Abstract

In continuous stream ink jet printers it is conventional practice to catch unused ink droplets in a gutter and recirculate the ink back to the head for re-use. With continued recirculation the volatile products in the ink tend to evaporate in the gutter during machine operation, ultimately requiring either the addition of volatile products to the ink, or the replacement of the ink supply due to its increase in density.
