Wet litho overprint varnish formula (WOV) is a type of varnish used in lithographic printing processes to provide a protective and enhancing coating on printed materials. It is applied while the ink is still wet, hence the name “wet litho” overprint varnish. WOV offers various benefits to the printed materials and can be used to achieve specific aesthetic or functional effects. Here are some key features and considerations regarding wet litho overprint varnish formula

  1. Application: Wet litho overprint varnish is typically applied immediately after the ink has been printed, while it is still wet. This allows the varnish to mix with the ink and bond with the surface of the printed material.
  2. Protection: WOV provides a protective layer over the printed surface, helping to guard against abrasion, scuffing, moisture, and other external elements that may compromise the ink or substrate. It enhances the durability and longevity of the printed materials.
  3. Gloss and matte finishes: Wet litho overprint varnish is available in different finishes, including glossy and matte. The choice of finish can be used to achieve specific visual effects or match the desired aesthetic of the printed materials.
  4. Enhancing appearance: WOV can enhance the visual appeal of printed materials by providing a consistent gloss level, improving color vibrancy, and adding depth to the image. It can also enhance the clarity of images and text, making them more vivid and sharp.
  5. Special effects: Some wet litho overprint varnishes offer additional special effects, such as pearlescent or metallic finishes, texture or tactile coatings, or UV-reactive properties. These effects can be used to create unique and eye-catching printed materials.
  6. Drying and curing: Wet litho overprint varnish requires drying and curing to achieve its full properties. This is typically done using drying or curing ovens or through exposure to UV light, depending on the specific formulation of the varnish. The drying and curing process helps the varnish bond with the ink and substrate, ensuring proper adhesion and durability.
  7. Compatibility: It is important to ensure compatibility between the wet litho overprint varnish and the printing inks, substrates, and printing process used. Testing on a small scale is recommended to assess compatibility and achieve the desired results.
