I have been using the 7800 for all of my own work for the last few months, but I am preparing to teach a workshop in August where we will be using Epson 2200 printers. I spent the day creating the same type of profile I have been using successfully on the 7800. It uses mostly black and light black, but adds a little color at the highlight end with the yellow ink to boost the UV density slightly, and a little cyan and little magenta to enhance smoothness.
This profile is a good illustration of a point we were discussing last week about the maximum density needed to print pure Pd with no restrainer. You will see that the 100% negative value (0% white on the print) checks in at UV logD of 2.97! And I have also added some visible and measurable density as low as 2% negative value (98% on the print). I used the same target print densities that I linearized in the 7800 profile, and then eyeballed in some tweaks. This profile, for me, in my conditions, prints a 50 step tablet that mimics the look I have on my calibrated monitors. I hope it does for you.
To use this profile , follow all of instructions that Ron Reeder has so generously loaded onto his website for using QTR. Put this profile in the 2200-Create-profile folder, and run the script to add it to the 2200 profiles. Edit your file in Photoshop, invert to a negative (command-i on the mac) and then flip the image horizontally. Pick the QTR2200 printer in your print dialog, , choose this profile as your #1 ink profile, then choose 2800 dpi and uni-directional, and if you feel like it, you can click the advanced mode and choose adaptive-hybrid dither. Note that you do not have to add a curve to your file. It is built into the driver, in 16bit mode, no less.
Print it on Pictorico and then print the negative with no restrainer. You may find that you need some extra print time with this profile, because I have intentionally added some negative density in the shadows that is not present when using some other methods. IOW, your minimum time for maximum black may not quite be enough. A test strip may save you some time here.
Good luck. I hope this is useful.
P.S. The attachment manager here will not let me upload a file with the extension .qidf on it. This is a .qidf file that has had the extension manually changed to .txt. After you download it, you will need to change it back to UC2200Pd.qidf!
