Q1: What is the primary purpose of this varnish, and how does it differ from a standard gloss varnish?
A: This varnish is specifically engineered as a primer for the mechanical calendering (hot pressing) process. While a standard gloss varnish air-dries to a shine, this coating is formulated to become plasticized under the heat and pressure of a calender, thereby enabling a much higher, polished gloss level and an exceptionally smooth, dense surface finish that cannot be achieved by coating alone.

Q2: What key benefits does it provide for the calendering process and final product quality?
A: It creates a uniform, receptive surface that ensures consistent heat and pressure transfer during calendering. This results in superior surface leveling, significantly enhanced gloss and smoothness, improved ink holdout (preventing sinkage), and a more luxurious tactile feel. It maximizes the performance and visual impact of the calendering operation.

Q3: What are the critical application and processing guidelines for optimal results?
A: For optimal results, apply a controlled, even coating. It is crucial that the varnish is completely dry (though not necessarily fully cured) before entering the calender. The calendering process requires precise control of temperature, pressure, and speed. Compatibility with specific paper stock and calender type should be verified through a pre-production test run.
