Help with Heat-setting speedball-fabric paint
This thread has been closed and archived.

I need some serious advice about heat-setting speedball paint. I have water-soluble paint for block printing. I've been using it on fabric and it comes out nice however when I wash the fabric it runs everywhere. I've read online that you can heat-set it but I've tried leaving it in a clothes-dryer for over 30min and I've used the oven at 300degrees for 10min.
Any advice would be greatly appreciated..

I've only heat set regular rubber stamp ink, so the only thing I know is that a) it works best on 100% cotton fabric and b) heat set it with an iron before washing it. Wait til it dries, and then press it with a cloth between the ink and fabric. I use paper towels.

Speedball has a printing ink and a textile ink. I would be sure to use the textile ink (which is also water soluble, when wet) for your washables. I heat-set mine with a hot, dry iron after the print has thoroughly dried. I just use a plain old piece of printer paper as a barrier and iron for about 3-4min!

peaseblossom is absolutely right about the fiber content of your material! If you are not printing onto a natural fiber, that could be the problem. Otherwise, you could try a new tub...maybe you got a dud!? I have great success with Speedball, but I've also heard good things about DickBlick & Jacquard, if want to try another brand. They all have slightly different consistency & 'open' time, but you will find one you like!

hey all! :)
water-soluble ink will almost always run when washed, regardless of how you heat set it :(
definitely try speedball fabric or textile inks. they will bond with the fabrics, making them more permanent. then make sure you heat set for at least 5 minutes and up to 250 degrees. this causes a chemical reaction in the ink that makes it actually permanent.
i use an iron to heat set all of my shirts with a piece of brown butcher paper between the iron and the shirt, and have never had any trouble :)
hope this helps, and hope everyone is having a wonderful day! :D
