If the total coverage of offset inks is anything above 20% of the card, the overlay film can only be laminated to a certain degree. Thus, when working with multi-layer cards, we recommend using the water-based bonding agent, AquaPress® CA, which can be applied by screen printing. Thereby, both different types of plastic and offset inks can be laminated with an overlay film.
Bonding agents can be supplied as AquaPress® CA LT (laminating temperature approximately 100°C/320°F) and AquaPress® CA HT (laminating temperature approximately 130°C/266°F).
In particular, gold and silver color shades as well as inks with special effect pigments are applied by screen printing in the production of cards. Here, good printing results and adhesion in compound values are achieved with the solvent-based screen printing ink NoriCard and the UV curing ink NoriCure CCI
