Sprayout gun and discharge inks. I bet no one has done it.

[Screened Gear]

I had a small mark on a discharged shirt and decided to try to blow it out with the gun, why not try right.

Well it took the white right off. It did leave the clear discharged area. So then I thought maybe it was not cured. I went and got some shirts in the show room that have been washed. They looked exactly the same after washing them so the ink had to be cured right. One was white discharge and it did the same thing. Then a colored discharge, did the same thing. Both of these have been washed without any ink coming off in the wash (or enough that the color changed. Should I be surprised at this? Is this normal?

If you can, test one of your prints before saying my shirts are not cured. I really want to know if this is normal?

I don't exactly understand. Are you saying that you are surprised that the spray-out gun can blast away the discharge waterbased color, but not the discharged area?
Most spot cleaners say that they are good on plastisol and waterbased inks, so what's the surprise? You blew away all traces of the color component of the ink, and merely left the discharged fabric.

Frog,

I guess that is what I am surprised by. I guess I was under the impression that when you print discharge it dies the fabric and will not come off. I felt it should be just like using a sprayout gun on a red colored shirt. The red would stay. Am I really the only one surprised at this?

Even some shirt dyes will blow out. Try a pigment dyed or neon.

I've used the spray gun when I've gotten plastisol on a favorite discharge shirt, in the print area.
You can barely notice the spot I've sprayed out. It's there, but not like the pics.

On this particular shirt we were probably at ~80 saturation though. Big print area.

This has been known for a very long time, BTW. The pigments will blow out but theres no way you can reverse the dye dispersion. There is however a solution. I'll give you folks time over coffee to think about it.

Lots of water Tony ?

Nope but good guess.

Does Sharpie have a set of markers matched to standard ink colors?

gun does work if you do it before running it through the tunnel.
Otherwise, cover it up with plastisol . . .

No but Faber-Castelland Prismacolors have gotten us out of a jam once in a while. But thats not the solution I was talking about.

And Pierre nailed while I was posting. The only way to prevent this from happening is to prevent it from happening. Downside is some leaks are just plain hard to see before they exit the dryer. Good lighting around the press and closer inspection will help this.

I guess I thought that discharge was more of a die. Even plastisol will not come out so cleanly. I am a newbie at waterbase, I just showed that.

Jon, as I said, it is more like a dye, but still vulnerable to your spray gun.
