I learned this method from my Scottish friend Catherine Foster. It can be nice if you dislike the mess of chalk or graphite associated with normal pouncing.
First, draw your pattern, then go over it with a Sharpie marker so that your lines bleed thru to the other side of the paper. If using a plotter, pen-plot and go over the pen lines with a Sharpie. Then, go over the lines on the back of the pattern with a Stabilo pencil, using a color that will show up against your sign background. I have pen-plotted in reverse, but that makes it hard to see where the pattern will go. The Stabilo lines must be on the back of the pattern.
After you have your pattern all registered on your panel, make a few tic marks in the corners with a regular grease pencil, then remove it. (these can be rubbed off later)Then lightly spritz the substrate with plain old water (I've used Windex or Rapid Tac as well) Make sure to use a light even coat of fluid. Then replace your pattern, Stabilo-side-down, on your substrate. Squeegee or simply rub with your hands, transferring the Stabilo to the background.
The pattern will dry and can be re-used. You will get a good transfer that is paintable, instead of a big dusty mess and black mucus when you blow your nose. I can see the Stabilo easier than those tiny little dots from a pounce pattern, too. It may take a few tries to get it just right, as it can't be too wet or too dry. And of course, this method would only work on a glossy-painted or aluminum background.
