I just removed a wad of paper and fixed it in preperation for some Cyano trials and the Agfa paper has a visible watermark on the rear (when wet anyway). Should be interesting to see if its visibleafter coating etc.
I am going to try emulsion and fibre side.
By the way, is Agfa Brovira a RC paper?. Feels really plastic!
I tried this on the gelatin side of fixed-out RC paper, which doesn't have the problem of sensitizer soaking into the paper. The cyanotype came out very sharp, but density was low.
just double coat and you will get the good density
