Speedball Block Printing Ink Retarder

When mixed with water-soluble block printing inks, Ink Retarder slows ink drying time while maintaining ink viscosity. It is ideal for low humidity conditions and allows artists more time to lay down their print. The retarder is water-soluble, non-toxic and cleans up with just water. Made in the U.S.A.

Available in a 1.25 fl. oz. tube
