Digital BW, The Print

These Red River papers are loaded with OBAs. Their Premium Matte just
explodes off the page with color intensity and the illusion of greater
tonal range due to the ultra white (bluish) white base. The designers
love it for this reason. If they don't care about longevity its their
work. I wonder if Red River with this rag paper is taking Hahnemuhle
stock and coating it themselves. Can an OBA be added to a paper during
the receptive layer coating process or does it have to be done in the
initial paper making procedure.
