Wet litho overprint varnish formula is a varnish used in lithographic printing to provide a protective and enhancing coating on printed materials. It is applied while the ink is still wet, giving it the name “wet litho” overprint varnish. WOV offers several benefits to printed materials and helps achieve specific aesthetic or functional effects.
key features of wet litho overprint varnish formula
- Application: Apply wet litho overprint varnish immediately after printing the ink, while it is still wet. This allows the varnish to mix with the ink and bond with the printed material’s surface.
- Protection: WOV forms a protective layer over the printed surface, guarding against abrasion, scuffing, moisture, and other external elements that may damage the ink or substrate. It enhances the durability and longevity of printed materials.
- Gloss and Matte Finishes: Wet litho overprint varnish is available in glossy and matte finishes. Choose the finish to achieve specific visual effects or to match the desired aesthetic of the printed materials.
- Enhancing Appearance: WOV improves the visual appeal of printed materials by providing a consistent gloss level, enhancing color vibrancy, and adding depth to images. It also clarifies images and text, making them sharper and more vivid.
- Special Effects: Some wet litho overprint varnishes offer special effects such as pearlescent or metallic finishes, texture or tactile coatings, or UV-reactive properties. These effects help create unique and eye-catching printed materials.
- Drying and Curing: Wet litho overprint varnish requires drying and curing to reach its full properties. Drying or curing ovens or UV light exposure typically facilitate this process, depending on the varnish formulation. The process ensures proper adhesion and durability of the varnish.
- Compatibility: Ensuring compatibility between the wet litho overprint varnish and the printing inks, substrates, and printing processes used is important. Test on a small scale to assess compatibility and achieve the desired results.
