SURFACE FINIHSHES

LAMINATING• This also produces a high gloss finish on card and provides good protection against

damage as it is normally water proof.The printed card is placed inside a plastic film/sleeve. It is then placed in the ‘in tray’ of a laminating machine which pulls the card and film through its heater and rollers. The heater warms up the film almost to melting point and the rollers press the film sleeve until it is sealed. When the card reappears in the ‘out tray’, the finished item looks glossy and professional. However, laminating is much more expensive than varnishing but gives more protection to the card.

EMBOSSING

VARNISHING

• VARNISHINGFine varnish can be sprayed on to the surface of card. When dry this gives a gloss finish and helps protect the printing underneath. The printing and colour work must be completed before this process takes place. Also, folding a package takes place after the varnish has been applied.Different types of varnish are available. The most popular are oil and water based varnishes. In either case, the varnish takes at least two hours to dry. This may be a disadvantage especially if the card is being used for a package - as it means it can not be folded straight away.

UV VARNISHING

• ULTRA VIOLET VARNISHESSpecial varnishes dry almost straight away if they are exposed to ultra violet light. (UV 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 / paper.

DIE CUTTING

• Die cutting or stamping is the process of cutting and creasing sheets of material. The die cutters are like pastry cutters mounted in a press which are then forced down onto a material. The main processes are:

• Cutting – separating the material completely• Creasing – making an indentation that will allow the

material to fold• Hole punching – making a window or an openingDie cutting is a fast and efficient process, replicating the

same shape over and over again. Paper card and sheet plastic can all be die cut.
