Digital BW, The Print

Sorry, I re-read your post more carefully. A standard ICC profile for the
3800 will dither colour ink into K since it expects a brown/green Epson K.

Still, using Jon's Selenium for PK, MK, LK and LLK would make it an easier
job to create QTR profiles in a 17", dual purpose printer scenario.

Jon, would a gloss overcoat be required in this scenario?
