Flexographic printing is one of the fastest growing sectors in the printing industry. Our related research project examined the potential of matte varnishing as surface finishing process. Various surface finishing processes, such as various safety varnishes, protective varnishes, barrier varnishes, and the types of matt varnish we have chosen, are playing an increasingly important role in the development of today’s packaging material trend. In the course of the research, we tested the changes in the surface structure of the varnishing layer in the case of varying amounts of lacquer application, and we measured the gloss values in the case of the use of clichés with different surface patterns.

For the tests, we used a type of varnish developed by us, the critical required feature of which was a high degree of heat resistance, and in the development of which the biggest challenge was to achieve fingerprint resistance.

In the last few years, many product demands have transformed. The main requirement for the production of packaging materials has become a constant supply, constant quality and simple workmanship, one of the basic pillars of which is varnishing. Varnishes have always played a protective role, from which they developed into individual solutions. Today, most varnishes still play a significant role in mechanical protection, but processes have emerged that open up new opportunities for printers and also increase demand for their products. If the consumer sees a surface that seems interesting during a purchase, they will involuntarily step in to feel it. Just because the consumer grabs the products, he already evaluates them better they are more likely to buy them.

One of the leading trends today is the solution of highlighting logos or other important elements on products by treating the surface around them with matt lacquer, so that the brightly left area becomes dominant.

It is no coincidence that this technique has become popular, as the optical experience it provides has a really significant effect, directing the gaze to the right place the result will be clear but dynamic and special. In our opinion, the use of matt lacquer still has many possibilities. We have built our present research to explore these and apply innovative application techniques.
