Digital BW, The Print

Hello all!

I am slowly getting into 'more serious' black-and-white printing
(since I sold some prints). I outsource larger sizes, but I print most
of the work on my Epson R800. I recently began 'toning' my files with
PS adjustment layers, and now with Nik SilverEfex (which I like a good
deal).

Here's my problem. My monitor is profiled with Spyder2 Pro. I believe
the profile to be very good. Known files look correct on screen, and
most importantly, a greyscale step wedge looks neutral across the
range from white to black.

Color images print very accurately on the R800, using the latest
manufacturer's profiles. Neutral b/w images (with equal RGB values
throughout) print neutral to very, very, very slightly cool. (In wet
darkroom terms, about CC 02 at worst.) BUT the 'toned' files print too
cool, and skewed at times toward a rather nasty purplish tone in the
mids. This tone is most visible under my D50 Ottlite, but also shows
up in daylight/incandescent as well. (I guess this is 'metamerism'.) I
note that, looking at the RGB numbers in the file, the on-screen
display appears correct.

So what can I do to get a better screen-to-print match? I don't have
the budget for a spectro, and I'm a bit leery of profiling with a
scanner (but would try it). 

I am also considering converting a 1280 I own for strictly b/w work
using the MIS carts. This would undoubtedly get me consistent
reults--and clogs--but it would remove the 'toning' I am doing.

TIA,
Les
