Peter, I added readings to the chart for the Epson 7800 so you can see them side by side with the R3000. As you can tell, there are a few significant

Kerik, The color of the negatives should be green. The Y and C gives green, and PK and LK merely darken the green. I read a maximum density (through)

Sandy, OK, thanks. I’m working on it. A couple more questions. What do your negs look like? Are they quite green? Also, with the profile you gave, do you
RE: UV transmisison characteristics of Epson K3 inks
2014-03-05 by <sanking@...>
So, K=10, Y=25, C=25, LK=25. Like that? Yes, just like that. After you install the profile have a look at the curve in .quad view and it will be clear why it
Re: [QuadtoneRIP] RE: UV transmisison characteristics of Epson K3 inks

You would need to find a percentage (Level) for MK that matches more or less the UV blocking of C and Y. In my profile, where the K = PK, the current values

Yes, I am using PK in the profile. Not much has been said about this method for digital negatives. As I mentioned, I got the idea from Mike Rosenberg

Hi Kerik, The profile should print on the 3800/3880 with QTR almost the same as it prints with the R3000. I use the same profile, with just a minor adjustment,
