Metallic Narrow-web Cold Foil
Cold foil can be transferred to the surface on a web-fed or sheet-fed printing press in line with a cold foil unit/module. On the printing process, the cold foil is adhered to a substrate first and over-print by the CMYK stations of the press, thus creating any color in metallic finishes. Cold foil is a high-speed process whereby the foil is bonded to a UV or conventional ink, so there is no need for a stamping die.
A narrow-web cold foil from Univacco is designed for labels, also applies perfectly on packaging with wider web-fed cold foiling press models, such as UV flexographic printing, UV web-fed offset printing, and UV web-fed letterpress printing. The over-printable narrow-web cold foil, Univacco CF4.6 Series, provides high gloss, a stunning metallic visual outcome from fine definition to a broad area. Univacco CF4.6 Series are available for wide a range of label applications such as personal healthcare, cosmetics, shrink sleeves, and in-mold labels (IML).
The narrow-web cold foil CF4.6 Series supports varied substrates by doing sophisticated surface treatment on corona and primer, which allows different printing parameters adjusting on the printing plate, the UV coating weight control by anilox roller, and the nip roller pressure. The CF4.6 Series is cost-efficient on good adhesion with UV ink and glue, less UV Glue loss.
