100% inspection systems are becoming ever more important due to the high requirements in the labeling market. The consequence of the challenging requirements is that, in many areas, goods may not reach the ultimate consignee without a 100% check. This hurdle presents many printers with a major challenge. 

With SMARTSCAN, Erhardt+Leimer is offering an innovative solution that even goes beyond 100%. SMARTSCAN is the first 200% inspection system developed specially for narrow-web printing and finishing machines. The 200% inspection reliably detects print defects, damage to the material and missing labels. SMARTSCAN can be used not only for quality control in the labels market, but also for the checking of other printing applications, such as in packaging printing. The checking of unprinted, homogeneous materials, such as paper or film, is also possible.

SMARTSCAN – 200% print inspection

SMARTSCAN uses a unique, double image acquisition method for the inspection. Here, two image streams are acquired with a temporal offset – once with incident light and in parallel with transmitted light. Each of these image streams is compared with a dedicated reference image (golden template) and checked for defects.

The advantage is that, along with classic print defects, also material defects such as damage in the label or on the carrier, unremoved matrix, offset on the die cutting position, splice points or residue/insects on the rear of the label become visible. There is also special hole detection for films and foil.

One-click operation

With just one click of a button, SMARTSCAN is set up and immediately ready for inspection. All necessary parameters are set automatically, so there is no need for any further manual intervention. Thanks to this automated operating concept, which is unique in the market, the user hardly has to invest any time and can concentrate on his actual work.

Safety concept

A major plus for IT and system security: Even if there is a power failure, virus attacks, targeted manipulation or operational defects, the SMARTSCAN security concept means that there is no risk of losing data or that SMARTSCAN is no longer ready for operation. The operating system, the SMARTSCAN software and the system data are located on the writeprotected C partition of the SMARTSCAN PC and are thus safe. It is only possible to write to the D partition, which contains the system parameters, order data and roll reports. If necessary, the original state can be restored in seconds by restarting SMARTSCAN. The operating system does not need to be shut down for this. The security concept makes SMARTSCAN very robust and reliable.
