Digital BW, The Print

If, rather than buying a salesman's word (Tobie's), you actually visit
top tier museums galleries (as opposed to hobbiest koffee klatches)
you'll find that Epson OEM Ultrachrome B&W prints are more common than
dedicated B&W inkset prints. Real galleries often specify type of ink,
so you can confirm that if you care.

It's true that 2400 is easier to work with than 2200, and I've
recently moved to 3800 so I can use glossy paper, but 2200 is
magnificent for B&W on matte paper.
