Not sure if this is an on-Topic post, but thought maybe someone here may be
able to recommend a way to grab an image via a photo and using photoshop
make a stencil or impression of sorts for a stereo indicator dial on glass
where the letting came off:
You gave me an idea, which might be workable. Print a reverse
stencil/background where everything is black and transparent,
lettering being transparent. Then back that up with whatever white
color you want. It might even be possible to simply paint the letter
color if the chemicals don't allow the image to run.
So perhaps: Print a reverse image on a transparency. Spray paint the
transparency, and see if the toner runs (or not).
Plan B: print as above, back it up with a piece of white paper or a
white painted object (like another transparency painted white). The
result is exatctly what you want.

Some trophy shops are able to print the plates that are attached to trophies
as well as engrave them. They generally use what's called sublimation
printing. I don't know if they can print white - think maybe not - but they
could print black over a silver colored plate and you'd be left with silver
(pretty close to white) numbers.
So if you make a Photoshop of the dial in black (or whatever you want) and
leave the numbers clear (white?) you could get a plate printed and you could
then cut it out and smooth the edges. Maybe that's one way to at least get
close.
Also, I don't see why they can't print on glass... tho printing on a
relatively small round piece might be harder than printing on a larger
rectangular plate. You could being take a piece of glass and the dial to one
and ask. Test on the glass plate before risking the actual glass dial.
One drawback to this... the printing isn't quite as crisp as you might want
if you inspect it closely. Then again, it isn't expensive either.
Hope that helps.
HEY! Come to think of it, they should be able to print on a copper PCB as
well as on those metal plates they use. Might be some possibilities there for
printing a PCB mask for etching. But I don't think you'd want to do 3 mil
traces with 3 mil spacing. Biggest question in my mind would be their ability
to print exactly 1:1 from the file they're given.
