Quality control in sheetfed

As well as camera-based quality control systems for sheetfed print, Switzerland-based FAG Graphic Systems is now also offering densitometric inline colour measurement.

The new FAG Spectra Scan is based on the measuring technology of the usual handheld densitometer available. The light source, colour and pol-filter as well as the sensor are all integrated into the compact measuring head. The device is mounted on a traverse over the sheet conveyor and is said to be easy to position. As required, several measuring heads can be used. FAG, which says it is "almost synonymous with
proofing", also has products for ink fount control and blanket washing, as well as software lines.
