We have conceived, designed, and manufactured the Miniflex® 375 Bicolor, a flexo printer from our Miniflex® family, developed as an in-line solution specifically dedicated to the paper, non-woven, textile, and packaging industrial sectors. We structured this flexographic printing machine to work continuously and in-line with the moving substrate on unwinding flexible materials such as paper and cardboard.

To ensure accurate print results, we equipped the system with two distinct and independent printing units, a configuration that allows printing in two colors or, optionally, using a single color. From a production specification standpoint, our flexographic printer handles a fixed print width of 150 mm and a fixed print repeat of 600 mm, reaching an operating speed of 70 meters per minute. To keep the production process efficient and cost-effective, we adopted an inking system based on an Ultralox™ laser-engraved ceramic anilox roller, paired with a negative doctor blade constantly kept under pressure by a micro-cylinder. This equipment is primarily optimized for the use of water-based inks and is also compatible with solvent-based and UV inks. To support the process, we installed a drying system positioned between the two printing units, specifically designed to speed up the drying of the ink on the material.

Precision control of the entire system is entrusted to an independent electronic motorization for each unit. We developed a single electronic control and adjustment logic for the entire machine, governed by a single encoder dedicated to detecting the film’s running speed. The longitudinal register is managed electronically, while the transversal register is mechanical. To make operations increasingly easy, we designed the structure to slide manually along two guides, thereby facilitating the removal of the print roller, which is easily dismantled for cliché mounting. With the Miniflex® 375 Bicolor, a system with an approximate weight of 95 kg and compact dimensions of 1050 x 1100 x 885 mm, we deliver a rational technology, designed to accurately and reliably respond to industrial needs.
