Abstract
A drying agent particularly suited for facilitating the drying of inks and paints includes a cobalt drier that is more than six percent cobalt by weight, and no more than fourteen percent cobalt by weight. In particular, the cobalt drier is twelve percent cobalt by weight. The drying agent can also include a manganese drier, tung oil, a water-activated drier, a two-way drier, and a lithographic overprint varnish. All ingredients can be present in the mixture at a concentration of one part by weight. The drying agent can be used with a variety of printing stock substrates, and may be used at significantly higher concentrations than prior art drying agents.
