同一般印刷油墨组成一样,水性油墨球探体通常也有着色剂,连结料,辅助剂等成分组成。着色剂是水性油墨的呈色物质,给油墨一特定颜色。在柔印中为使印迹色彩艳丽,其着色剂一般选用化学稳定性好,着色力高的颜料;连结料由水,树脂,胺类化合物及其他有机溶剂组成。树脂为水性油墨中最重要的成分,通常使用水溶性丙烯酸树脂,连结料成分直接影响油墨的附着功能,干燥速度,防粘脏性能等,同时也影响油墨光泽及传墨性,胺类化合物主要维持水性油墨的碱性PH值,使丙烯酸树脂提供更好的印刷效果,水或其它有机溶剂主要是溶解树脂,调节油墨的粘度及干燥速度;辅助剂主要包括有:消泡剂,阻滞剂,稳定剂,冲淡剂等几种。由于水性油墨是一种皂组合物,使用中易产生气泡,因此要加入硅油作为消泡剂,来抑制和消除气泡,同时提高油墨的传递性能。阻滞剂用于抑制水性油墨的干燥速度,防止油墨在网纹辊上干固,减少糊版。稳定剂可以调节油墨PH值,也可作稀释剂来降低油墨的粘度。冲淡剂是用来减淡水性油墨的颜色,也可作为一种亮光剂,提高水性油墨的亮度。另外水性油墨中还要加入一些蜡质来增加其耐磨性。
