This paper is OBA free; yet it has an unusually low Lab B -- slightly negative according to my spectro. Apparently Canson claims to add some "natural minerals" to achieve this whiteness. Does anyone know what they are adding?
I profiled the paper for the 7800 and Eboni-6. It has a good dmax and prints on the warm side, with a maximum Lab B of about 5.
