Slitting rewinders are at the end of the label production process and they are responsible for removing waste before the final product is shipped to the customer. Traditionally, rewinders are equipped with stroboscopes, missing label detectors, flag and splice sensors aimed at detecting common label production defects. These devices are difficult to adjust and rely on the attentive operator to be in working order.

The printing of variable data during the finishing process is increasingly popular for pharmaceutical and security labels. The ALIS-Jet group controller automates the multiple ink-jet head configuration and monitoring. The optional camera unit verifies the printed variable data and detects ink-jet malfunction and smear. The screen of the Alis-Jet helps the operator monitor the printing and perform maintenance procedures on the heads from the front of the machine. Integration with rewinder electronics automates tasks like starting a new numbering sequence and printing additional repair sequences. The first label of the sequence is automatically placed on the rewind shaft.

Modern label production starts with product design on the computer screen. Once approved, the design data is sent in electronic format to the printer. After many processing steps, a set of printing plates and die-cutting tools is prepared. On the printing press, these plates are capable of producing millions of labels. It is very important before and during production to verify that the printed label is identical with the customer approved design.
The Offline Digital Reference Inspection system was designed to automate the costly, time consuming and error prone visual verification of labels. The ODRI system uses a DIN A1, A2 or A3 scanner to read one print repeat of the product and automatically compares it with the PDF data used to make the plates for the product. The system automatically marks suspicious spots and highlights the differences for the operator. Inspection results are summarized in industry standard production reports for quality assurance documentation.
