issue with print quality on my p800. Running piezo pro and getting weird wash out in 3/4 tones. Ran tests on Hahnemuhle and Moab using piezo P800-Hahn-PhotoRag-Neutral & P800-Moab-Entrada-Neutral curves respectively.

Carts are full and nozzle checks are clear. Any thoughts on fixes appreciated.
