Error Management Systems

Barcode reader

Barcode reader

This technology has been available for many years to ensure mistakes are eliminated in the processing of printed matter. Gathering machines, saddle stichers and automatic sewing machines can be retro-fitted with optical readers which will check sequence of signatures/sheets, print quality and folding accuracy. The technology can be connected to automatic reject systems and stop circuits where appropriate, to ensure that mistakes are eliminated. In this case there is a simple learning system after which the machine will detect errors. Barcode systems can be used for any of the above applications and to verify covers to books for on demand digital printing. Blank sheet detectors are available to retrofit all types of folders reading the top and underside of the sheets automatically stopping the feeder when a blank sheet is detected. This device is essential for security printing and the pharmaceutical industry.
