The Epson Stylus Photo R2400's prints are worth it, though. First, Epson has resolved several notable problems it had with the SP2200's blacks on glossy paper, including a gloss deficit, bronzing, metamerism--colors appearing differently under different light sources, and the tendency of all the inks to show scratches. Unlike the R800 and R1800, which apply a gloss overcoat for consistency, the R2400's UltraChromeK3 droplets are encapsulated in the glossy resin. The new inks are higher density than the old--Epson says they achieve a maximum density (Dmax) of 2.4D compared to 2.2D for the old inks.

As long as you print using the Black and White color-matching in the Epson driver, monochrome prints look great: sharp, with little metamerism and a broad tonal range that includes nice tonal separation in normally problematic shadow areas. Though the R2400 prints black-and-white using both composite gray and the dedicated black inks, the driver seems to throw too much cyan into the mix when treating grayscale as color and thus requires more extensive custom profiling. Since the driver surfaces the Black and White option only when using a select set of papers--Premium Glossy Photo Paper, Premium Luster Photo Paper, Premium Semigloss Photo Paper, Matte Paper-Heavyweight, Watercolor Paper-Radiant White, Enhanced Matte Paper, Double-Sided Matte Paper, Velvet Fine Art Paper, and UltraSmooth Fine Art Paper--you'll have to do some serious faking and tweaking to use that mode with other papers.
