Special varnishes dry almost straight away if they are exposed to ultra violet light. The varnish is sprayed on to the paper / card in the same way as other varnishes. However, after spraying the card passes underneath UV lights which dries the varnish almost instantaneously. One disadvantage is that this type of machinery is expensive to purchase. However, it produces an excellent gloss finish to the card or paper.Varnish is applied to card packaging in order to give it a gloss finish. It offers little protecting to the package and usually applied to give a ?shine? to the card. Varnish is also applied to pages of magazines so that they also have a gloss finish and gives the paper a quality feel.
