I recently built a second JH Varislope filter and redid the panel. I'm still using paper on plastic for these but lately I've been using a laser printer on 180 gram glossy paper and it looks a lot better than my original attempt which was inkjet on plain paper. I also took the opportunity to change the text a bit here and there to make it more readable (e.g. "Clean" and "Dirty" vs. "C" and "D").
