Paper and board finishing.

Paper and board finishing

Finishes are applied to paper and board to protect the surface and/or improve its visual and tactile quality. The finish should be chosen for the product: a menu needs a durable wipe-clean surface, while luxury packaging may prioritise appearance and texture.

Lamination

Encapsulation seals the whole document inside polymer film or a pouch. This gives strong protection from dirt, spills and handling, but adds polymer material to the paper product.

Film lamination bonds a thin polymer film to the surface. It is useful for products such as menu cards where a wipe-clean, more durable surface is required.

Liquid lamination applies a clear liquid coating and is used for applications such as large-format signage.

Embossing and debossing

Embossing forms a raised design in the paper or board. Debossing presses the design below the surface.

Both are mainly used to create tactile and visual detail rather than to provide major protection. They are useful for greetings cards, branding and premium packaging where the surface itself contributes to perceived quality.

Varnishing

A clear varnish can enhance colour and give protection against fingerprints and moisture.

UV varnish is cured rapidly using ultraviolet light and can produce a smooth gloss or matt surface with good resistance to abrasion and chemicals.

Spot varnish is applied only to selected areas. The contrast between varnished and unvarnished areas can highlight a logo, image or other feature without coating the whole surface.

Foil blocking

Foil blocking uses heat and pressure to transfer a metallic foil onto the substrate. It adds colour, reflectivity, texture and a premium appearance, so it is commonly suited to decorative packaging, cards and branding rather than products where surface protection is the main requirement.

Choosing a finish

The designer or manufacturer should consider the required protection, durability, appearance, application method, production cost and end of life. A polymer laminate may make paper much more durable in use, for example, but combining paper with a polymer layer can make material separation and recycling more difficult.
