If you’re delving into the world of custom-printed tin boxes, you’ve likely come across the concept of varnishing. But what exactly does it entail and why is it so important for your product? This comprehensive guide will detail the numerous benefits and advantages of using varnish on your printed tin box, ensuring both aesthetic appeal and long-lasting durability.
Understanding Varnishing on Printed Tin Boxes
Varnishing, in essence, involves applying a clear coat over the printed surface of your tin box. This colourless and odourless substance offers high gloss, quick-drying capabilities, chemical resistance, and more. It serves dual purposes – enhancing the box’s visual appeal and providing a protective layer.
Key Advantages of Varnishing Your Tin Box:
Boosting Surface Shine: A well-varnished tin box will have an enhanced surface gloss, elevating the overall look of the printed content.
Increasing Durability: The varnish adds friction resistance to the printed matter, ensuring it remains scratch-free for longer.
Enhanced Special Effects: With varnish, you can achieve special effects like local UV, convex oil, and ice. These processes can make your tin box stand out from the rest.
Smooth Finish: Products such as playing cards frequently use varnish to boost the smoothness of the printed matter.
Moisture Resistance: Varnishing increases the moisture resistance of the printed tin box, safeguarding it from dampness and deformities, thus extending its lifespan.
Flexibility: A good varnish provides flexibility, ensuring that the coating doesn’t crack or break off.
Transparency & Color Preservation: A high-quality varnish forms a clear film over the printed surface, ensuring that the original colours remain vibrant without turning yellow over time.
Adaptability for Post-Printing Processes: Post-printing treatments such as stamping, hot stamping, and aluminium processing become more accessible with a varnished surface. The coating should also be resistant to heat and solvents.
Environmental Resistance: Especially crucial for tin boxes containing food, cosmetics, and other sensitive items, a varnished layer provides resistance against moisture, mildew, and other environmental factors.
Adhesion: Varnishing ensures the film adheres securely to the tin box’s surface, preventing any peeling or detachment.
Wear Resistance: The varnish grants wear and scratch resistance, especially vital given that tin boxes often undergo extensive handling during packaging and transportation.
Leveling & Smoothness: Varnish guarantees that the film surface remains smooth after application, irrespective of the printed material or graphic details.
Varnishing your printed tin box isn’t just about making it look good – it’s about ensuring its longevity, resilience, and overall quality. By understanding the numerous benefits of this process, you can make an informed decision to elevate the appeal and lifespan of your product. Whether you’re launching a new product or looking to upgrade your existing packaging, varnishing is a smart move for those seeking excellence.
