lost Piezo Pro curves


I have multiple printers with Piezo inks and started using a new Canson edition etching paper with my 7600 SPED inks. I didn’t have a curve for this and saw that this paper was supported on the recent website. I downloaded the new curves and installed them as usual, and have lost all of the curves for QTR specific for the inks. I have 7900 WN, 7600 SPED, and 3800 Piezo DN. How can I get these back?


The old curves (really the last 10 years of published curves) should still be in >Applications>Piezography>Curves (your printer model) as well as in >Applications>QuadtoneRIP>Profiles>(Your printer model).

We haven’t deleted anything, only added.
