Plate Oil is a commonly used ink modifier by heating linseed oil for specific periods of time to create various viscosities. It is available in consistencies ranging from the thin bodied #0000 varnish upwards to heavier bodied #7 varnish. Litho varnish may be used to increase the body of an ink when using a stiffer varnish or to soften an ink when using thinner bodied varnishes. |
