Probably not necessary with HSA, that stuff has the best matt down of any ink. I don't even knowif it would work, it doesn't seem to have that compressible quality that plastisol does.Are you putting both whites under the grey?
i wouldn't try it w a quartz dryer personally... but you you can buy a low cure additive. im about to buy a bigger dryer / more chamber, just so we can handle this ink properly
