Embodiment Construction

[0033] In order to fully understand the technical content of the present invention, the technical solutions of the present invention will be further introduced and illustrated below in conjunction with specific examples, but not limited thereto.

[0034] Such as Figure 1 to Figure 7 It is a drawing of an embodiment of the present invention.

[0035] In this embodiment, letters A and B are used as micro-text elements, and a true-color lena image is used as an image to be processed for specific description.

[0036] Set the lena image to CMYK mode, and then perform color separation to get such as figure 1 The four color separation sheets of C, M, Y, and K, with the letter A as the micro-text element, through the micro-structure halftone processing technology and the micro-text array processing technology for the four color separations of C, M, Y, K image processing to obtain four color separations C1, M1, Y1, and K1 with micro-text element A, and recombining the four color se...

Abstract

The invention relates to a processing method of micro lens true-color 3D printing images. According to the processing method of the micro lens true-color 3D printing images, through combination between a microstructural halftone processing technology and a micro image-text array processing technology, multi-tone true-color images are made, and not only can the obtained 3D images have a repeated 3Darray element effect which can be achieved in the prior art, but also generated array elements can be different in size and color; more importantly, the true-color 3D images capable of presenting abundant tones are obtained.

Description

technical field [0001] The invention relates to the technical field of printing image processing, and more specifically refers to a method for processing microlens true-color 3D printing images. Background technique [0002] In recent years, the demand for microstructured optical films in the packaging market has been increasing, and the production of dynamic high-depth 3D images through microstructured optical films has become an object of research and development in the packaging market. The 3D image production of microstructured optical film is a moiré magnification technology realized by combining microlens array (Microlens array, MLA) and micropattern array (Micropattern array, MPA). Moiré magnification refers to the phenomenon that can occur when an array of identical micropatterns is viewed from an array of microlenses having roughly the same periodic dimension, ie in the form of magnification or rotation of the micropatterns. The fundamentals of the Moiré amplificat...
