When we need to underbase plastisol we use discharge. Much easier and cheaper. Less flashing as well.

I think my goal for this year has to be to learn this. My understanding is you underbase (using discharge) with screen 1. Then screen two will print the top color, etc. The print won't look bright until you put it through the dryer. At that point the underbase will discharge, leaving the top colors nice and bright as if printed on a light/cream color tee?

How much time does this need to be in the dryer for and what brand discharge are you using? I don't have a very long dryer and do not have forced/scrub air. I'm not sure if my dryer will be efficient for this.

Retention time depends on the efficiency of your dryer. Pretty much all brands work well and are priced similarly. You will need base (binder) and white. The mix ratio is up to you but don't use 100% white. Steam it off just a tic. Then plastisol on top. Once you get the variables worked out you'll be suprised how easy it is and how much your print quality will improve.

I'm definitely going to test it. It seems like this gives a much better quality, and saving on the flash is an very nice perk.

What do you mean when you say "steam it off just a tic"

Thanks!

Flash it for just a couple of seconds. You dont need it to completely discharge the base. The dryer will finish it off.
