Digital BW, The Print

Hello,

Thanks for posting the instruction files for the Quadtone installation
and Linux.  I am using Gentoo linux, and, with a couple of small
variations, the instructions were very helpful.

Here is what I have:  Gentoo Linux, Epson 1280, MIS VM inks, and Epson
archival matte paper.

Previously, under windows, I used Paul's 4 curves which ranged from
cool to warm.

I noticed, when I pull up the print GUI in linux, that I now have two
curves, which came as part of the standard install:  one is called
Gray, and one is called Toned.  I am assuming that I need to mix these
in some ratio, but I am not sure how to balance these to get something
approximately like Paul's cool -> warm curves.  Can anyone give me
advice from here.  Will I likely have to make any custom configuration
of curves, given my hardware/ink/paper choices, above?  What is the
best method for testing these curves, and what am I likely to have to
tweak, and where?  :)

Thanks for any comments.  Previous comments were helpful, when I
searched through the archives of this forum.

Hi Jeff,

You will need both curves. When you bring up the quad print menu you can
see at the bottom that there are three choices that have to do with
this. The first is the proportion of each curve you wish to use, 100%
gray to 90% toned. You will have to run some tests to see which mix
works for the image you are going to print. The next two chocies select
the the two curves. Set one for the gray curve and one for the toned
curve. You will have to replace one of the files that Roy included,
toner-curve.raw, since it is designed for the Mac not Linux. If you
like, I will send the Linux version to you. It will need to be placed in
the example inks folder. You will need to reprocess the two curves with
run-quad-profile after you install the linux version of toner-curve.raw.

I use MIS VM-sepia with an 860 and it is really nice to be able to have
almost unlimited control of the toner.

Jeff,

The builtin curves for 1280 with VM are really just starting examples.
You'll need to go thru the calibration procedure to get the best results.
Read the info files in CurveDesign -- that should get you started.
