I'm using permaset Supercover and printing on gildan 64000 heater shirts.

I'm only printing basic words with no fill and a very thin stroke. Afterwards I flash it for around two to three minutes at 540 degrees or so from the flash dryer. Perhaps I'm letting it flash for long, considering There's very little ink being used?

I was trying to upload a picture of it from my phone but apparently the site is having trouble uploading it. Many thanks in advance!

....I bet this heather is shrinking while I'm heating it through an excessive amount of time. Hmmmm...... *squints eyes*.

You're lucky you didn't start a fire. You only need to cure for 30 to 40 seconds.

didn't the heavy black smoke give it away ? ya really your lucky you didn't burn your shop down. you just wanna do it long enough to dry it. are you flashing it so you can hit it with another color or white or to cure it fully ? flashing only takes about 10 sec. whoever told you to leave it under for 2-3 min needs to buy you a few shirts and a fire extinguisher.

Curing temp is about 400 degrees with a flash, since it's open and sitting an inch or so above the t-shirt.

I'm flashing to fully cure. I take it in context that I've been flashing for too long, thus shrinking the garment and wrinkling the ink? No one really gave a solid answer.

2-3 minutes is for water based and only to 320ish degrees. You are wildly over curing so yes. You're probably shrinking the shirt, scotching it, toasting the plastisol, and destroying the fabric and inks ability to stretch at all. Sorry your having an issue with it. Did you call or contact your ink manufacturer and ask them how to handle their ink with your equip?

My two cents. Toss them in a well and make a wish.

Ranai Shirt, you're flashing too long and your tempature is too high. Plastisol ink should be flashed around 5 to 10 seconds, and cured for 30 to 40 seconds at around 400 degrees. That's with cotton t-shirts.

Too make sure, contact your ink supplier as Hegemone mentioned. We don't know what kind of t-shirts you're using, what brand of ink, or which flash dryer.

We may all be a little sarcastic, but we're here to help. Sometimes we have to read between the lines.

man being a FF your lucky the house didn't burn down. Usually ink will cure around 320 and that is what union and triangle ink say. if you use metallic inks yes abit higher since they reflect heat. since we don't have a dryer yet we have to flash and dry with the same thing but even 400 will end up setting off the smoke alarm and yes we burned a bag.

Yes, that is what everyone is saying. I didn't have a conveyor dryer when I started and used the flash. We flashed to cure for 60 seconds. Once it got all heated up and running, 45 seconds. Flash dryer was placed about 1.5 to 2 inches above the garment. Be sure you have a temp gun (Harbor freight sells them on sale for $29 and everyday price is only $49). I bought two of them to make sure they both read the same. Your garment should get to about 350 or so to be cured fully by the flash dryer.

Seriously....the shirt wasn't smoking? I can't imagine keeping a shirt under the flash dryer for 4 minutes.

Hope it helps.

Ranai, isn't Permaset a Waterbased Ink? Just to make sure you should check with your Ink Supplier. Tell them you're using a flash dryer.

Also, Water based usually works best with Air. I did a few screen printed jobs with waterbased, I pointed the heat gun at it for about 10 seconds then flashed it for 30 to 40 seconds with the Flash Dryer.
