Metapack supply Digiline Blister for in-line and off-line printing and inspection of Alu-foil blister.
Digiline Blister machine has been conceived and realised for the late stage customization of filled and sealed blisters, i.e. by printing on the aluminium surface of each single blister with the industry proven DOD UV technology. The machine can be used as a stand-alone unit or in line, feeding the cartoner or being fed by the blister machine.
The printing process relies on the industry-proven DOD UV digital printing system, widely used in many sectors for digital high-quality printing. Digiline blister machine can be equipped with one or more heads, each one providing one single colour print and with print width of 36, 72 or 144 mm.
The final curing is provided by the “SMARTCURE” unit, a UV lamp which activates the ink polymerisation (curing) in a fraction of a second, i.e. immediately compared to the travel speed.
After being printed, the blisters travel under the Inspection camera which can provide two main types of inspections:
- OCR/OCV of variable data and ID control of barcodes (1D and 2D)
- Full print quality inspection (option)
Because the print is on an aluminium surface, the camera system works with a linear camera associated to an illumination system which assures for no reflections are generated by the aluminium, for guaranteeing a correct image acquisition of the printed layout.
This solution assures for optimal performances with minimum space requirements and, more important, with a fixed mechanical set-up which is independent from the blister dimensions.
