Cold foil printing can be done two ways: the older dry lamination process common in the offset printing industry, or the newer, more versatile wet lamination process, which is dominant in the flexo label industry.
[1] Foil that does not adhere to the adhesive remains on a thin polyester liner, and waste is directed to a rewind spool.
It can be applied precisely with high resolution, even for fine structures such as raster gradients and thin lines.
Cold foil printing needs smooth surface substrates for excellent image quality.
[4] As the cold foil market evolves, major players in the printing industry are finding ways to make the process even more cost-effective.
[6] Cold foil is most commonly used on products that call for a strong "shelf appeal", such as household consumables, cigarette cartons, wine labels, and cosmetic packaging.
