I have my 2200 and R2400 running side by side for comparisons. The R2400 using the Epson supplied profiles for Enhanced Matte are superior to the 2200.
B&W on the R2400 is yards better - no color casts, rich blacks.
Moab Kokopelli Glossy printed on the R2400 using Moab's profiles from their web site are beautiful. They look like glossy photos. When I angle the print to the light, the surface is smooth, no hint of ink build up or metamerism. Again, this is much better than the 2200.
Now I can't wait for Colorbyte Software to upgrade ImagePrint 6 to handle the R2400. This is the one thing I miss as compared to the 2200. IP for the R2400 should be out in a few weeks according to the developer.
