When I had problems with W&N paints in carbon tissue making last year I posted it to the list and somebody pointed me to a dissertation that described exactly what I was seeing. It could be pigment specific and not the entire line of paints. I use W&N paints for gum printing with no problems.

Carbon on Glass (Back Exposure).

........... I have used tube watercolors and powdered pigments. Winsor and Newton watercolors DO NOT WORK. They have a preservative that spontaneously hardens the gelatin as it dries.

thanks for your post, but I'm surprised about W&N. I use these products without problems.
