摘要
在食品包装中,结合光栅材料光学性质和半色调图像加网技术,对光栅印刷莫尔条纹生成规律和防伪应用研究具有重要意义。采用理论计算的方法对莫尔条纹形成及分布特征进行分析,并通过实验对分析和计算进行验证。针对食品包装光栅印刷的实际情况,根据莫尔条纹形成规律,选择适宜的光栅印刷加网角度和网屏/光栅线数比,可以有效消除或减弱莫尔条纹的影响。
Combined with grating in food packaging materials,optical properties and the halftone image and network technology,studied the anti-counterfeiting grating moire fringe of printing forming rules.Explored the new technology of food packaging,and adopt the method of theoretical calculation of moire fringe formation and distribution characteristics.And the analysis and calculation are verified by experiments.According to the actual situation of food packaging grating printing,and the laws of the moire fringe formation,the results showes that choosing suitable grating and screen printing and network Angle/grating line ratio,can effectively eliminate or weaken the influence of the moire fringe.
