Discharge underbase would be great if it worked on everything we print here, in the pass I've did a DC underbase with plastisol on top...I talked with my One Stroke ink rep yesterday and I might try using there water colour inks again, they suppose to give you a waterbase ink feel and print without the fuss of using actual WB inks. You would think I'd love WB inks since that's what I started out using when I first got into screen printing, put plastisol made me lazy LOL.
BTW my formula for DC/UB is usually 80/20 base to white DC INK (not pigment!!!) or 70/30 if thats not bright enough. Or you can buy a premix DC/UB which is pretty much exactly as above just pay more.
