图像处理光变图像光栅转移复制 image processing optically variable device grating groove transfer

摘要

制作具有光变图像(OVD)光栅条纹的大面积全息原版,是激光图像无油墨印刷的核心技术之一。提出一种通过在金属镍母版表面高频感应加热和快速加压的工艺方法,在压敏材料上实现了微米级精细光栅条纹的高效率快速转移,其列阵式的转移复制方式实现了大面积光变图像的制作。研制了用于光变图像光栅条纹大面积复制的新型智能化组版系统,并对此智能化组版系统的结构和工作原理作了阐述。同时,对影响光栅条纹转移复制的几个方面作出了分析。对复制前后的光变图像光栅进行的测试表明,转移后光栅的衍射效率可以高于母光栅。研制的这一新型智能化组版系统可转移复制的组版面积达1000 mm×1600 mm。

Abstract

The technology to make a large area master with the grating of optically variable device (OVD) is role in holographic image embossing. A computerized recombining system is designed for transferring the grating of the optically variable device onto the surface of the pressure-sensitive materials with high efficiency. The induced heating device is used to heat the nickel shim quickly so that the temperature on the surface of the shim can be adjusted precisely. The system can produce a large area OVD plate transferred it with the method of array. The properties of the OVD′s on the nickel plates before and after transferring process are measured and analyzed. The principle of the recombining system is explained. Some aspects to affect the quality of transferring are given. The results show that the diffraction efficiency of transferred OVD can be higher than that of original shim. The size of recombining OVD plate can be achieved up to 1000 mm×1600 mm.
