Q1: What is the main advantage of an inline waterproof varnish compared to an offline coating?
A: The primary advantage is production efficiency. It allows for immediate application and curing during the same press pass as printing, eliminating the need for a separate offline coating step. This significantly reduces turnaround time, labor, and handling costs while ensuring consistent, integrated protection directly from the press.

Q2: How effective is the waterproof protection, and what common substances does it guard against?
A: It provides a high level of functional protection by forming a continuous, resistant film. It effectively repels liquid water, moisture vapor, and grease, guarding against water spots, ink smudging, and fiber swelling. This makes it suitable for products exposed to humidity, condensation, or incidental spills, though it is not designed for prolonged full immersion.

Q3: Are there specific press settings or drying requirements for optimal performance?
A: Yes. To achieve its full waterproof properties and prevent blocking, proper drying is critical. We recommend using the press's infrared (IR) and/or hot-air dryers at recommended settings to ensure the varnish is fully set and cured before sheeting or winding. A test run to optimize coating weight and drying parameters for your specific substrate is always advised.
