Comexi F4 has been the leader in sales success and has also been the market benchmark since its launch in 2010. This flexo press is the most efficient solution for flexographic printing short-run with its 720 to 920 mm wide and a 600 mm maximum format. This press was the first to incorporate FLEXOEfficiency patented concepts, with ergonomics and accessibility as well as performance and robustness, which already characterize the whole range F2 and the newest Comexi F1.
Among other features, the Comexi F4 has pipe-less magnetic blades, patented by Comexi, allowing the printing unit to change in less than one minute. The press also has features with high added value and improved printing quality provided exclusively by Comexi. The machine also has other technical elements to minimize strip wear. In addition, Comexi F4 incorporates the Direct Direct Drive system to synchronize the central drum and the mandrels. This process is possible through encoders mounted directly on the axis, improving the reading accuracy and print register. The Comexi F4 has also been reinforced by a core anilox of 152 cm in diameter.
With the Comexi F4 maintenance is easier and more accessible. For example, the platform incorporates an easy-opening system to clean the central drum and it is possible to disassemble the drying screens from the side for cleaning. Furthermore, the threading material is easy and very accessible without the need of motorization or access stairs. It is also a user-friendly machine, for example, the control panel located strategically makes easier the printing process elements control.
Comexi F4 is able to print eight colors with different formats from 240 to 600 mm, widths up to 920 mm and a speed of 300 mpm.
