阅读说明：本技术 一种数码打印方法、数码打印机及存储介质 (Digital printing method, digital printer and storage medium ) 是由 李其相 林炜 于 2020-05-22 设计创作，主要内容包括：本发明涉及数码打印技术领域,特别是涉及一种数码打印方法、数码打印机及存储介质。本发明实施例提供的数码打印方法、打印机及存储介质可以根据获取的图像数据控制用于喷涂润湿液和彩墨的打印装置在承印物上多次交替喷印润湿液和彩墨,从而使承印物上打印出的图像中的润湿液层和彩墨层交替分布。因此,彩墨层能与相邻的润湿液层充分接触并充分反应,从而增加了彩墨层与润湿液层的结合强度。因此,本发明实施例提供的数码打印方法、打印机及存储介质打印出的图案色牢度高,在洗涤和使用过程中不易损坏。(The present invention relates to the field of digital printing technologies, and in particular, to a digital printing method, a digital printer, and a storage medium. The digital printing method, the printer and the storage medium provided by the embodiment of the invention can control the printing device for spraying the wetting liquid and the color ink to alternately spray the wetting liquid and the color ink on the printing stock for multiple times according to the acquired image data, so that the wetting liquid layers and the color ink layers in the image printed on the printing stock are alternately distributed. Therefore, the color ink layer can be sufficiently contacted and sufficiently reacted with the adjacent wetting liquid layer, thereby increasing the bonding strength of the color ink layer and the wetting liquid layer. Therefore, the patterns printed by the digital printing method, the printer and the storage medium provided by the embodiment of the invention have high color fastness and are not easy to damage in the washing and using processes.)
