数码无版印花技术的发展

Advances in Digital Stencil-Less Printing

无版印花技术可以大大地简化印花过程,为目前国内外印花技术的发展方向之一。20世纪80～90年代以来,数码喷射印花技术进入了蓬勃发展时期,同时又出现了数码静电印花技术。数码喷射印花技术具有快速反应、即时生产供应,印制效果好、对环保有利等特点。但存在生产速率太慢和成本太高的缺点,影响其在生产上的大量推广应用。数码静电印花技术通过目前样机试验,已可发现其具有喷射印花技术的特点,且可较大程度地改善后者的二个主要缺点,估计今后很有发展前途。

Digital ink jet printing is characterized by rapid response, excellent printed effect and environmental friendly adventages. But its drawbacks are low production speed and high cost. Digital static printing technology possesses the same charateristics of ink-jet printing but minimizes its drawbacks. Although only the sample machine of digital static printing has passed the trial experiment at present, yet it has good prospects in future.
