Abstract

The work aims to achieve the color effect of dynamic images based on lenticular lens arrays by rasterizing micro-patterns with wavelengths comparable to visible light. First, a CTP plate was used to achieve the output of micro pattern arrays, which were then matched with the lenticular lens array layer, ultimately achieving basic amplification effect and dynamic amplification effect; Next, by periodic patterning the micro patterns with period comparable to visible light, the micro patterns could have a structural color effect through the interaction between nano structures and visible light, achieving a special color effect that did not rely on traditional ink coloring. Then, the micro pattern layers with characters "宽窄" and "2024" were matched with lenticular lens arrays to form the dynamic color effect pattern. The characters were compressed along the x-axis and y-axis directions, allowing for arbitrary modification of character spacing in the corresponding y-axis and x-axis directions, respectively, thus achieving a complete color magnified image. This method enhances the structural color effect of micro patterns through the interaction between nano structures and visible light, while matching with lens arrays to form dynamic color effect patterns. It can provide an optical control and reproduction method for the green printing, environmentally friendly, and personalized products, realizing the application of dynamic color changing thin film products.
