No, I'm not recommending JPSS as a superior dyesub paper, I was just pointing out that it can be used with sublimation inks as well as dye and pigment inks, which is something often overlooked by users of JPSS.
I'll be honest and admit that I mainly use it on drawstring bags which are rarely, if ever, washed.
Maybe pigment inks are the best of the three methods regarding washability but I'm not in a position to try them as I don't have a pigment printer. Has anyone tried JPSS using both sublimation and pigment inks and done a comparison?
