凹印水性油墨在烟包印制中的应用研究

针对水性油墨在烟包凹印生产过程中出现的暗影和实地不实等问题,改善其印刷适性,以实现规模化印刷生产。首先,调整油墨配比,采用IGT对水性油墨和溶剂型油墨进行印刷适性实验,验证其能否满足产品质量要求;其次,通过调整版滚筒网穴深度、镀铬层厚度、油墨黏度、刮刀、p H值等,对烟包条盒进行了试生产,并统计分析了各批次工序的废品率及投入产出率。结果表明:水性油墨较溶剂型油墨废品率略高,投入产出率略低,水性油墨印制的烟包能够符合烟厂要求。因此,为了满足环保的需要,凹印水性油墨可以用于规模化烟包印制生产,值得推广。

Research on the Applying of Water-based Ink in Gravure Printing of Cigarette

This topic for water-based ink in production in cigarette packet gravure shadow field problem such as false, improves its optimum printing to realize large-scale printing production. First it adjusts the ink ratio, by using IGT test of printing eligibility of water-based ink and solvent-based inks, verifies whether meeting the requirements of product quality. Then it adjusts the Roller mesh point hole depth, chrome layer thickness, ink viscosity, scraper, pH, trial production of the strip box, and statistical analysis of each batch process the rejection rate and the rate of input-output. Results show: the waste rate of water-based ink is slightly higher than the solvent based ink. The input-output ratio is slightly lower, but the water-based ink can meet the requirements of cigarette factory. Therefore, water-based gravure ink can be used for large-scale production of printed cigarette package for the environment,worthy of promotion.
