中文摘要:
      目的 制备一种高线数(200线以上)的微透镜阵列防伪膜,改变国内印刷包装行业对微透镜阵列防伪膜的制备停留在200线以下的圆点微透镜阵列防伪膜的现状。方法 采用卷到卷、圆压圆的制备工艺,以聚碳酸酯为原料,采用激光微刻技术制备模具,压印温度设置为139 ℃,转移速度设置为5 m/min。结果 制得一种正六角形半球状微透镜阵列防伪膜,微透镜边长为32 μm,栅距为48 μm,膜厚为121 μm,根据微透镜阵列结构参数关系折算后光栅线数为529线。结论 实现了高线数、高填充系数的微透镜阵列防伪膜的制备,提供了一种工艺简单、适于批量生产的微透镜阵列防伪膜制备方法。
英文摘要:
      The work aims to fabricate a micro-lens array anti-counterfeiting film with a high number of lines (more than 200 lines) to break through the situation that the micro-lens array anti-counterfeiting film fabricated in the domestic printing and packaging industry is the dot domestic printing and packaging industry with less than 200 lines. With polycarbonate as raw material, the laser micro-engraving technology was used to fabricate the mold through the roll-to-roll and rotary fabrication process. The embossing temperature was 139 °C and the speed was 5 m/min. A positive hexagonal hemispherical micro-lens array structure anti-counterfeiting film was fabricated. The side length of the micro-lens was 32 μm, the pitch was 48 μm and the film thickness was 121 μm. According to the relationship between the micro-lens array structure parameters, the converted grating lines were 529 lines. The fabrication of micro-lens array anti-counterfeiting film with a high number of lines and high filling factor is achieved. A method for the fabrication of micro-lens array anti-counterfeit film is provided, which is simple and suitable for mass production.
