Colour register systems specialist QI Press Controls has added automated fountain solution control to its IDS colour density system.
The standard IDS offering scans and analyses the printed web and compares the image to a prepress version, controlling and correcting colours via the ink fountains. Now analysis algorithms have been expanded to include water.
The company says dampening supply control can fluctuate at times, such as when the press is warming up. Judgements about water control which an operator may make when viewing the printed product – perhaps through a magnifying glass – are now automated by the IDS system.
Functions operate within a cycle of about 100 prints and can be implemented in existing IDS/IQM systems.
