The purpose of this experiment is to find out if any of the papers have hidden dyes that might or might not effect the markers. To do this, I applied two drops of Various Ink Blender 0 to the paper to get it really saturated and hoped it would push out and reveal inks in the paper. So let’s get to it and see what I found!
Papers A, K, L, R and V all had ink in the papers and resulted in a purple-ish ring. L shows up the lightest but is darker than what is actually pictured. (Please note: I have updated and tested with X but didn’t retake the picture.)
Based on this test alone I would recommend B, C, D, E, F, G, H, I, J, M, N, O, P, Q, S, T, U, W and X to be the better papers.
