I’ve set up a new 3880 and have tested it successfully with Epson inks. I ran flush fluid through to make sure all the Epson inks were vanquished (till the nozzle checks showed no signs of color other than the red of the flush). I’ve recharged it with Piezography inks and tested it (with the lineariztion checker) to see if it is producing linear prints, which it is not in some cases.
So, what I did was to check both the custom curves that Inkjet Mall made for my original 3880 and the MPS curves from the glossy curves library. I tested JC5 and Epson Exhibition Fiber. They yield quite different results. Here’s a link to the linearization screen shots:
For the EPexFiber, both curves seem to my untrained eye to make unacceptably dark greyscale ramps. On JC5, the MPS curve looks pretty good (tell me if you disagree), and the custom curve seems to be too dark.
Question: Is this a curves issue, or some other issue? I’ve done lots of shaking of the carts and inks in bottles before starting on the most recent part of this adventure.
If we think it’s an ink issue, I’ll buy a new set of inks - these are three years old. If it’s a curves issue, I’ll make new targets and have new curves made. I could also do both.
If I’m totally off, let me know.
