Omet is touting its Varyflex V2 as a flexible narrow- and mid-web press for packaging printing and converting. The Varyflex V2 is able to combine a wide range of printing and finishing technologies inline to satisfy the requests of the market. The product integrates both UV and solvent-based flexo printing units inline.

Solvent-based flexo printing is mainly used in food packaging printing, in particular on plastic films, laminates or aluminum material for yogurt lids. Slovent-based flexo inks are cheaper than UV inks, but they need to be cured through specific hot air drying systems, which can also be produced on demand with the help of Omet.

The hot air drying modules, including high-performing blowers, are designed with different dimensions to better fit into the machine. It is also possible to combine UV curing and hot air drying systems on the same flexo unit.

Rotogravure is another printing technology using solvent-based inks that can improve the performance of the Omet Varyflex V2. Thanks to interchangeable groups, movement can occur everywhere in-between the flexo stations according to the job to be printed. Rotogravure is a cost-effective solution for solid printing, metallic inks and special varnish applications.

“We designed a few machines entirely prepared for solvent-based printing, and other machines with one solvent-based flexo or rotogravure unit inline for special color application, or exclusive projects featuring standard UV configuration with the addition of two rotogravure units–one in front and one at the end of the line,” explains Alfonso Melesi, Omet technical manager. “In this case, rotogravure technology is used to make compliant food packaging through solvent lamination, which doesn’t allow for ink migration.”

The Omet Varyflex V2  is available with web widths of 430 mm (16 7/8″), 530 mm (20 7/8″), 670 mm (26 3/8″), 850 mm (33 4/8″). The possibility exists to print with solvent-based flexo or rotogravure technology in the full compliance with international standards and Atex regulations in terms of explosion-proof equipment, which guarantees a safe working environment.
