文档介绍：the numeral prints and the numeral printing ink type Discussed digital printer and the numeral printing ink type along with printing digitization step quickening, the numeral prints cTP and so on the new technology to be like a raging fire. Already es prints the irreversible mainstream development technology now. The digital printing printability also has the obvious difference with traditional printing. To the printing equipment printing material, the printing technology set the new request. In order to achieve the good print quality and the high velocity production. The digital printing material, in particular the numeral printing ink research and the development appears importantly. After several years development, the numeral printing ink technology Zhen will be later day mature. But the numeral printing ink high price still was restricts the digital printing development the bottleneck The digital printing image formation principle needs to discuss the numeral printing ink, must talk about the digital printer inevitably, because the different factory promotes the digital printer image formation principle is different, to uses the numeral printing ink position performance, the character request to be also different. At present uses the digital ElSiJ equipment image formation principle may divide into six big kinds ?? 1. electrons according to?? 20 called the static electrici
