Thibaud, Larry, Mac, and all,
I've tried an experiment using some quite white drafting film and laser
printing. I converted
the sundial file to a bitmap and then filled all the white area with a light
grey. This way there
is a fairly uniform layer of ink all over the sheet and the shadow of
murals and allows you to remove graffiti. But I know this stuff is

In the polyester family of products, the printing industry uses a variety of
types known for their linear stability under tension, pressure and heat.
Here is one source that I googled under "photopolymer plates." There may be
some inspired use here because of the imaging capability of these plates.

Thanks for the suggestion.
Alas, in my tests, an azimuth cylinder sundial with a laminated paper
dial face does not have a good light/shadow boundary. I have

Thanks, John,
I'm sure Mylar is great for certain applications, but doesn't work at
all well for mine. I seek a durable material for use on a cylinder
azimuth dial, where the sunbeams form two light/shadow boundaries,
one at either side of the cylinder. I've tried Mylar, clear plastic,
and pl
Use Mylar!!!
This is a translucent stiff milky white plastic paper. Your local blueprint
shop can plot onto Mylar. I use it a lot. (it cost more than bond paper
however). You can get it wet and it won't shrink, expand, or tear and the
ink does not wash off except with acetone. Great Stuff! I us
