Research of the Factor that Influence the Glossiness of Water-Based Tipping Paper Gravure Varnish
In order to prepare high-gloss water-soluble gravure varnish which is used on tipping paper, different content and types of filming resin with different content of all kinds of additives added are used to prepare water-soluble gravure varnish. Test its main performance and then use IGT apparatus to proof. The effect of varnish component and content on glossiness of water-soluble varnish is discussed by measuring glossiness of proof. The results show: different content and types of water-soluble filming resin have a great influence on the glossiness of water-soluble gravure varnish which is used on tipping paper; the glossiness of water-soluble varnish film can improve by adding auxiliaries such as cosolvent, substrate wetting agent, flow agent, wax emulsion and other promoter into water-soluble varnish system.
