Lars / Herman,
I was victim of that awful yellow / green smearing with my R800 (some users claimed never to encounter it), and I'm pleased to say that the R1800 seems to handle them very much better straight out of the box. Epson claimed some gamut improvements in this printer over the R800, and apparently they created better profiles. I've found them to be more than adequate for most purposes, but there are a number of images where I need better fidelity in the skin tones, so I need a well-written profile.
Thank you very much for recommending Mr Rodney - I'll make contact!
