VARIABLE DROP VOLUME CONTINUOUS LIQUID JET PRINTING |
| 摘要 |
A liquid jet includes a fundamental period of jet break off. A print period is defined as N times the fundamental period of jet break off where N is an integer greater than 1. Input image data is provided having M levels per input image pixel including a non-print level where M is an integer and 2<M@N+1. A charging device waveform, independent of the input image data, repeats during print periods and includes print and non-print drop voltage states. A drop formation device waveform, having a period equal to the print period, is selected in response to the input image data to form from the jet print drops having a volume corresponding to an input image pixel level. The devices are synchronized to produce a print drop charge to mass ratio and a non-print drop charge to mass ratio on drops breaking off from the jet. |
