Set up a sheet to match your film, place your registration marks wherever you want, and save it as a template. You can have other items on other layers and in the preferences for those layers have them not print. The attached is the one I use. The heavy black outline, the blue "field" and the red guides do not print. The black outline is my pallet. The blue field represents roughly the "imagable" area of my film, and the guides are, well, just guides. I printed one out and have it on my set-up board with three registration posts for my screens to butt up against. All artwork, including Photoshop art seps, are placed on this template.
