印刷廠家的靜電噴墨印刷技術

印刷廠家靜電噴墨印刷的實現是通過圖像信號控制的噴墨系統和承印物之間的電場改變噴嘴錶面張力的平衡,在靜電場吸引力的作用下,使墨滴從噴中噴射出去,到達承印物錶面形成圖文。

其基本原理是在噴嘴與承印物之間形成一個強度合適的靜電場,並通過向噴嘴發送一個基於圖文信號控制的脈沖來產生墨滴,脈沖控制墨滴的噴出和沿指定路徑通過電場到達承印物,形成圖文。

該技術主要利用“秦勒”效應由靜電噴墨技術產生的墨滴尺寸遠遠比噴嘴的尺寸要小,因此具有高分辨力的特點。

一般來說,噴墨印刷具有300~1500dpi的分辨能力,階調數為多值(但有限),而且容易實現噴頭的多嘴化,成像速度非常快,但需要較高的工作電壓。

大多數噴墨成像都採用水基油墨,呈色劑以染料為主,最終影像的形成取決於油墨與承印物的相互作用。
