US 2002/0118251 A1 · MULTI-COLOR LEVEL INKJET HEAD CHIP STRUCTURE

Abstract

The present invention is a multi-color level inkjet head chip structure, at least including a pre-mixing space. The pre-mixing space communicates with different ink storage spaces through a plurality of providing elements, then the volume of different colored inks is controlled by means of the ink providing elements to be injected into the pre-mixing space. The desired color level ink is created in the pre-mixing space in advance. Finally, the desired color level pre-mixed ink is jected onto the recording media (such as paper or other similar material) through an inkjet printing driver at the pre-mixing space. Therefore, the desired color level can be produced by only one inkjet printing at any printing area, which will be extremely beneficial for increasing the speed of inkjet printing.

A multi-colors level inkjet head chip structure, utilized to eject a plurality of different color inks onto the surface of recording media, at least comprising a inkjet printing unit constructed by the following elements:

a pre-mixing space, having an ink nozzle, enabling inks to pass through and to be ejected onto the surface of said recording media;
a plurality of ink providing elements, communicating a plurality of different color inks with said pre-mixing space;
a plurality of ink providing drivers, installed in said ink providing elements, utilized to inject different color inks into said pre-mixing space to mix according to the respective preset ink volume so as to get an expected color level ink;
and
an inkjet printing driver, installed in said pre-mixing space, utilized to eject said expected color level ink onto the surface of said recording media.
