Method and apparatus for obtaining homogeneous ink for inkjet devices

摘要

In order to obtain homogeneous ink for CIJ printers, an inkjet is divided into individual equally large ink droplets, at least part of the ink droplets is provided with an electric charge, and the ink droplets are guided by a deflection device. The ink droplets which are deflected by a predefined amount are collected by a homogenization droplet catcher and are used for printing.

1. A method for obtaining homogeneous ink for inkjet devices, comprising:
dividing an ink jet into individual equally large ink droplets; providing at least some of the ink droplets with an electric charge; guiding the ink droplets through a deflection device; collecting a portion of the ink droplets which is deflected by a predefined amount by a homogenization droplet catcher, wherein each ink droplet of the collected portion has a fixed charge-to-mass ratio corresponding to the predefined amount of deflection; and utilizing the ink droplets collected by the homogenization droplet catcher in a printing operation.
