Re: digital negatives and Epson printers

I don't think you "have" to use a RIP and an all-black inkset -- but I think
if it so happens that you are also making Black & White inkjet prints using
this method it would make more sense than constantly changing ink carts and
purging the printer, or dedicating a printer. The RIP method(s) with
seven-different-tones-of-black will typically use one or more of the
lightest inks in the lightest shadow areas, then combines four or more inks
in the mid-tones and then again uses two or more of the blackest inks to
create highest densities. Whether or not this yields better "detail" in the
final print is still a subject for debate, or may not matter depending on
some of other variables (read: paper or the process). In the end "a dot is a
dot", if the density is made of a bunch of varying tones of black dots as
opposed to a bunch of varying tones of coloured dots may be six-of-one and
half-a-dozen (or K7) of the other.
