Firstly a deep analysis and research of the moiré pattern through Geometric analysis was provided in this article, in conjunction with the mechanism of its production as well as its equations in printing. After that , through integrating with the practice, the main factors that affects the moiré pattern was discovered, such as the fit angles , frequency, shape and microstructure of the original pictures. Finally, this article discussed the design principle of the moiré security pattern, and the different patterns about it were concluded with impression drawings. Such patterns for security mainly included zoom behavior, composing and coding. 目 录 莫尔条纹防伪印刷技术探讨相关范文 |
