I started with the UCpk-raw-neutral curve for the x900 series Epson printers. After going through the advanced calibration and linearization process, the linearized prints have very smooth gradation, deep blacks, and excellent detail.
However, the color of the print drifts noticeably highlight to mid-tone to shadow.
Other than trial and error, are there any methods for creating accurate and consistent toner curves? I have spectrophotometers and related color management s/w, so more advanced processes would be doable.
