Title: Discharge base ???
Post by: Maxie on October 27, 2016, 12:14:16 AM

I have a few questions about using discharge base.
When printing process can I use a water based discharge base?
Does this hold the dots?
When printing on dark shirts do you use a white discharge or clear with opaque plastisol?

our experience with discharge base is to use a clear and add white, but not too much; too much and the top colors, if using plastisol, may not stick well after a few washings... some of the other that do more of it may have the amounts of how much white to add to the clear...

we add 15% d-white to base. you can also add a small amount of pc white in place of the d-white. too much white will cause build up issues. remember a nice firm squeegee, 200 mesh minimum

Pro's and Con's for flashing the D-Base first or printing wet-on-wet?

SO TRUE. Our senior artist just brought me one and we decided to go with index INSTEAD OF DB AND 4CP. with wording and a highlite white your at 7 colors. with index its 8 but we will get a more vibrant print
