Water-based varnishes: on paper. When applied to paper, water-based varnish serves several purposes:

  1. Protection: It provides a protective layer over printed materials, such as brochures, posters, labels, and packaging, safeguarding them from wear and tear, moisture, and smudging.

  2. Enhancement: Water-based varnish enhances the appearance of printed materials by adding a gloss or matte finish, making colors appear more vibrant and text easier to read.

  3. Durability: The varnish makes printed pieces more durable, extending their lifespan and ensuring they remain in good condition during handling and shipping.

  4. Resistivity: Water-based varnishes can offer resistance to fingerprints, dirt, and other contaminants, which is especially beneficial for items frequently touched or exposed to various environments.

  5. Environmentally Friendly: Water-based varnish is a greener option for paper coatings, as it emits fewer VOCs and poses fewer environmental and health risks compared to solvent-based alternatives.

  6. Quick Drying: Its rapid drying time is advantageous for high-volume printing operations, reducing the time needed for post-printing processing.

  7. Flexibility: Water-based varnish can be applied to specific areas or patterns on paper, allowing for creative and design-specific effects.

When using water-based varnish on paper, it’s crucial to consider the paper’s weight, finish, and porosity to ensure proper adhesion and the desired level of gloss or matte effect. Additionally, printing professionals often use dedicated equipment for varnish application, ensuring a consistent and uniform coating.

Water-based varnish on paper is an excellent choice for a range of printed materials, offering protection and visual enhancement while maintaining an eco-friendly and safe approach to printing and finishing.
