Europe: Two companies install printing press using offset technology

The Comexi Group, a provider of machinery solutions for the flexible packaging conversion industry, has recently reached new agreements to install its Comexi OFFSET CI8 printing press in two European companies from Austria and East Europe.

The Comexi OFFSET CI8 was found by the companies as an environmentally responsible printer while maintaining high standards of quality.

This is enabled by joining the advantages of both offset variable lengths and flexo central impression drum printing in one single press for flexible packaging and labels.

For the current flexible package printer excitement, Comexi Group is promoting to the market a central impression offset variable repeat printing technology, which looks set to transform flexible package printing into a more sustainable future.

The company has developed a press that replaces solvent inks by using EB curing technology, which allows the use of solventless and instantaneous cured inks without photoiniciators, fully compatible for its use in food packaging.

Its fast job changeover, high printing quality and pre-press low cost also characterize the Comexi OFFSET CI8.

These benefits are combined with a much cleaner printing process in comparison with flexo or rotogravure technologies.

The offset technology provides maximum flexibility in the production process, allowing short time-to-market, due to the fast in-house pre-press that allows preparing a new job while the press is still carrying out a previous one.

The printing cylinders are easy to exchange manually (automatic cylinder exchange is available as an optional) and all job parameters can be digitally stored and recalled. The pre-setting of mechanical adjustments like ink keys, form-rollers and printing cylinders are automatic.

In addition, the offset technology uses lithographic plates, with much less costs compared with photopolymers or engraved cylinders used in traditional flexo and rotogravure technologies.

The cost reduction at this part of the process allows changing the design and language, adding new logos or making promotional campaigns without additional printing costs.

It also allows reducing minimum print runs and printing film in stock.

The Comexi OFFSET CI8 press use servo drive technology, allowing fast production, reduced press downtime and start-up waste.

The machine prints in up to seven colors, plus white or lacquer, with a web width of 900 mm or 1100 mm, at a maximum speed of 300m/min.
