可食性喷墨油墨为水性油墨，绿色环保，其原料全部符合食品卫生标准，可以用喷墨印刷的方式直接在食品、药品或产品的包装表面印刷，具有色彩鲜艳、无毒、无污染的特点。采用在油墨中添加不同含量的染料、树脂及表面活性剂的方法，改变油墨的黏度和表面张力，探讨不同性能的可食性喷墨油墨对印刷品质量的影响。采用CCD图像检测分析系统，对印刷品的线条质量、实地填充质量及圆点质量进行评价和分析；用密度计测量印品的色密度并进行颜色评价。结果表明，可食性喷墨油墨的黏度和表面张力影响印刷品的质量，通过调整树脂及表面活性剂用量，可以获得适于喷墨印刷的可食性喷墨油墨。

Edible inks for ink-jet printing is water-based and environmental friendly and all of its raw materials reach the food sanitation standards. It can be directly printed on the surface of food, medicine and packaging in the non-contact ink-jet printing way. The ink samples are prepared by different amount of dye, resin and surface active agent. The viscosity and surface tension of the samples are tested, and the influence of the ink with different performance on the quality of presswork is discussed. The products printed by this ink are innocuous, pollution free and bright in colour. Line quality, field filling quality and dot quality of printing are evaluated and analyzed through a CCD camera-based industrial image analysis system. The result shows that the viscosity and surface tension of edible ink-jet ink have an effect on the quality of printing. Edible ink- jet ink suitable for printing is available by changing the amount of resin and surface active agent.
