Abstract
Method and Apparatus for Reducing Ink Foaming in a Continuous Inkjet Printer The invention provides a method of and apparatus for reducing foam formation in the returned ink in a continuous inkjet printer. The returned ink is subjected to deceleration and is reduced in pressure, preferably by being directed into a sub-chamber which reverses the direction of flow and provides an elevated edge over which the ink overflows. The de-aeration facility is preferably incorporated in an ink service module.
