银墨内衬纸复合工艺参数研究

目的确定凹印纸铝复合的印刷速度和压力,为凹印银墨印刷生产烟标内衬纸提供基础生产数据。方法以幅宽650mm凹印复合机为基础,进行内衬纸原纸和银墨的复合印刷,并在预实验过程中采集数据,并通过插值拟合法对实验数据进行处理,确定最佳印刷速度和印刷压力。结果根据油墨转移量的实验结果可以得出,在1000 r/min,3 MPa条件下得到较好的油墨转移量;对上机实验所得的实验结果进行插值拟合,插值并进行十阶拟合计算后得出,在1050 r/min,2.79 MPa时,内衬纸表面银墨油墨转移量效果最佳。结论初步验证了凹印印刷银墨进行烟标内衬纸的可行性,为烟标内衬纸复合提供了一种新的复合思路和方法。

Composite Process Parameters of Silver Ink Lined Paper

The work aims to determine the printing speed and printing pressure of gravure paper aluminum composite to provide basic production data for the production of cigarette liner paper for gravure silk ink printing. The composite printing of liner paper and silver ink was carried out with the 650 mm gravure composite machine, and the data were collected during the pre-experiment process. The experimental data were processed by interpolation fitting method to determine the optimal printing speed and printing pressure. According to the experimental results of ink transfer amount, there was a good ink transfer amount at 1000 r/min and 3 MPa. The interpolation fitting was carried out based on the experimental results obtained by the machine experiment. After the interpolation and the 10th order fitting calculation, the effect of the amount of silver ink transfer on the surface of the liner paper was the best at 1050 r/min and 2.79 MPa. The feasibility of gravure printing silver ink for cigarette liner paper is preliminarily verified, which provides a new composite idea and method for cigarette liner paper composite.
