What is the best process for curing Fabric Opaque Screen Printing Ink by Speedball?
You can hang your work in the sun, maybe iron it, some people put their work in a dryer, time usually cures paint on fabric though. You will never wash out any ink you happen to get on your best tee shirt! Try out a sample piece before you go any further, iron it, put it in the dryer, then wash it and put it in a window to test wash and lightfastness.
