See, there you go. BKF Rives is not a watercolor paper. I have seen it used for drawing, lithography, intaglio, screenprinting, relief printing, linocut, woodcut, and collotype. It was never sized for watercolor - it would buckle badly.
A lovely paper, but not a watercolor paper.

Guess we have a terminology difference so I need to clarify.
I do digital reproductions for several watercolor and acrylic artists.
Almost to a tee their choice of paper for inkjet reprints are on Canson BFK Rives.
From the samples we have printed this gave the look and feel similar to their originals.
