I received my little cube of Versafine and I figured I may as well test it, even though I thought it would probably perform pretty much like the Ranger Archival, since they are both oil based.
But no. See pics below. It really performed much better. Some of the leaf detail is not as crisp as on coated CS, but I think this image is acceptable. And done on the same Canson Aquarelle 90 lb. I did all the others on.
I think I can get a little better detail if I use the stamp upside down and paper on top method.
I'm still going to get some Daler Rowney to try. But I have to say, the Versafine out performed the Ranger, the Palette Noir and the India Ink.
I could not resist comparing my Memento and the Palette Noir to Versafine on WW card stock and the difference in blackness is striking.
