Digital Outback Photo have a good article on making black and white prints with the Epson 4800 and UltraChrome K3 inkset.

“‘All of the zonal values in the monochrome photographic prints produced by this combination of technology show with exacting precision. What I have composed on my calibrated Sony Artisan monitor is exactly what comes out of the printer—tit for tat. The Dmax of the prints is so deep that even under the bright lights of our gallery spots, the prints never wash out—the blacks only look deeper, and the whites brighter. The resolution of the print process has created image prints at 18” width, with more detail than I have ever seen in an entire 30”-wide fiber print. The dimensionality of the print has come to life because of the resolution, precision, and fidelity of this new print scheme.”
