Speedball Oil Base Block Printing Inks are waterproof and permanent. They clean up with kerosene, mineral spirits, or turpentine. Consider the use of non-toxic turpentine substitutes for clean-up. The inks themselves are non-toxic, and conform to ASTM D 4236. Colors are intermixable. All colors are available in 1.25 oz (37 ml) tubes. Note — Use this color chart as an approximation of the real color. If exact color matching is necessary, use actual samples of the materials. |
