Laser printing device and method for color dynamic graphics

Abstract

The invention discloses a laser printing device and method of a color dynamic image, wherein the laser printing device of a color dynamic image comprises: an optical system and a recording material, and the recording material includes a refraction layer formed by a plurality of microspheres or microlenses, formed The light-shielding layer on the focal plane of multiple microspheres or microlenses; the optical system includes a laser and a graphic generation device, the laser light emitted by the laser is processed by the image generation device, and then irradiated on the recording material, and the laser light irradiated on the recording material is refracted The layer is focused on the light-shielding layer, and when the energy of the focused laser is greater than the evaporation threshold of the light-shielding layer, a focal point is correspondingly formed on the light-shielding layer. Through the deflection of the incident angle of the laser beam by the laser printing device of the color dynamic image of the present invention, laser focus points at different positions are formed on the focal plane of the recording material, and thermal deposition of different pigments is realized. Repeat the deflection of the incident angle to form laser printing of multi-channel color graphics, and finally form the reproduction of color multi-channel dynamic images.

Description

technical field [0001] The invention relates to the technical field of laser printing, in particular to a laser printing device for color dynamic images and a corresponding printing method. Background technique [0002] Dynamic images and three-dimensional imaging can be realized through microlens array imaging technology. Specifically, a layer of microlens array is first attached to the laser recording material, and then a projection imaging system generates an image above the microlens array, and the microlens array images the recording material under the lower focal plane of each microlens. The recorded information is reproduced in space by the microlens array. With different observation positions, the reproduced image has a dynamic effect. [0003] The existing laser marking technology can form ablated images or characters on the surface of materials through the photothermal effect of the laser focus point on various substrates. This way the image or question is flat a...
