• Big companies from Europe have trusted this sustainable high quality printing concept to respond their current customers’ demands
• The Comexi printing press, which incorporates offset technology to the central drum, is unique in the market
The Comexi Group, a leading company specialist in machinery solutions for the flexible packaging conversion industry, has recently reached new agreements to install its Comexi OFFSET CI8 printing press. Specifically, two main European companies from Austria and East Europe have trusted the Comexi’s offset technology to boost their machinery fleet so that respond stringent customers’ demands.
All these converters seek maximum quality, sustainability and increase productivity in their products. Consequently, the Comexi OFFSET CI8 becomes the suitable solution to strengthen their positioning as environmentally responsible printers 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.
Market demands as opportunity for market leaders
It is not new that flexible packaging has been facing the rising costs of materials and price pressures while run lengths have been decreasing. Within this scenario, operating costs and specifically changeover times and waste are key factors to take into account when deciding the best printing solution.
Brand owners are increasingly demanding to add value to their packs; highest quality, fast delivery and competitive prices are perhaps never ending requests. Those demands are challenging the capabilities of the converters with traditional technologies. It is an opportunity for those converters to introduce an innovative technology that easily solves those requirements and simplifies operational processes.
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. Worldwide announced by Comexi Group in 2012, the Comexi OFFSET CI8 press is the market leader for sustainable short and medium runs.
The benefits of combining fast job changeover with EB curing technology
Comexi Group 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. All 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 very 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.
Another point to be highlighted is the considerable savings for the companies due to the fast and keen in-house plate making. Offset technology is characterized by the use of 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 7-colors, plus white or lacquer, with a web width of 900 mm or 1100 mm, at a maximum speed of 300m/min.
