What's the best method for making registration markers for multi-color poster printing?

Currently, I am printing registration marks on my transparencies so that they burn into the screen. Each registration mark is the same for every color. When the screen is burned, the registration marks appear. I clamp the screen, and lower it to print the registration marks, then lift it and cover them with tape. I use the printed marks to line up my paper. This works pretty well, but I am convinced there has to be a better way. Can anyone help?

the way you say is industry-standard - if you think, or get told, of a better way, you'd have more bucks in the bank than letters in a very large dictionary - so if anyone knows purrr-leeeze pm the solution! ;-)

That's pretty much the traditional solution -- use the registration marks to line up for the next print run, use that to transfer alignment marks for the page edge, optionally place some sort of physical stop in place at some of the edges so the page to be printed can be reliably slid into place (definitely important for large runs), proof, adjust if needed, print the production copies. This is assuming, of course, that your screen is hinged at one end so it always prints in the same place. That doesn't work well for fabrics, of course. In that case, the solution I've seen is a transparent overlay of stiff plastic, hinged on one side (eg with tape), which is printed onto (or, in some cases, is the transparency the screen was burned from), aligned with the screen. Use the transparency to align the material, flip it aside on its hinge, print, repeat. When you're designing your print job, remember that letting print regions overlap a bit avoids gaps. I've seen some gorgeous nine-color and higher silkscreen runs which took full advantage of that, selecting the order of print to make sure that the details printed in an order that minimized alignment and coverage problems.
