    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.
