Card ink: small areas, high wear resistance

Card inks differ from general packaging inks in three ways: they cover small local areas, and they must survive heavy wear. What gets printed on a card is often just a signature strip or a small metallic mark, but the durability demand is severe — a signature strip has to survive daily insertion and friction, and a metallic mark has to survive lamination heat and long-term abrasion. The cost of failure is also higher: not one sheet, but an entire batch of cards.

Signature ink has to satisfy two apparently conflicting requirements. Writing must take — the surface needs enough absorbency and controlled roughness for ballpoint, rollerball and gel pens to lay down a clean line. And it must not wear off — once cured it resists scratching, does not flake and does not blur the writing. We formulate to a specified pen type and abrasion standard, and offer an anti-tamper version that leaves visible evidence of alteration. The gold and silver series replaces hot stamping: single-pass printing eliminates the foil transfer step, lowers cost, and still allows gradients, halftones and fine lines.

Both are mainly screen and pad printed, suited to small local areas on cards, and can be combined with UV varnish for a uniform card surface. For laminated cards, please state the lamination temperature and pressure so the correct heat-resistant grade of metallic ink can be selected. Complete proofs including base print, metallic layer and varnish are available so lamination results can be validated before mass production.
