There is usually a trade-off between degree of rub off and dmax, with both the paper and spray. H. Photo Rag has great dmax, but if you look at the 100% black wrong it'll be damaged. On the other hand Premier Art Smooth fine art 205 (aka Epson Premier Art Scrapbook) has a modest dmax but is much more resistant to rub-off.So, I'd first try to find a paper that, by its nature, protects the pigments relatively well. Printing a 100% black patch and rubbing a finger across it to see what works best is probably worth the effort.With respect to sprays, I'd use the aerosol acrylic types. Lascaux Fixativ (non-UV) (buy from an art outlet like Jerry's or Blick) decreases the dmax of matte papers the least. Premier Art's Print Shield is a more typical glossy-photo type spray that has a more pronounced effect on the dmax. These are the two I use the most. Again, once you've decided on a paper, I'd test the 100% black to see what the best compromise is. I'd probably go for the Lascaux due to it's limited impact on dmax.Again, however, I doubt you'll find GO gives you any significant protection.Good luck with the book.Paul
