CIJ Printing

CIJ Printing in the technical glossary of LEIBINGER Inkjet and Numbering Machines.

CIJ is the short form for Continuous inkjet. This kind of printing is primarly used for coding and marking of products.

In this technology a pump directs fluid from a reservoir tank to one or more small nozzles which eject a continuous stream of drops at high frequency. The drops pass through a set of electrodes which impart a charge onto each drop. The charged drops then pass a deflection plate which uses an field to deflect the drops which should be printed. Undeflected drops will be collected and returned for re-use. The high drop ejection frequency of CIJ gives a capability for very high speed printing and is suitable for applications such as date coding on beverage cans, cable or packaging.
