Paul,
I do have two versions of K-0-40 one with and one without the Black Boost...
There should not be a black boost in the K-0-40 curve. I've never made one like that, and it makes no sense to have a boost for what is supposed to be a straight line curve from 0 - 40. Push the "Show Curve" button in the QTR Curve Creator to check the curve.
both show Dmax for several steps on the black end of the step file.
I don't know why your 1400 with Eboni MK would hit its dmax on PA 205 at such a low level. Over the years I've profiled a lot of Premier Art 205, Epson Scrapbook, and PA 325, all of which use the same coating, and the Eboni MK, PA 205 (and related paper) Epson 1400 dmax has always been hit between 45 and 50. I think quite a few people have used these profiles with success.
As for creating a new profile, at this point that's over my head.
Have you tried the Epson driver? See the PDF for settings. Eboni-6 is compatible with the Epson driver.
... I have a question about the profile you sent me a while back. I had expressed some concern that the .qidf for PA 205 used only one cart firing, the rest remaining idle.
Yes, a clear base in any un-used positions is highly recommended.
So you sent me a new profile which including firing the five remaining carts, it was called Eb6-PA-205.qidf.
It is for Eboni-6 in the 1400. I thought you had Eboni-6 installed in your printer now.
But when I printed with that profile I got a rather pronounced Sabbattier, or solarization effect on a file I've never had trouble with, even with the R1800.
Either a jet is not firing or the inks are not Eboni-6 -- or maybe your printer is just not working correctly.
Good luck and Happy New Year.
Paul
