I use mylar a lot in cyanotypes -- for drawings, composting images and textures
and so on.
Results of xerox-on--mylar vary, but I find I need to assess this right at the
copy shop -- it is possible to get dense images but you have to fiddle with the
xerox settings. These days I'm testing putting mylar through my home printer to
create negatives from PhotoShop -- so far though, those negatives haven't been
dense enough, probably because I have an inkjet printer not laser printer.
