Abstract

An ink/air separator for an ink jet printer has one or more platesover which an ink/air mixture can spread. Preferably there is more than one plate, and the mixture overflows from one plate to the next. Preferably adjacent plates are spaced so that as the mixture passes between two plates it contacts the surface above it as well as the surface below it. The plates may be separated by a gap of 10 mm or less, e.g. a gap of 2 mm to 5 mm, where they overlap Preferably some or all of the plate surfaces contacted by the mixture are roughened. Interaction between the ink/air mixture and the plate surface tends to slow the flow of very small air bubbles and encourage them to accumulate and/or merge, so that they separate from the ink more quickly than individual small bubbles. The ink/air separator may be connected in the path of unused ink returned from the gutterof a continuous ink jet printer to an ink tank, or may be placed inside the ink tank
