    • Disclosed herein is a method for electrostatic printing, wherein the method comprises (a) providing an ink composition comprising particles comprising a resin, wherein the ink composition contains less than 0.3 mg of charge director per g of solids in the ink composition; (b) passing the ink composition between a first electrode and a developer roller, wherein sufficient potential is applied between the developer roller and the electrode such that the resin particles are charged and adhere to the developer roller; (c) transferring at least some of the particles from the developer roller to a photoimaging plate to form an image on the photoimaging plate; and (d) transferring the image from the photoimaging plate to a print medium. Also disclosed here is an apparatus for carrying out the method, and a print medium printed using the method.
    • 本文公开了一种静电印刷方法,其中所述方法包括(a)提供包含树脂的颗粒的油墨组合物,其中所述油墨组合物在所述油墨组合物中含有少于0.3mg的电荷指示剂/ g固体; (b)使墨水组合物在第一电极和显影辊之间通过,其中在显影辊和电极之间施加足够的电势,使得树脂颗粒被充电并粘附到显影辊上; (c)将至少一些颗粒从显影辊转印到光成像板上以在光成像板上形成图像; 和(d)将图像从光成像板传送到打印介质。 这里还公开了一种用于执行该方法的装置和使用该方法打印的打印介质。
