Varnishing is a process in which a clear coating is applied to a printed surface in order to protect it from wear, tear, and environmental damage. This clear coating can be either glossy or matte, and is typically applied using a roller or sprayer.
Varnishing is an important step in the printing process, as it can extend the life of your printed materials and make them more resistant to damage. It is especially important for materials that will be exposed to sunlight or other harsh conditions.
There are two main types of varnish: UV-curable and solvent-based. UV-curable varnish is cured using ultraviolet light, and is the more common type of varnish used in printing. Solvent-based varnish is cured using chemicals, and is typically used for outdoor applications or for materials that will be exposed to high temperatures.
Varnishing is a process that is applied to printed materials in order to protect them from dirt, fingerprints, smudging, and other types of wear and tear. It can also give printed materials a glossy finish that makes them more eye-catching. Varnishing is typically done after the printing process is complete.
There are two main types of varnish: water-based and oil-based. Water-based varnish is made from acrylics, while oil-based varnish is made from polyurethanes. Each type of varnish has its own advantages and disadvantages. Water-based varnish is less smelly and dries more quickly than oil-based varnish, but it is also more expensive. Oil-based varnish is less expensive but takes longer to dry and has a stronger odor.
Varnishing is typically done by hand, although some companies offer machine varnishing services. When varnishing by hand, a brush or roller is used to apply the varnish to the printed piece. The piece is then left to dry. Once dry, the varnish will have formed a protective layer over the printed piece.
Varnishing is an important part of the printing process because it helps to ensure that your printed materials will look their best for as long as possible. It is especially important for materials that will be handled frequently, such as business cards, postcards, and brochures.
