Anyone have any experience with making layered PDFs? I mean, I've done it before, but I have a PDF with 22 layers in it, and it's PATHETICALLY slow. I'm not sure if it's something about the file that Scribus made for me, or just that it's got so many layers.
All my layers are made of 8.5x11" PNG files that fill the whole page. Is that an issue? Would the performance be dramatically better if the images were smaller? Seems like it'd be a pain to line things up.
Advice is welcome. The alternative would be to make lots of pages of single-layer PDFs. I'm guessing a 20 page PDF with layers for just the registration marks would be faster than a 1 page PDF with 22 layers.
