The printing system Flexo Offline SA910/01 is an independent self-powered printing station that allows to carry out the whole printing cycle off-line, from corona treatment to the ink drying, as well as to accomplish the material cut. Flexible, versatile and easy to be used, this system is the ideal solution to print on aluminium foil for blister packaging in the pharmaceutical sector.
This printing system is composed by an unwinding-rewinding unit to unwind the aluminium reels, having max. diameter of 350 mm and max. height of 300 mm, and to rewind them at the end of the production cycle up to 100 m-min. The rewinding machine is complete with electronic control system of tensioning both for unwinding and for rewinding. Moreover, the machine is equipped with a web edging guide device in order to ensure the perfectly aligned rewinding of printed reels.
The corona treatment unit is fitted on the unwinding-rewinding machine to prepare the material for printing. The treatment system is equipped with an extractor fan for ozone expulsion.
After the treatment unit, we find a printing machine Miniflex FUV512/300. This printer is suitable for printing using UV inks and has a max. printing width of 300 mm. Being a gearless flexo printing machine, that means with double motorization (one for the printing roller and one for the engraved ceramic anilox roller), and being equipped with in-line sleeve changing system, this unit can print several printing repeats just by few quick operations. Indeed, it can fit sleeves having development ranging from 350 to 700 mm. Moreover, it is equipped with a multi-function software giving the possibility to work in “continuous mode” (in this case the printing repeat is given by the development of the printing roller) and in “Variant mode” (printing repeat settable from control panel). The combination of the sleeve change system and of the multi-function software with “Variant mode” allows achieving many different printing repeats, thus reducing the operations to carry out and avoiding useless and expensive working intervals. Besides, thanks to the innovative software and to the precision of mechanical devices, it is possible to achieve centred prints with a high register precision.
The inking system by laser engraved ceramic anilox roller and by closed chamber ensures to transfer the right ink quantity to the printing clichés and, as a consequence, to obtain a high printing quality.
After that, the prints are polymerized by means of a UV lamp.
Lastly, before the final reel rewinding, the material reel is cut longitudinally by means of a double blade cutting system.
Since the FLEXO OFF-LINE SA910/01 can achieve a wide range of different printing repeats and can carry out the complete production cycle, it is the machine ideal for printing also small and medium quantities and for production requiring modifying often the repeats and the printing logos.
