First of all, micro-nano optical texture is a kind of physical color rendering, which is achieved by the refraction of nanoscale microstructures and light. Compared with traditional pigments, inks and other forms of color development, structural colors are more environmentally friendly and more variable. At the same time, through the design of surface microstructure, micro-nano optical texture can realize the visual effect of three-dimensional dynamic color change in appearance, which is not available in traditional pigment printing, especially the dynamic visual effect, which subverts the traditional color.
Micro/nano texture structure production process: graphic design - structure design - template making - nanoimprint - enhanced protection - composite or transfer - post-press process - finished product output. Usually product design follows three principles: applicability principle, manufacturability principle, and cost-effective principle, these micro-nano optical texture materials can be well matched.
Principle of applicability.
Micro-nano optical texture has strong applicability in terms of color expression effect and material adaptability. **In terms of color, the optical color of micro-nano texture can achieve a rich design effect. The micro-nano optical texture processing plate-making equipment has high precision, and will be designed in a structured way, which can be made into a high-resolution texture structure, which can diversify the saturation and visual effect of the structural color. At the same time, micro-nano texture materials have strong adaptability and can be combined with various types of materials such as metal, glass, ceramics, cloth, paper, and plates, which greatly broadens the variability of texture applications.
Manufacturability principle.
Optical texture can be applied to the surface of objects of different materials by transferring, compositing, and hot stamping processes. Among them, metastasis is divided into global metastasis and local metastasis. Integral transfer refers to the overall transfer of the designed micro-nano structure information film layer to the surface of the product materialThe local transfer adopts printing and coating methods, and the micro-nano structural color is locally transferred to the surface of the material through the composite, curing and peeling of the release micro-nano structure material, and the local transfer usually needs to be positioned.
The principle of cost performance.
Micro-nano optical texture can be combined with the printing process to achieve a variety of first-class effects, and it is a very good choice to do surface decoration. For example, in the practical application of the car interior decoration industry, carbon fiber texture is often used to replace leather finish, which ensures the overall texture while greatly reducing the cost and is cost-effective.
Both traditional printing and micro-nano optics have their own characteristics and advantages, which can be presented separately or combined for application. Compared with traditional printing, micro-nano optical texture is a kind of technological innovation and change, and it is also a supplement to traditional printing technology.
With the development of various micro-nano optical textures, their applications can involve makeup, daily use, automobiles, home appliances, 3C, etc., and in the near future, we will see micro-nano optical textures everywhere.
