Apparatus for printing multiple drop sizes and fabrication thereof |
| abstract |
The present invention is a print head with nozzles of differing radii, which allows multiple drop sizes in the same print head. This can be used to weight drop sizes to achieve multi-level printing, allowing higher print quality at the same resolution. Print heads with six rows of nozzles can use the CC'MM'YK color system to attain high print quality. This system requires three differing optical densities: full optical density for yellow and black, 2/3 optical density for the most significant bits of cyan and magenta, and 1/3 optical density for the least significant bits of cyan and magenta. To achieve the various optical densities, the drop volume can be different for the various color components. A manufacturing method for print heads uses microelectronic lithographic processes on a silicon wafer, with ink channels and individual nozzles etched through the wafer. Many thousands of nozzles can be fabricated simultaneously in one print head. The radius of individual ink nozzles is determined by the mask patterns used during various lithographic processes, and nozzles with differing radii can be simultaneously fabricated without requiring extra manufacturing steps. |
