拉丝镭射转移接装纸凹版印刷油墨配方的优化研究

Optimization of ink formulation for gravure printing on wire drawing laser transfer paper

为制备具有优异印刷适性的酯溶专色油墨,探究了稀释剂含量、酯溶金红含量和酯溶中黄含量对黄珠光专色油墨物理性能和印刷适性的影响。首先,通过单因素实验和响应面分析法对黄珠光专色凹印油墨的配方进行了系统优化,通过调整稀释剂、酯溶金红和酯溶中黄在接装纸凹印专色油墨中的配比,成功制备黄珠光专色凹印油墨;其次,对专色油墨的物理性能进行检测,并研究了不同配比的专色凹印油墨对印刷适性的影响;最后,采用凹版印刷的方式进行印刷效果研究。结果表明,稀释剂、酯溶金红和酯溶中黄含量均对油墨的印刷质量有一定的影响,当稀释剂、酯溶金红和酯溶中黄的质量比为18∶0.55∶1.95时,油墨的色差仅为1.29,制备的油墨具有优异的流变性能、流动度、印刷光泽度和印刷效果.

In order to prepare ester⁃soluble spot colour ink with excellent printability,the influences of diluent content,ester⁃soluble gold red content and ester⁃soluble middle yellow content on the physical properties and printability of yellow pearl spot colour ink are explored.Firstly,the formulation of yellow pearl spot colour gravure ink is systematically optimized through single factor experiment and response surface analysis.By adjusting the proportions of diluent,ester⁃soluble gold red and ester⁃soluble middle yellow in spot⁃colour gravure printing ink,a yellow pearl spot colour gravure printing ink is successfully prepared.Secondly,the physical properties of spot colour ink are tested,and the influences of different proportions on printability of spot colour gravure ink are studied.Finally,the printing effect is studied via gravure printing routine.Results show that the printing quality of ink is affected by the content of diluent,ester⁃soluble gold red and ester⁃soluble middle yellow each.The ink prepared has a colour difference of 1.29 only,and excellent rheological properties,fluidity,printing gloss and printing effect when the mass ratio of diluent,ester⁃soluble gold red and ester⁃soluble middle yellow is 18∶0.55∶1.95.
