Hi guys and thanks for all the good tips and techniques...

Someone talk about warming/heating up the ink. Would put it in the microwave works? Or how do you actually heat it?
I'm going crazy with these white ink on Dark... the ink i'm using is so much thicker than the black for example.

I also have this problem with the white ink peeling/taking the fibre up/away from the garment...
Could it be because the ink is too thick?

I guarantee you it will work better than that heat gun. There is a company or two that passes along the heat gun ignorance to help sell their equipment(it isn't slamming if it is true!)and I just in one sentence told you a better way to do it(halogen). Better yet...a few seconds in your oven(while still on the platen)under the broiler element is even better for flashing. Please EVERYBODY....toss that heat gun!!! It is just one of the erroneous things that is aimed at noobs to hold them back. 'Doable' yes...but you can also dig your way to Australia. If nobody told you we have jets. I am amazed at how many people are putting up with the spotty and time consuming use associated with heat guns. I have taught a LOT of people to print about everything and I would never tell anyone to use a heat gun. because I know better. I suspect those who told you you should knew better too. Make it easier on yourself. LOSE that heat gun. You will feel MUCH special'er' if you do.

Thanks for the tip! I did 20 shirts last saturday and had to do the backside prints the following day cause it took so damn long to cure with the heat gun. You will have converted another person if I can get it to cure with my halogen light! How long is a typical cure time on a single color logo, say about 10"x10" ? Thanks very much!

Sorry to bump this tread but i thought someone would have responded to some of the queries see the amount of experts on this board.
As the tips has been brought up, i was wondering 'how' to warm up the plastisol?
Can you use your microwave or is there another technic (easier and better than just mixing it by hand)

Thanks

Remi

I never liked microwaves, and don't trust them, besides the can could get very hot to handle.
However another way of heating the inks could be by filling a pan with hot water,putting your tin inside and slowly stir till creamy.
Just my opinion.

That pretty much covers it....jeff

Good info thanks!

The problem with them is that they have a limited area of effect, so it's impossible to be sure you got the required coverage.

If the flash unit is too hot you could accomplish the same thing by turning it down.

I wouldn't use the microwave, it might work but I ain't ever going to try it. All I ever do is just stir the ink for a few minutes to loosen it up. I work in texas so I don't have to deal with cold ink very often. When is does get cold, I'll put the ink on top of our conveyer dryer or flash unit for a while till it heats up a little.

Actually I like mine. I tried using the halogen lights to dry a shirt and it was taking way too long. I would rather have a flash dryer but I dont have the $$ for one. A heat gun works perfectly fine and is cheap. Thats why people buy em. Although I dont recommend one for large quantity runs because its a lot of work once you get over 25 shirts. My back was killing me the other day. But every shirt was cured perfectly. They are great for beginners with little $$ like myself =]
