This is the best printer that I have ever used and has delivered some fantastic results. The pigment inks are a boon for print longevity and the colour accuracy out of the box was near as dammit spot on.
The level of detail afforded by the 1.5 pl ink drops is astonashing. This combined with the wide colour gamut helps produce digital files which rival and in most cases beat those from film.
This is a truly first class printer, the speed is impressive (if not as fast as Canon's- but then higher quality offsets this) and the results speak for themselves. There is minimal metamerism and bronzing is all but eliminated with the inclusion of the gloss optimiser cartridge.
The results are good on Epson paper, but I prefer using Ilford Gallerie smooth pearl paper. It has a nice weight and suits the printer. For matte prints the Epson papers- especially archival matte, are hard to fault.
Being ultra picky the black and white results could perhaps be improved with a colour profile, but for most people including pros, the results are fine.
If you are considering buying a printer, ignore this at your peril.
