The roll stencil I am linking to isn't a photo paper...it is just a one or two shot stencil paper. You place it in a typewriter with a backing piece of paper and with the ribbon removed ( or an old tractor feed, daisy wheel printer with the ribbon removed) and type the needed words. The blue resist will come off on the backing paper in the places that were impacted. Cut off the stencil from the roll and use it with your etcher as normal.
If not using a typewriter, just use a smooth tip stylus of some sort. A small ball tip leather word detail tool works fine, as does a piece of round nylon, wood, etc. Just shape like a pencil with a smooth and round tip. The styli that you use to write on tablet devices work great. Temporarily tape the stencil to a piece of printer paper and write the mark wanted with the stylus. Lift off the stencil and the unwanted resist stays behind on the paper, creating the mark on the stencil.
The third way to make the stencil is to place a strip of printer paper over the stencil as well as the piece under it. Write or draw on the top paper with a ball point pen ( use heavy pressure). The roll has 20 feet, so you can practice all you want until you get it down. This material is great for a single use mark or drawing a simple logo. You can also make a signature mark well with this material. The stencils will make about five knives at the most.
