One of the ingredients in the process of mixing varnish is coconut oil &amp;amp;ndash; used to produce black offset printing inks which were the subject of testing issues in order to compare with commercial offset printing inks. Based on the results of research, the best formula for mixing varnish was 50 of coconut oil, 36 of phenolic resin, and 14 of solvent oil. At the same time, the best formula in producing black offset inks was mixing varnish with 20 of coconut oil 20. Consequently, the result of testing of properties of coconut oil based solvent offset printing inks regarding viscosity, tack and ink flow, showed that offset printing inks with oil based solvent had the properties less than commercial offset printing ink. Additionally, the result of testing also indicate that the rate of properties in aspects of ink spread and setting time of coconut oil based solvent offset printing were higher than that of commercial offset printing inks. </abstract> <index>Open Science Index 93, 2014</index> </article>
