Thanks, but, no, that's not the issue. I can get the actual file to install the profile but for the fact that the file has a circle and a mark through it and when I try to open it, I get the error message that it is only for PowerPC Macs. I got a reply from Epson that they are not supporting this printer with Intel-compatible profiles (of course, Intel processors have been in Macs since 2006!).
Also, I don't get true black in my B&W photo prints (usually on Epson Ultra Premium Presentation Matte) for which there is no exact icc profile either. Using all Epson inks. Very frustrating.
It is an ICC profile, there should be no hardware issue. A profile simply provides tables to map input colors to a standard space, and then from that to your output space.
And as Ken points out, any decent lustre paper profile made for your printer should work just fine. If you want to find a better match, have a look at Ernst Dinkla’s Spectrum Viz; you should be able to fine a good match in there somewhere.http://www.pigment-print.com/spectralplots/spectrumviz_1.htm
