discharge and pinholes

[Prosperi-Tees]

Are you pretty much screwed? I thought about dabbing the shirt with black discharge and sending them back thru the dryer but never tried it.

we have successfully shot them out BEFORE they go into the dryer, On a related note, we have washed out entire plastisol prints by cleaning it with ink degradent, came right out. . damdest thing.

black discharge and black plastisol will NOT work.

Sharpie works for tiny holes. Sometimes using a spray gun will work as well.

If the pinhole is big enough and you catach it, you can spray it with water and use a white sponge to wipe it out.

Are you saying that you put in degradent in your washing machine in place of detergent?

[Homer]

no, we actually took the shirt off the press, straight to the washout booth and lathered it up with our ink cleaner, washed it out with the hose. . .came right out. . .that was a shot in the dark to see if it would work, it was a hoodie now that I think about it.

Make sure you inspect the screen very well before going to press.  Then make sure to inspect a test print very well before doing the run.

We use blockout pens if we have pinholes but typically we won't with our underbase screens anyway.

I usually tape the edges where the squeegee runs when running discharge. I ran a job by myself last week with plastisol and I did not catch the hole until 40 shirts have been affected. I just thought wow I'm glad this wasn't discharge!

Just be glad that the shirts weren't garment dyed like neons.

When we doing discharge we tape up our newmans so crazy, just to ensure we don't have any issues. Some shops might see it as a pain, but for us it's a precaution that i gladly take. Especially in really big runs.

Same here. I would rather waste a roll of tape than replace a dozen or more shirts.

Now I heard someone mention that taping the back side of the screen accelerates the break down of the emulsion. Any truth to that?

I think that could be true. Where I tape over my marks, if the job is more than a few hundred, the tape starts to fall off. I retape with a larger piece because you can feel the moisture under where the tape was. I've had to retape two times on a 500 piece run, each time expanding the area I'm taping to make sure I hit a moisture free area all around where the last piece of tape was. I'll try blockout next time to see how that compares, and add a random piece of tape off to the side and keep an eye on it to verify.

We try and omit reg marks from discharge jobs whenever possible.

When not possible, we place them above and below the image far
enough that we can move the print limits to avoid them after registering.

your using blockout pens for pinholes running waterbased inks?

Absolutely! Works for us as well. One or two colors why bother. And you can block them out with emulsion before reg and line up to film before you put ink in. Goal is to use as less / be as efficeint as you can in regards to our tape. Well, everything really. But man, tape is pricey!
