I still go plastisol on these because I know it's durable, no worries about penetration and who cares about a supremely soft hand on a canvas tote right?
But I would be into running WB on it. Our standard WB colors are simply unactivated mixes of Sericol Texcharge right now with some odd quarts of matsui laying around. I'm sure that will change as we adapt WB to more substrates, explore higher solids WB inks like the HSAs, etc. but, does anyone print standard opacity WB colors on canvas? How's it work out, any better/worse than plastisol?
