Labels with varnish fluorescent

Labels printed with security features such as invisible fluorescent varnish. The best and cheapest solution that meets the security function is varnish that glows blue under UV light. This is a specialist solution at the customer’s special request. There are also special types on the market, such as thermochromic paints (which change color under the influence of temperature), coin paints (which change color when rubbed with a coin), or black IR (allowing IR rays to pass through). For economic and technological reasons, securing products with invisible printing is only gaining momentum in Poland. Printers must have specialized equipment and certification to be able to print and control it.

APPLICATION: An example of the use of labels with invisible printing are: wrap-around labels on bottles in Germany, which are printed with a special fluorescent varnish. Such protection prevents such labels from being counterfeited. All this is because the product, which is a plastic bottle for drinks, is subject to recycling and a deposit is returned for its transfer.
