摘要
为了研究水性油墨喷墨印刷过程中喷印工艺参数对涂布铜版纸印品质量的影响,分析印品质量评价指标与喷印工艺参数间的正负相关性。印刷时,先改变喷墨印刷中喷头电压、点火频率、脉冲宽度的关键工艺参数,再测量印品实地密度、色差、明度和光泽度4个质量评价指标,定性分析各工艺参数对印品质量评价指标的正负相关性,最后采用统计学分析方法分析喷印工艺参数对印品质量的影响,并采用偏最小二乘回归法建立相应的回归模型。研究结果表明:脉冲宽度对涂布纸印品的实地密度、色差、光泽度、明度的影响较大,点火频率和喷头电压在一定范围内对涂布纸印品的实地密度、色差、光泽度、明度的影响较小,故在涂布纸水性油墨喷墨印刷过程中,通过合理地控制喷印工艺的关键参数可提高印品质量;偏最小二乘回归预测模型对印品的色差和明度具有较好的预测能力。
In order to study the in?uence of spray printing process parameters on the printing quality of coated copperplate paper in waterborne ink-jet printing process, the positive and negative correlation between the specific quality evaluation index and the spray printing process parameters was analyzed. By changing the key process parameters of nozzle voltage, ignition frequency and pulse width in inkjet printing, and measuring the four key quality indicators of printed matter, namely, field density, color difference, brightness and gloss, the positive and negative correlation of each process parameter to the speci?c quality indicators of printed matter was qualitatively analyzed. Then, statistical analysis method was used to study the influence of printing process parameters on printing effect. Finally, partial least square regression method was used to establish the corresponding regression model. The results showed that the pulse width had a great in?uence on the ?eld density, color difference, glossiness and brightness of coated paper prints, and the ignition frequency and voltage had a relatively small in?uence on the ?eld density, color difference, printing glossiness and brightness of coated paper prints in a certain range. Therefore, in the process of water-based ink-jet printing of coated paper, the quality of the printed matter can be improved by reasonably controlling the key parameters of the printing process. The partial least square regression prediction model had a good prediction ability for the color difference and lightness of the printed matter.
