Digital BW, The Print

Hello:

After lurking for some time I decided to try BO printing with an Epson
c84 and the MIS Eboni.  However, before doing this, I printed a test
image using the standard Epson inks, both using all inks, and then
just BO but with the Epson ink.  Then after swapping the black cart
with the Eboni, I printed the same image, BO.

I like the full ink Epson image the best.  It's much smoother and dark
shadows have more detail than the other two.  Dmax seems the same
between all of them.  It's neutral, so no worries there.  I know, it's
not archival. 

Oh yeah, the paper I used is just the Epson Heavyweight Matte, as
that's all I have right now.  But it's an apples to apples comparison,
and I'm a little disappointed in the Eboni.

This was a surprise to me.  Should I go with the full MIS ink b/w
inkset?

(side note:  I've always used Quark to print with.  Worked fine on my
old Epson 780, but with the C84 all images have a course halftone
screen applied to them.  Printing from PS works fine, but I like to
print from Quark as I can put text photo descriptions (time,place,
etc.) under the photo, and still have crisp text.  PS rasterizes the
text, at least PS 7.0 does.  Any ideas here?)

Thanks,

Mark
