Detailed Explanation

The cold foil process begins with screen printing a UV-curable adhesive in the desired pattern. The adhesive is partially UV-cured to a tacky state. Metallic foil (typically aluminum with a gold or silver finish) is then pressed against the tacky adhesive using a nip roller. The foil transfers only where the adhesive was printed. A final UV cure fully hardens the adhesive, bonding the foil permanently. Excess foil is stripped away as waste.

Compared to traditional hot foil stamping, cold foil offers several advantages: no heated dies are needed, setup time is shorter, and it can be integrated inline with screen printing. CooPrinter's fully automatic UV screen printing, curing, and cold stamping production lines combine all steps in one continuous workflow, achieving output speeds of 300-500 pieces per hour for gold and silver cardboard, packaging, and label applications.

The global screen printing market, growing from $7.44 billion in 2025 to $10.23 billion by 2034, sees increasing demand for decorative effects like cold foil in luxury packaging and brand differentiation. CooPrinter's integrated cold foil solutions help packaging producers achieve premium metallic finishes with reduced material waste and faster changeover times.
