I was comparing prints of the same negative made on Arches Platine and Fabriano Artistico Extra White, and, in addition to greater d-max, Platine was somewhat sharper and cleaner in the shadow separation. I imagine that the increased sharpness would be due to the smoother surface of Platine, and a wondering if there is anything I could do to Atristico (post-acidification) to make it smoother. For what it's worth, I am using the back side of the Artistico because it has a more random texture than the side with the water mark. Does anyone know what Platine in sized with that gives it a smoother, denser surface? I am going to try to put a sheet of damp Fabriano in the drymount press prior to coating to see if that helps any. I love Platine, but the price per sheet was starting to take its toll on my wallet, and am now trying to make the Fabriano work for me.
