ABSTRACT:
An ink jet head for ejecting drops of ink in an ink jet printing system is designed for easy disassembly for cleaning and can readily be made in different sizes including one capable of ejecting relatively large volume drops of heavily pigmented and relatively viscous ink as may be used for printing outdoor billboards or other large scale graphics. The head also includes a means for reducing the size of or entirely eliminating any blob of ink which may form over the ejection port at low actuating frequencies, thereby making the velocity and other characteristics of the ejected drops more uniform over the full range of operating frequencies.
