how long did you have the heat gun on the shirt!you might have to go over it for a few mins as it needs to reach a temp of 320 deg!you will be better off with a flash unit will save you a lot of time

 

You will have difficulty reaching the necessary 320 degrees over all the print for the full depth of the ink layer with a heat gun. If this is just a hobby, try a 350 degree oven for about 5 minutes or so. Otherwise, at least a flash dryer will be necessary. God Bless.

 

Curing with a heat gun is possible but unpredictable at best. You need to stay in motion (so not to burn the shirt) AND get all the ink up to 320 degrees from surface to garment. If your plan is to do any tyoe of production you will need to at least get a flash dryer.

 

Can you fully cure a T shirt with a heat gun?

Let me throw another question at you: could you start a taxi service with a motor scooter? The answer is yes, but you would be under-equipped. For your issue, you will will almost never get a uniform cure over the whole design. Also, the bigger the design gets, the more difficult it gets to cure. I would invest in a dryer, or at minimum, a flash.

 

Great way to put it ggraphics. =) And absolutely so true. Just because you can, doesn't mean you should. Invest even in a small flash dryer, and you'll do exponentially better than trying to dry with a heat gun.

Seeing that I wasn't being productive in answering your question, I went back and did a search. Although I don't condone this curing method, some of these threads may help you out.

Thanks for the info. I will have to do some more tests using the heat gun seeing as a flash dryer is far too expensive for me at the moment. Does anyone know if an Iron would act in the same way as a heat press? Or is it not hot enough?

 

If you think a flash dryer is too expensive. then maybe you shouldnt be printing shirts.

 

Not hot enough. Between the iron and the heat gun, you'll probably have better luck with the heat gun. Good luck.

 

Is there a self curing addative that may help cure for full washability? Or is this just for water based inks?

 

Plastisol has to get up to around 320, its the way the ink works.

Ok So I have tried a few tester T shirts to see how best to cure it with the heat gun. It turns out about four minutes across the whole design was enough to make it smoke and after a very very slight initial fade in the first wash; the second wash did not change the density of the colour. Although there was a slight fade it was nothing like my initial t shirt which noticably washed out. Thanks for the advice everyone
