I'm sorry to keep asking this, but I still don't understand why you would consider going to bitmap (which would add another step and subtract valuable information from the file) even for a quickie gum demo or for students, since in the same post, you reported and showed that printing the inverted channels as a regular greyscale works well for tricolor gum, even on cheap transparencies, just as I've been reporting and showing for years. So I'm still just puzzled, why would you go to bitmap if you didn't need to.

Sure, if you wanted to explore the different effect of bitmap printing, but that's not what you're saying here; you're saying bitmap would be a good choice as a quick way of getting gum negatives, and I'm saying that doesn't make sense to me, since leaving the file as a greyscale is even quicker and works at least as well (with your printer) if not better (as with my printer).
