Hello folks,

This posting is for those that design inksets such as Paul Roark, or
like me that want to come up with a particular shade of sepia.

My airbrush has been sitting around doing nothing for a while due
recent development in GLOP for glossy papers and roller applications
for matte media. I found a use for it last night when I was rolling my
own sepia shade and after getting frustrated a bit with the cotton
swab.

The airbrush spits out ink much like an inkjet and you spray it
straight from the mixing bottle. Using an Iwata Eclipse BCS with
adjustable spray you can spray it light, dark and anywhere in between
to simulate ink intensity with ease. Test spray on your target piece
of paper for accuracy.

I got now a sepia tone that I really like but it's still a tad too
reddish magenta. Maybe a few more drops of cyan will do. This was the
result of my spray test on a paper different than my target paper. And
the new 1160 spongeless cart just makes it so easy to reload ink.

I'm using this sepia not as a toner, but as a gray in a two-ink QTR or
IJC/OPM profile. Somehow I cannot get the tone I really like when I
use it as a toner in the profile.

In this 1160 setup I have MK in the black cart, PK in the cyan
position, the newly concocted sepia in the yellow, and perhaps I can
come up with another sepia in the magenta position for a paper that
doesn't work well with this sepia.

Anyway, the airbrush makes an excellent aid in ink mixing. I hope some
may find this information useful.
