We have a complete crap job that we have to run 2 sleeves and a front on Black Comfort Colors. Brian tested with the platiicharge and quick white 70% white 30% plasticharge with 6% activator. But I am not happy with the white. I want it brighter. Can I add some of the Extra white from my mixing system to boost the brightness?
-
I seem to remember back when I tried this stuff under the Wilflex Oasis name, whites were tricky and certain whites were recommended more than others.
You may need to talk to a tech.
(Oh, and get ready for a barrage of pure discharge fanboys questioning your choice, lol!)

LOL Thanks Frog! I make questionable choices daily!!
-
Maybe I am asking for to much? This is my result.
-
I thought you were only supposed to go up to 50/50 with plasticharge?
-
I started with 50/50 but could not get the opacity I wanted. I added some more quick to get 60/40 then bumped it up to 70/30 still with no joy. Ended up burning another screen and ran it p/f/p.

Two comments:
One you CANNOT add pigment to Plascharge - there are no binders to hold the pigment.
Second - using Plascharge on an opaques direct printing white is generally not recommended as it can get real gummy. All the "eye of newt" and "batwing" that go inot making these inks do not play well with plascharge. You are best to use a mixing white like Epic PF White. But it will probably not be super opaque.
Your best bet is to run Magna Super White straight for the best white with soft hand. OR run plascharge by itself, flash, and print a plastisol white through a real fine mesh (305) on top.
My $0.03 cents!

Personally I've never had much luck with plasticharging white. Other colors I've had decent results with but never white. We use quick as our normal white and our plasticharging results with it have been so so. If you can't get a straight waterbase d white to be bright enough I would suggest discharge base with a reduced quick white on top. I tried adding different whites with plasticharge as well as loading them with more opaque whites usually only to find an overly dry clumpy hard to print white. It would be straight waterbase or discharge base plus top white for us with our prior experience with plasticharging white. I'm sure others have had better luck though but we never had results that we worth much...
-
That white looks like crap. Is there a reason you aren't using waterbased discharge white? I may be wrong, but isn't there an issue using the comfort colors with discharge/plasticharge? Something with the dye they use not being fully reactive (I could be totally wrong).
-
comfort colors with the white tags will discharge, the one that the tag is the same color of the shirt will not.

Sounds like the difference between "garment dyed" and regular dyed.
