A couple questions off the top of my head:1. Are you sure the printer was working properly before you installed the carbon inks?2. PC or Mac? If Mac, what OS X version, and are you using PrintTool?There are others who I’m sure can be of more help than I, but your answers to these questions will be useful.~ Keith

I've used qtr with carbon based inks in the past for quite awhile but having some problems now. I had two different Epson 7800's fail on me over the last year and so have had little opportunity to much printing. I finally picked up a third 7800, made new carbon inks based on Paul Roarks recipe, Installed it all, recalibrated my monitor, made new paper profiles using a colormunky and linearization it all, but getting very unsatisfactory results. What comes out of my printer is quite a bit lighter in the mid-tones to the shadows; particularly the shadows ..... not the blackest black per se. Can any one of you out there offer any insite? Could it be that I just goofed up the darker ink dilutions when I originally made them. Anybody got any ideas. I've included a link here that should take you to a page on my site where you can see a visual representation of the difference I'm experiencing. My website is below and you should see the page titled 7800/QTR test in the menu selection on the right side of the screen.

Thanks again for any helpful tips.

For Windows, see pages 10 - 11 of
Note the difference in the curve for QTR v. Gray Gamma 2.2. The monitor may be displaying the image using the Gray Gamma 2.2 profile (same gamma as Adobe RGB) while QTR prints a straight line response. The print will look lighter, particularly in the shadows.
The workflow does depend on the platform.
