热转移印刷中油墨转移渗透理论的研究

Study on Ink Transfer Osmotic Effect in Thermal Transfer Printing

主要研究了印刷压力、印刷时间、孔渗比等相关印刷参数与油墨渗透深度的关系。在经典油墨渗透模型的基础上,通过引入孔渗比的油墨渗透模型,克服了纸张毛细管半径不易测量的问题,为热转移印刷中油墨渗透深度的研究提供了更为有效的方法。通过分析各印刷参数与油墨渗透深度的关系,可为实际操作中提高热转移印刷质量起到一定的指导作用。

This paper studied the relationship between ink penetration depth and printing parameters such as printing pressure,printing time,porosity and permeability ratio.Based on the theory of classic ink penetration model,a novel ink penetration model was proposed by introducing the porosity and permeability ratio to provide a more effective way to study ink penetration depth.The problem of paper capillary radius can be neglected by using this model.The relationship between printing parameter and ink penetration depth can be calculated which may play an important role to guide the actual operation to improve the quality of thermal transfer printing.
