The web inspection system scans the entire width of the paper web, acquiring at full speed high-resolution images on the full surface of each page and comparing them to a related “golden sample” in order to carry out many different kinds of quality and contend check. Printing quality and content errors are identifi ed at an early stage, thereby triggering immediate action and reducing both, downtimes and the amount of wasted paper.


The system can be integrated as simplex and duplex color versions for the following devices and printers:

IPI – Intelligent Print Inspection

IPI stands for Intelligent Print Inspection and enables a new way of performing print inspection. In general, the concept of ‘digital print image inspection’ refers to the comparison of a printed sample to a pre-defined template.

In traditional print inspection, the operator creates the template for image matching (Golden Template). A number of features to be checked are selected on a printed page that has been found to be “good”.

IPI opens another way to create the template for image matching: Instead of having the template set by the operator, the IPI system uses the raw print data directly sent from the printer controller to the inkjet print heads. This means IPI dynamically reads this data and generates a digital image on-the-fly without affecting the printer. This dynamically generated image serves as a template for the system to compare with the print sample.
