Abstract
A method of producing a printed structure comprising the steps of: (i) providing a substrate; (ii) subsequently printing one or more coating layers of direct food contact (DFC)-compliant overprint varnish (OPV) onto a first side of the substrate, wherein the DFC-compliant OPV comprises no more than 2.0% by weight of any colorants relative to the weight of the OPV.

A method of producing a printed structure comprising the steps of:
- (i) providing a substrate;
- (ii) subsequently printing one or more coating layers of direct food contact (DFC)-compliant overprint varnish (OPV) onto a first side of the substrate, wherein the DFC-compliant OPV comprises no more than 2.0% by weight of any colorants relative to the weight of the OPV, wherein the OPV comprises a silicone release agent, and
- wherein the silicone release agent is an acyclic polydimethylsiloxane (PDMS), and is present in the printed structure in an amount of 1.0 to 47.0% by dry weight of the OPV layer and wherein the printed structure does not comprise siliconated paper.
