Printing waterbase over discharge ub

[Doug S]

I know that you can't use 100% white disharge and print plastisol over it and expect it to stick but what about waterbase?  Do you have to dillute the white discharge ub before printing a waterbase color on top?

Hmmm I've printed 100% DC base white and printed plastisol on top, and it stayed on, I've did a few wash test, but could be I didn't do enough test but we've never had anyone bring them back.  Might have gotten lucky

Doug, 100 percent white will work if you can flash to prevent build up and your colors muddying up but I would NOT recommend the 100 percent or the flashing. a 85/15 base/wite mix does the trick for me. also it really helps to use chino base in your overprint colors ith 160- 200 mesh. of course thats relative to what kind of mesh your using. I also like the 70/90/70 squeegie durometor but again it depends on your press and your printing technique. why not just run straight up discharge?

I appreciate the replies.  I wanted to straight discharge both the white and the red but I can never seem to get a good Red by mixing pigments.  I ended up discharging the ub and printing red plastisol over.  I didn’t dilute the white base with regular base.  I just ended up flashing for a rediculous amount of time.

I’m wash testing tonight.  Hopefully, everything is good or I will have to reprint.  At least there is only 35 of them if the wash test doesn’t pass.

the ABSOLUTE best red on the market is the sericol . Hands down straight out of the bucket  they make 2 shades

your wash testing should be fine if you fully flashewd the base

I appreciate that.  I'll have to give it a try. 

I'm going to a class for waterbase in July.  Something tells me, I'll leave there with a little more knowledge and wishing I had a longer dryer.
