    Abstract: An enhanced optical interference pattern, such as a diffraction grating, is incorporated into a photodefinable surface by shining three or more beams of coherent light from a single source at a photodefinable surface, such as a photosensitive emulsion/photoresist covered glass or an ablatable substrate and mapping the diffraction grating pattern to the photodefinable surface. Mapping of the optical interference pattern is created by interference of three or more light beams, such as laser light or other light sources producing a suitable spectrum of light. The mapped photodefinable surface can be used to create embossing shims. The embossing shim can then be used to emboss film or paper. The embossed film/paper can be metalized and laminated onto a substrate to create a product that has shifting patterns at a variety of viewing angles when exposed to white light.

    Abstract translation: 增强的光学干涉图案，例如衍射光栅，通过在可光限定的表面例如感光乳剂/光致抗蚀剂覆盖的玻璃或可烧蚀的基底上照射来自单个源的三个或更多个相干光束而被并入可光限定的表面，以及 将衍射光栅图案映射到可光限定表面。 光学干涉图案的映射是由三个或更多个光束的干涉产生的，例如产生合适光谱的激光或其他光源。 映射的光可定义表面可用于创建压花垫片。 然后可以将压花垫片用于压花膜或纸。 压花膜/纸可以被金属化并层压到基底上以产生当暴露于白光时具有各种视角的移动图案的产品。

    Abstract: A variety of deep structured decorative patterns originate with mechanical relief or etching A deeply patterned or textured etching or relief is incorporated into a thin film embossing shim to simulate the look of the deep pattern or texture when used to emboss thin film or mateπal A transparent mold of the relief surface (such as brushed metal, engine-turned patterns, and textured glass) is formed using UV curable liquid and a transparent substrate The relief copy in the transparent mold or overlay is mapped onto a photoresist surface or plate by shining or expanding one or more laser beams through the transparent mold The thin film embossing shim is then used with conventional embossing equipment to form thin film embossings The embossed thin films can then be metalized and laminated onto substrate to create shifting patterns that reflect at a variety of viewing angles when exposed to white light.
