This specialized alcohol-based varnish is engineered for high-gloss calendering processes, delivering exceptional surface smoothness and brilliance under heat and pressure. Rapid solvent evaporation ensures quick setting and optimal receptivity to calendering, resulting in a polished, mirror-like finish with enhanced depth and clarity. Ideal for premium packaging, luxury publications, and high-end labels, it combines efficient drying with outstanding gloss development for superior aesthetic and tactile quality.
Q1: Why is an alcohol-based varnish particularly suitable for the calendering process?
A: Its rapid solvent evaporation allows the coating to set quickly, forming a stable, receptive film that can withstand the heat and pressure of calendering without sticking, blocking, or losing gloss. This ensures smooth processing and maximizes the development of a brilliant, polished finish.
Q2: What results can be expected from calendering with this varnish compared to standard gloss coatings?
A: Calendering with this varnish produces a significantly higher, more uniform gloss level and an exceptionally smooth, dense surface that cannot be achieved by air drying alone. It enhances color vibrancy, improves ink holdout, and provides a premium tactile feel.
Q3: Are there specific application or drying requirements before calendering?
A: Yes. Apply a controlled, even coating weight and ensure complete drying (typically aided by moderate heat or air flow) before the sheet enters the calender. Inadequate drying may cause sticking or gloss inconsistency. Optimal calendering temperature and pressure should be determined through testing with your specific substrate.
