I use the following tools:
Epson SC-P800 printer,
K7 Special Edition Ultra HD MK inks,
Hahnemuhle Photo Rag Bright White paper,
QTR + QTRgui + PC Windows,
K7SpecEd-UltraHDMK-Master curve for the 3880 printer (as you have not published the Master curve for this ink on the SC-P800),
X-Rite i1Pro spectrophotometer,
Now I have a question for you: how to reach the Dmax 1.85 that you can get? (I arrive only at a modest L * 14.08)
First of all to determine the maximum black value obtainable with this ink on the Hahnemuhle Photo Rag Bright White, I print in QTR the test chart “ink calibration mode” with ink limit 100% and I get the maximum black value equal to L * 12.77
Then I print the 256 patch test chart for Colorport using QTR using the K7SpecEd-UltraHDMK-Master curve (only the one available for the 3880 printer and not for the new P800) and then re-linearizing two more times. I get L * 14.08 (that is a very poor value!)
So I ask you:
- Which parameters do I have to change in PPEv2 to get a Dmax 1.85?
- Can you send me a curve “built” by you for this card on a Sc-P800? Can you also send me the related PPEv2 file?
Thanks for the precious help you will give me.
