Patrick,
I will be outputting the images on laser transparencies, using bit
map, diffusion dither. I like the effect of the diffusion dither, it looks
less computer generated. My main area of work is photography. I have done
this succesfully in some alternative photographic processes (gum bichromate
and cyanotype processes) and have used it to print photographic images in
screenprinting. My original plan was to do Polaroid emulsion transfers but
the size that I want to use in my images is too expensive to do. I have
read Ceramics and Print" by Paul Scott and thought that the type of imagery
clarity that I want would be best done by silkscreening, image transfer or
decal. Color is an essential part of the imagery so finding the correct
pigments for color seperations is my quest. The "process" colors are the
closest to commercial printing inks used in seperations. I will try to
match Duncan EZ strokes to see if they make similar pigments. I would
prefer to have the image fired but will compromise if I can't.

Lisa,
Consider (if only for a moment) using gum bichromate for your project.
There's a slew of people doing color gum prints and I don't think it's much
of a stretch to suspend glaze stains, underglazes, enamels or glazes in gum
in place of pigments. D-Max and contrast range will be important variables
to control; there may be a question as to whether or not your printer can
produce the appropriate density in your negatives, whether for screen
printing or gum. I've done really cheesy experiments with using
Hunt-Speedball photo silkscreen emulsion as a medium, and it's worked, sort
of.
You might want to subscibe also to the Alternative Photo Process mailing
list. The FAQ is at:
http://duke.usask.ca/~holtsg/photo/faq.html
One of the list members,LuisNadeau, has been working on a book on photo
ceramics. His web page is at:
http://www.primenet.com/~dbarto/lnadeau.html
Oh yeah, Charles Berger (also a list member) has a process called
"UltraStable" that's apparently a lot like carbon tissue and Ann Perrigo,
when she taught at San Jose State, had a student who used the process to
fire a photo image onto clay. His web page (and I thought you'd never ask)
is:
http://www.ultrastable.com
Charles is in Santa Cruz, CA and might not be accessible to you.
Okey. Hope this helps,
Patrick
