hi, I use Methodology 3 to print digital negative for Two years and have the Piezography Digital Negative inks installed (with shades 2.5 and 4.5)，P2M-PZDN-X800-Meth3-1_8v3.quad is curve I used ,my print is EPSON R3000.my Alt-Process is palladium print.I only have a scanner,did not have Spectrophotometers or Film Densitometers .Now I want to try PiezoDN。
I read your F.A.Q,they said use Meth3 curves inside of CURVES/PZDN_to_PiezoDN,which curve I should use? PiezoDN-X8-Meth3-1_8v3-P2 or PiezoDN-X8-Meth3-1_8v2?
I also read a way to calibrate PiezoDN with the 21STEP_SCANNER_TOOL Excel file. can I use the curve above that I choose .then linearize my .quad? can you give me more information about how to converte from from Methodology 3 to PiezoDN .
