Description

Technical Field

[0001] The present invention relates to the field of printing technology, and particularly to printed matter with a stereoscopic visual effect and a printing method thereof. Background Art

[0002] In traditional printing technology, most printed matter presents a flat visual effect. Although it can convey information through colors and patterns, it lacks a three-dimensional sense and a sense of spatial hierarchy, and it is difficult to meet the growing high requirements of consumers for visual experience.

[0003] Some existing printed matter with a three-dimensional effect, such as raised patterns formed by embossing printing, although it can bring a certain tactile and visual three-dimensional sense, this three-dimensional sense is relatively single, and it requires special printing equipment and processes, with high costs. There is also printed matter that achieves a three-dimensional effect through a grating plate. The fitting accuracy between the grating plate and the printed image requires extremely high precision, and the thickness and material of the grating plate will affect the overall effect. In the production process, problems such as image ghosting and blurring are likely to occur, resulting in a poor stereoscopic visual effect, and at the same time, it also limits the application scenarios of the printed matter.

[0004] Therefore, those skilled in the art have provided printed matter with a stereoscopic visual effect and a printing method thereof to solve the problems raised in the above background art. Summary of the Invention

Through innovative structural design and printing methods, a rich and vivid stereoscopic visual effect is achieved, and the application fields of the printed matter are broadened.

Detailed implementation manners

[0020] The present invention will be further described in detail below in conjunction with the drawings and specific implementation manners. The embodiments of the present invention are given for purposes of illustration and description, and are not exhaustive or limit the present invention to the disclosed form. Many modifications and variations are obvious to those of ordinary skill in the art. The embodiments are selected and described to better illustrate the principles and practical applications of the present invention, and enable those of ordinary skill in the art to understand the present invention and design various embodiments with various modifications suitable for specific purposes. Embodiment

[0021] Please refer to Figures 1-2 , in this embodiment, a printed matter with a stereoscopic visual effect and its printing method are provided, including A printed matter with a stereoscopic visual effect, including a substrate layer, on which a stereoscopic pattern printing layer is provided. The stereoscopic pattern printing layer is composed of multiple sub-pattern layers with different depths, and each sub-pattern layer corresponds to a different visual depth. The sub-pattern layer is printed with semi-transparent ink, and there is a difference in transparency between adjacent sub-pattern layers; the printed matter further includes a light refraction layer, which is arranged above the stereoscopic pattern printing layer. The light refraction layer is composed of multiple micro-structure units with different refraction angles. The micro-structure units correspond to the patterns of the sub-pattern layers and can refract the light reflected by different sub-pattern layers, thereby enhancing the stereoscopic visual effect. The number of the sub-pattern layers is 3-8. By reasonably setting the number of sub-pattern layers, while ensuring the stereoscopic visual effect, it is possible to avoid the complexity of the printing process and the increase in cost caused by too many layers; the transparency difference between adjacent sub-pattern layers is 10%-30%. Such a transparency difference can make obvious visual depth differences formed after the superposition of each sub-pattern layer, enhancing the stereoscopic sense of hierarchy. The shapes of the microstructural units include triangular prism shape, pyramid shape or hemispherical shape. These microstructural units with different shapes can refract light in different ways according to actual needs to achieve the best stereoscopic visual effect. The height of the microstructural units is 0.1 - 0.5 mm. This height range can not only ensure sufficient refraction of light but also not affect the overall flatness and aesthetics of the printed matter due to excessive height. The substrate layer is made of paper, plastic film or metal foil. The appropriate substrate material can be selected according to different application scenarios and requirements of the printed matter to improve the applicability of the printed matter. The present invention also provides a printing method for a printed matter with a stereoscopic visual effect, which specifically includes the following steps: S1: Design a stereoscopic pattern. Using computer graphics design software, according to the required stereoscopic visual effect, decompose the stereoscopic pattern into multiple sub-patterns with different visual depths, and each sub-pattern corresponds to a sub-pattern layer. S2: Prepare translucent ink. According to the transparency required for each sub-pattern layer, formulate translucent inks with different transparencies. S3: Print the sub-pattern layers. Using screen printing or inkjet printing methods, print each sub-pattern layer on the substrate layer in the order of visual depth from deep to shallow, and perform drying treatment after each printing. S4: Prepare a light refraction layer. By means of die pressing or laser engraving, form microstructural units with different refraction angles on a transparent material to obtain a light refraction layer. S5: Lamination. Laminate the light refraction layer with the substrate layer printed with the stereoscopic pattern printing layer to make the microstructural units accurately correspond to the patterns of the sub-pattern layers, and complete the production of the printed matter with a stereoscopic visual effect.

From the sub-pattern layer with the deepest visual depth to the shallowest one, their transparencies are 30%, 40%, 50%, 60%, and 70% in sequence. The sub-pattern layers use translucent ink and are printed on the substrate layer in sequence by screen printing. After printing, it is dried in an environment at 60 °C for 15 minutes. The light refraction layer uses a transparent plastic film, and triangular prism-shaped microstructural units are formed on the film by die pressing.

Finally, the light refraction layer and the substrate layer printed with the stereoscopic pattern printing layer are compounded by hot pressing. The hot pressing temperature is 80 °C and the pressure is 0.5 MPa to obtain a printed matter with a stereoscopic visual effect. After testing, when observing this printed matter from different angles, it can present an obvious stereoscopic visual effect, and the three-dimensional sense and spatial hierarchy of the pattern are relatively strong.

Then, using the method of screen printing or inkjet printing, each sub-pattern layer is printed on the substrate layer in the order of visual depth from deep to shallow, and drying treatment is carried out after each printing; the temperature of the drying treatment is 50-70°C, and the drying time is 10-20 minutes. Then, by means of die pressing or laser engraving, microstructural units with different refraction angles are formed on the transparent material to obtain a light refraction layer. Then, the light refraction layer is laminated with the substrate layer printed with the three-dimensional pattern printing layer, and the light refraction layer and the substrate layer are laminated by means of hot pressing lamination or adhesive bonding, so that the microstructural units correspond accurately to the patterns of the sub-pattern layers, and the production of the printed matter with a three-dimensional visual effect is completed.
