In an earlier thread Paul suggested I might have to relinearize my curve. I was preparing to do so (the curve is Eb6-PA-205 and I would save it under a new name) and when I printed out the 21-step file. I noticed that after the 70% patch, starting with the 65, the next 2 or 3 patches were abnormally lighter. Then, at 55%, they got darker again and the progression to white seemed more uniform. I think these problem areas might be what's giving me the solarized look. Those solarized areas in my print look to be the same shade of grey as in my 21-step print. Interestingly, this showed up more when the printer was set at 2880 ppi as opposed to 1440. (just to reiterate, am using a refurbed 1400, Paul's curve, and Premier Art 205 paper.)
However, when I printed the Calibration Print, the grey scale for each cart looked quite uniform.
Nozzle checks were excellent but I did the Epson's cleaning up to the third level just to be sure. But the cleaning routines did not help.
Is there a way to determine which cart or carts is causing that grey scale to have those problem areas? I do have a spare set of carts, maybe I should just replace all of them. Their chips have different version numbers so it might be best not to mix the two versions.
As an aside... do the mixed inks grow stale after a while? Just a thought...
I may need to provide more information, please let me know.
Thanks all!
Paul

In QTR when you press the "show curve" button in the Curve Creator you'll get a graph of the partitioned inks. Comparing that to the 21-step might tell you which ink is causing the problem.
