Abstract：Aiming at the problems of big data to process and transmission rate mismatch in gray micro-droplet jetting technology，after

the analyse of the characteristics and control method of grayscale micro-droplet jetting technology，a gary micro-droplet jetting control

system base on ARM and FPGA architecture and dual port RAM ping-pang operating technology was presented. The timing simulation of

FPGA internal module was established based on Modelsim software. The gray levels and edages swatooth were tested on the gray microdroplet

jetting experiment platform.The results indicate that the system can achieve the maximum width of 280 mm and 8 grayscale microdroplet

jetting and the printed image edges are sharp and clear with no obvious swatooth.

Key words：continuous grayscale；micro-droplet jetting；control system
