This file is mostly my notes, but they ended up on Rec Scouting before they
came back here
I recently took a class in screen-printing and we used
a method not described in the above FAQ. The screens
are bought pre-coated with a thermal sensitive coating
on them. To make a screen, you put the paper artwork
behind the screen and run it through a thermal copier,
the kind that used to be used to make transparencies.
They're sometimes called "Thermofax" machines, but the
"fax" part has nothing to do with facsimile machines.
The screens themselves cost about $40 for a pack of 20
screens. As far as I know, they are only available from:
Welsh Products, Inc.
P.O. Box 845
FAX (the modern term:-) 707-745-0330
Advantages to this method:
Real easy - no emulsion layers to paint, no developing/
cleaning, no transparency/acetate copies
No developing table needs to be built/bought if you
have access to a Thermofax
Screens are not as durable. With careful use you only
get about 100 prints from a screen.
Thermofaxes are becoming hard to find. Regular copiers
nowadays copy directly to transparencies so there's
no need for a Thermofax. Local schools may still
have them. That's where I go. Used machines go
for about $400. I may try to look into some of
those office/computer junk shops. A lot of companies
are going under around here and that's where some
of there equipment goes.
Screens are only available by mail from Welsh Products,
at least around the NH/MA area. They are real easy
to deal with, though. And they do have supplies
for everything you need.
Screen material is not re-usable.
Cost difference: Dunno. I haven't priced photo-emulsion
material. Also the re-usability factors in. Of course
$2 per run plus pennies worth of ink per shirt is a WHOLE
LOT cheaper than the $20-$30 per run plus $1-$2 per shirt
from a t-shirt place.
I'll be using this method for our upcoming Troop t-shirts,
but I may try the photo-emulsion in the future.
Also, our frames were plastic, about the thickness of a driver's
license, and we taped the screen onto them with masking tape.
I don't see why this wouldn't work with the photo screens.
I may experiment with drafting tape. It doesn't stick as strongly
as regular masking tape, so removing the screens will be easier
and less potentially damaging to the screen.
Have a great Holiday season
