Paul,
I just recently acquired an almost new 1160 to dedicate to B&W. I ordered
the MIS UT-FSN ink set for it and I am using QTR to drive it. My first
question is; I saw one of your earlier comments about longevity problems
with an older version of the FSN inks. What do you think of the current
version? I am considering the Eboni/Carbon-6 inks although it would be
more rightly call Eboni/Carbon-4 in this case. So far, I am pleased with
the tone of the FSN inks. How would the Eboni/Carbon compare? What
dilutions would you recommend for a 4 color version? I would also consider
Jon Cones PiezoTone inks and I don't print a lot, so the higher cost is
not a significant factor.
Secondly, my first experiements have been on Red River Dourian Art paper
which has been discontinued by Red River. Too bad, I really like the
paper. Anyway, I have most of a 100 sheet box and I figure it was worth
using. I am using an overall ink limit of 75% with black boost set to 95%.
My ink partitions are 100, 47.5, 13, and 7. I printed the 21-step and the
Northlight test print. On the graduated circles on the Northlight test, I
got a beautifully smooth look. I measured the 21-step print with a
Colorvision spectrocolorimeter, plugged the values into QTR's
linearization, and reprinted the same tests. The prints were generally
lighter overall, with more separation in the dark areas. The problem is
that graduated circles now show some pronounced steps, not at all as
smooth as the un-linearized print. Have you seen this and what should I do
to try to fix this? I am not adverse to bringing the data from the .quad
file into Excel and trying to just lower all the points, except the very
black, by a given percentage. Would you think this is a viable technique?
I know it would require some experimentation, bu hey, that's why I got
this printer, to experiment!
Thanks,
Steve
