Digital BW, The Print

We used to size BFK for gum prints and multiple registration silkscreens by dissolving a couple of small packets of Knocks Gelatin in about a gallon of hot water. Then you soak the paper for about 5 minutes and hang up to dry. It is a very good non acidic invisible but durable coating. The problem is you have to flatten out the sheets after drying. We used a dry mount press for that.

I tested a number of  the Arches and other brands of uncoated papers, the Arches Hot Press (and Cold Press if  you like texture) had the best dmax.  The watercolorists I work with like it for its relatively high color gamut.  It is more heavily sized and calendared than many of the softer papers.  Have you compared the 2 apparently different papers?
