Proell KG’s core business lies in the development of custom-made chemical products for coating/decorating plastics and other materials, as well as innovative ink systems for IMD/FIM technology, and screen and pad printing inks, which the company is showcasing at this year’s FESPA.

Among the new products is Norilux DC, a formable, abrasion resistant Dual-Cure screen printing lacquer. Norilux DC can be used as protective lacquer or hard coat on PC, PMMA, ABS and PP films.

Norilux DC is ideally suited for first surface coating/protection of products manufactured in IMD/FIM technology. The glossy version of the Dual-Cure lacquer can be printed on textured film surfaces to produce abrasion resistant and transparent display windows.

The matt version of Norilux DC can be printed on uncured transparent hard coat films such as Makrofol HF 278 or 312 to create matt and high gloss effects in one item. Besides the high glossy Norilux DC lacquer, various satin gloss, textured and matt grades as well as pigmented and UV-stabilized versions are available.

Tactile surface structures e.g. brush effects and 3D patterns can be printed with the highly resistant lacquer. The Dual-Cure screen printing lacquer can be used for overprinting silicone-free UV, solvent and water-based screen printing inks as well.

Norilux DC dries by evaporation of the solvents in jet dryers. Before further processing of the printed films, it is necessary to remove nearly all solvent residues from the layer of lacquer and substrate. Well ventilated box ovens can be used.

Films decorated with Norilux DC can be 3D formed after box oven drying e.g. by high pressure forming or thermo forming. Afterwards, the formed films must be UV cured. Depending on the thickness of the lacquer layer, UV doses of 1200-2000 mJ/cm2 are necessary (Kühnast UV-Integrator, UV 250 to 410 nm, max. 365 nm).

The cured lacquer layer shows excellent resistances to abrasion, chemicals and cleaning agents and passes various creme tests of the automobile industry. In automotive interior, center stacks, touch panels and decorative trims are first surface protected with Norilux DC.

Marketing Manager Director at Pröll KG Stefan Zah explained these new developments at the show.

“We are a traditional yet modern ink company that specializes in making inks for pad and screen printing. We make specialized inks for customers who have specialized applications, such as high temperature resistant inks up to 300°C for direct molding.”

“In the future, we will stay in our markets. We don't produce digital inks, so we'll stay in the screen printing market. This is a traditional business, which will remain our business. We don’t pretend to serve the whole market, but we have some special industries that are doing it really good, and this is the difference.”

“Inkjet might be a threat for screen printing, specially in the future. The traditional market for screen printing is really threatened about digital print. Of course digital printing is taking business from screen printing, but in our field, there are a lot of combinations to print both technologies together. They don’t have to be substitutes.”

“At FESPA we can meet a lot of international customers from all around the world. A lot of visitors have been today from Turkey, Poland, Taiwan and [other] different countries. It’s very good for us to be able to meet them in one place.”

“The future and the challenges pass through the quality and technology of the pre-press area. If pre-press is good, the industry of screen printing is productive. But digital market is improving as well. This is our challenge.”

“Our focus is to acquire inks that can be solvent UV or water-based UV. Those lacquers, transparent on matt, have very high resistance to chemicals, operations or scratches. In the future I guess we will produce even more lacquers than we do now.”

To optimize customer support, Pröll Services GmbH was founded as a subsidiary of Pröll KG in 1994. Pröll offers a broad scope of services for pre-press work, especially in the areas of screen stretching and stencil production. The staff is made up of certified printing technicians and experienced screen printers, and constantly improving and maintaining services on a state-of-the-art level is always a top priority.

“Customer service is so important,” Mr. Zah said. “We are very close to our customers.”

The company has developed an international reputation, with distributors in Japan and China. In 1998, the company opened Proell, Inc. in St. Charles, IL, which serves as both a central warehouse and service centre for the U.S. and Canada. A state-of-the-art lab makes it possible to fill a customer’s requirements promptly, which means even special colours are available in no time.

The requirements for screen and pad printers continue to evolve, and Pröll KG is right there to provide the expertise and service to help meet those needs.
