根据胶印机出墨量数字控制要求及其工艺原理，设计了数控墨斗机械结构部分，并对胶印机墨斗进行了三维实体造型的设计，验证了墨斗设计的合理性。以单片机ATMEL-AT89S52作为控制元件，以步进电动机作为执行控制对象，设计了总体控制电路方案，制作出了系统的硬件控制系统，并根据调墨原理对控制系统编制了控制软件。

According to the requirements of numerical control of ink flow and its technology theorem, the mechanical structure of numerical control ink fountain and the three-dimensional solid model for offset press was designed. The rationality of ink fountain design was verified. Overall control circuit project were designed, the hardware control system was made using ATMEL-AT89S52 singlechip as control component, and using step motor as the implementation object. According to the principle of ink adjusting, control software for the control system was programmed.
