Speedball Retarder Base

Use this stuff to slow down the drying time of printing ink. Why would I want that, you ask? Because if the inks dry in your screens while you are off getting a sandwich you're gonna have a really bad time.

Use 1-2 tablespoons of Retarder Base to 8 ounces of ink and that won't happen!

If it does, we got you covered; check out Speedball's Speed Clean for help in getting that screen clean. Beware, Speed Clean removes pretty much everything from your screen (i.e. screen filler, photo emulsion, etc.).
