Chosen for consistency and print quality, the compact and lightweight Allen Coding NGT2+ systems, which replaced obsolete coders, are installed on separate packaging lines where they operate on a 24/7 basis.

The  coders form part of an intermediate step in CooperVision’s stringent packaging process. They are printing barcodes on to 12 x 19mm labels which are then applied to silver foil blister strips.

Alistair Harkins, production engineer at CooperVision, says: “We used Allen Coding printers before so were happy to choose their NGT2+ systems as replacements for older, obsolete units. Our main priority was consistency of operation and print quality. If the barcode isn’t clearly legible for any reason, we lose traceability which has a negative impact on safety.

Each NGT2+ is handling up to 1200 labels per hour, with one label for three blister packs. As part of CooperVision’s quality control procedures, the blister packs are then checked by a barcode reader.

Alistair Harkins, production engineer at CooperVision, says: “As expected, the NGT2+ printers have proved easy to operate, with quick change consumables, and been good in terms of reliability, which has helped minimise downtime and maintain production efficiencies. The service and support provided by Allen Coding has been truly excellent, with any enquiries dealt with quickly and efficiently.

“As a result, I would definitely recommend Allen Coding and its marking and coding equipment to other medical device manufacturers,” he concludes.

As well as barcodes, Allen Coding’s NGT2+ is capable of printing fixed and variable data, graphics, use-by dates, real time and batch codes.

For maximum flexibility, it can be easily switched between intermittent and continuous mode. In continuous operation, the NGT2+ offers a maximum print area of 53 x 1000mm and print speed of 35m/min. It has a print resolution of 12 dots/mm or 300dpi.

The NGT2+ can be operated via PC or a:touch 2 touch screen. It works with a wide range of software solutions, including a:control, which is a printer operation platform software, specially developed by Allen Coding to supervise user and permission management. It can configure up to ten printers in a network. The company’s a:design2 is simple and intuitive software for print image design.
