Durability is the first reason. Lamination protects the card from friction. Corners do not fray and the print does not rub off, so the card still looks new when an uncoated card has worn out.
Aesthetics is the second. Gloss makes colours brighter, while matt gives a soft, non-reflective surface that reads as premium. Either finish makes the design look deliberate rather than default.
Functionality is the third. Laminated cards resist water, smudging and tearing on the surface. They survive better in pockets, events and daily handling, and keep the card in good condition.
We have printed business cards in Petaling Jaya since 2008, and lamination is still one of the most popular finishes, requested for its value.
