OK, the transparency is a single use item. You don't iron it on,
because that puts a layer of something (goo) on the board. Of course,
there's the glue you use to hold it on, but in that case, you have a
choice of what to use. You reverse it so that the printing is on the
bottom, and won't be easy to wear away. Goes on the top of the board,
of course.

You laser print on the back of the transparency, that's the SS layer.
You could just as easily go color with transparency film and an ink
jet.
