What is Scratch-off Varnish?
Scratch-off varnish, also known as scratch-off ink or scratch-off coating, is a special type of varnish applied to printed surfaces. It consists of a layer that can be scratched off to reveal hidden information or graphics underneath. This varnish is often used in conjunction with games, promotions, or security measures to add interactivity and enhance user engagement.
How Does Scratch-off Varnish Work?
Scratch-off varnish is composed of a mixture of polymers and solvents that create a thin and flexible layer on the printed material. It is applied using conventional printing techniques such as flexography, gravure, or screen printing. Once the varnish has dried, a metallic layer is applied on top, creating a reflective surface. The scratch-off area is then coated with latex or acrylic ink, which covers the hidden content until it is scratched off.
