Summary of Processing Processes of Laser Film 真空喷镀 Vacuum spraying 完成压镭射图文后，如果要实现金属效果就需要在压好的镭射图文上喷镀一层金属箔，主要采用真空镀铝机将不同的金属丝通过强电流在真空容器中雾化，覆盖在压好的镭射膜上。喷镀环节可以镀铝、镀铬、镀镍、镀铜、镀铁等，可以镀出哑光素面、亮光镜面等效果，真空喷镀效果由所采用的金属材料而定。 After completing the laser drawing and text, if we want to achieve the metal effect, we need to spray a layer of metal foil on the pressed laser drawing and text. The vacuum aluminizing machine is mainly used to atomize different metal wires through strong current in the vacuum container and cover the pressed laser film. Spraying links can be aluminized, chromium plated, nickel plated, copper plated, iron plated, can be plated matte, bright mirror and other effects, the effect of vacuum spraying depends on the metal materials used. 真空喷镀的工艺操作难度很大，以真空镀铝为例，受电压、电流、真空度、材料纯净度等因素影响，镀铝过程可能会产生铝变色。飞溅、掉铝、黑点、斑点、起泡等质量缺陷，会影响最终的镭射膜质量，容易造成转移不良和大量掉铝现象。 Vacuum spraying process is very difficult to operate. Taking vacuum aluminium plating as an example, aluminum discoloration may occur due to voltage, current, vacuum, material purity and other factors. The quality defects such as spattering, aluminium dropping, black spots, spots and foaming will affect the quality of the final laser film, which will easily lead to poor transfer and a large number of aluminium dropping. 经过真空喷镀工艺后，为保证后加工顺利进行，必须对金属箔进行表面处理，以改善印刷适性。处理方式主要有两种：涂布清漆（涂料）和电晕处理，可根据金属箔表面性质的不同选择适当的处理方式。 After vacuum spraying process, in order to ensure the smooth processing, surface treatment of metal foil must be carried out to improve the printing suitability. There are two main methods of treatment: varnish coating and corona treatment. Appropriate treatment methods can be selected according to the different surface properties of metal foil. 除了上述普通镭射压膜技术外，激光全息防伪定位镭射模压技术也是比较新的高科技压膜技术，与普通镭射膜生产工艺不同，在压定位镭射膜的时候，需要在制版前就计算好全息防伪镭射印刷的位置，将防伪图案植入镭射模压版中特定的位置，然后进行激光定位模压，这样在转移激光全息定位镭射膜时，就能把防伪镭射图案转移到印品表面的相同位置。 In addition to the above-mentioned common laser film pressing technology, laser holographic anti-counterfeiting positioning laser film pressing technology is also a relatively new high-tech film pressing technology. Different from the ordinary laser film production technology, when pressing and positioning laser film, it is necessary to calculate the position of holographic anti-counterfeiting laser printing before plate making, insert the anti-counterfeiting pattern into the specific position of laser plate pressing, and then carry out laser positioning module. In this way, the anti-counterfeiting laser pattern can be transferred to the same position on the printed surface when laser hologram is transferred to locate the laser film. kongzhigui.75ix.cn baohuqid.75ix.cn baohuqi.75ix.cn zhenkongdaib.75ix.cn zhenkongdaic.75ix.cn tanceqi.75ix.cn |
