- One way that I like a lot uses a laser printer and clear overhead projector
- film transparencies. As always, MAKE SURE YOU'VE GOT THE KIND OF TRANSPARENCY
- DESIGNED FOR PHOTOCOPIERS/LASER PRINTERS, not the thermal stuff that will
- turn black and gum up your LaserJet.
-
- Anyway...what we've done is draw up the whole front panel, with all labels
- and markings for where holes will go, etc., using a graphics program, in
- our case AutoCAD. Then we use the software to mirror the drawing so all the
- text is backwards. Then we print it out on a LaserJet using the transparency
- film.
-
- Now...take your transparency and spray paint the side that has the toner
- on it. (Let it cool off first or it may smear.) After the paint dries,
- you'll have a piece of plastic where you can read your letters from the
- back side, only they read OK because you reversed them to start with.
- Obviously, you want to choose a paint color that the black toner will be
- visible against - we use gray.
-
- After the paint is dried, you can use trim adhesive or other glue to stick
- your front panel on. The way I prefer to do this is put on the label
- before I drill and machine the holes - that way my drawing can also show
- me the exact place to cut and drill. The downside is that the plastic
- layer can kind of gum up your drill and you sometimes have some ragged
- plastic edges to trim afterwards. Still - you end up with extremely
- durable, good looking labels, because the print is on the other side of
- the plastic and can't wear or wash off.
