基于FPGA的宽幅单PASS多喷头驱动研究

针对多PASS印刷模式输出速度低和当前单PASS模式成本高的缺点,系统采用由多个小型喷头组成喷头阵列构成单PASS印刷模式,该方法不仅可以避免多PASS模式与当前单PASS模式的缺点,而且更加灵活。利用FPGA高速、灵活的优势实现了对大量印刷数据的缓存与异步读写操作,在FPGA内部实现了多喷头的并行驱动。实验结果表明,该系统可以实现高速、持续地宽幅面印刷输出,证明了设计的可行性与正确性。

Research of Multi-jet Drive with Wide Format and Single-PASS Based on FPGA

For multi-PASS printing mode which has a low output speed and the high cost of current single-PASS model,a new printing method,which uses components of multiple small nozzles to form single-PASS printing mode was proposed.This method could not only avoid the disadvantages of multi-PASS mode and the current single-PASS scheme,it was more flexible.FPGA with high-speed and flexible advantages was used to achieve a large number of printing data caching and asynchronous reading and writing operations.The multi-nozzle parallel driving was achieved within the FPGA.Experimental results show that the design can achieve high-speed and wide format printing output,and proves the feasibility and correction.
