Barcode Verification

Thermal printing and 'print & apply' systems are notorious for being inconsistent in print quality over a period of time. Ambient temperature changes, material substrate property variations, printer ribbon variation, machine running temperatures, adhesive build-up...these can all contribute to a degradation in print quality and a barcodes ability to be successfully decoded.

1D analogue linear barcodes do not have the same built-in error correction capability of a 2D Data Matrix code and as a result have a very low threshold between successful reading and failure.

The only answer is to control and monitor the print process inline with verification.

With the arrival of 'shelf ready' packaging it is now more important than ever that suppliers control barcode print quality. Without barcode verification you cannot be 100% of print quality across the width of the barcode and therefore your customers' ability to decode with different hardware in a different environment.

Ensuring a consistent even image across the width of the field of view is essential if you are to have a successful barcode verification solution. Siemens NER are a leader in LED machine vision lighting and a Distributor of the NER range V-viz can help and advise on the correct lighting for your application.

Siemens Acuity CiMatrix have been pioneering verification for 25 years and their expertise and understanding of machine vision ensures that their verification products are second to none in terms of qualitative measures, performance and image acquisition to process times. As their Technology Partner with years of recommending, integrating and supporting verification solutions V-viz is well regarded in this field across many industries.
