Research In Controller Of High-performance Ink-jet Plotter

Ink-jet plotter is a kind of important computer peripheral, with the development of electronic technology has greatly improved the promotion of the printing technology, enables high-speed, high-precision ink-jet printing possible.Based on the analysis of the working principle of the ink-jet plotter, and the combination of a particular model hot-bubble inkjet head, analyze the ink-jet head driving method, the impact to the drop by drive the timing, and precision control methods to the drop. Secondly, proposed FPGA-based modular design implement many ink-jet head work at the same time. For the data-processing requirements when the time of high-speed, high-precision print, propose an FPGA-based high-speed ping-pong cache methods, and ultimately implement the print speed o 8 m2/h and the precision of 1200 DPI, these performance indicators has basically reached the mainstream of foreign products.
