Should a printed surface receive an additional coating? This thin protective layer is known as “varnishing” (or “coating”). While similar to lamination, it involves a completely different process. This article explains the varnishing process so you won’t confuse it with lamination when making a choice.
How do varnishing and lamination differ? Lamination involves applying a plastic film, offering superior protection, increased rigidity, and better water resistance. Varnishing is thinner, more eco-friendly, and lower in cost, though it provides less protection and rigidity. Choose lamination if high protection is required; choose varnishing if environmental friendliness and cost-efficiency are the priorities.
The choice depends on three factors: environmental requirements, desired gloss level, and the level of protection needed. Opt for water-based varnish for eco-friendliness, UV varnish for high gloss, matte varnish for a specific tactile feel, and lamination for robust protection. Combinations are also common; consult your manufacturer about available options before deciding.
Water-based varnish is the primary eco-friendly choice. It uses water as a solvent, is environmentally friendly, and is highly recyclable. It offers moderate gloss and is frequently used for food packaging and orders with strong sustainability requirements. Its low cost makes it a standard choice for high-volume packaging.
Varnishing involves applying a layer of varnish to the printed surface and drying it to protect the ink and enhance either the glossy or matte finish. It is thinner and more versatile than lamination, allowing for either full-surface or spot application. With favorable cost and environmental profiles, it is a common post-printing process.
UV varnish is the go-to for high gloss. Cured by ultraviolet light, it offers intense shine and excellent abrasion resistance. It also supports spot application to highlight logos and graphics. While more expensive than water-based varnish, it is ideal for packaging that requires a brilliant, glossy finish.
Matte varnish is all about texture. It creates a matte, anti-reflective finish that looks understated yet premium, making it popular for dark-colored packaging and minimalist designs. Combining a matte base with spot gloss creates a classic, layered look—a concept similar to pairing matte lamination with spot UV.
