Digital BW, The Print

I just installed an Epson 4800 ( I got it for the price of a 3880 from
my dealer - I guess because it's so unfriendly to swap color and matte)

The quality of the b and w is on a par with Piezography -- and you can
vary the tint.

I don't know if there will be color shifts in different light. Could be.
Put aside the cost of the inks, and unless you are doing a lot of
dedicated B and W, the flexibility of having a color printer that prints
superb b and w is worth it. BTW I always found Epson inks letter cloggy
than others.
