Embodiment 1

[0039] Embodiment one: a kind of method of digital laser plane color painting, comprises the following steps:

[0040] (1) See attached Figures 1 to 3 As shown, a multi-layer film structure with an information layer, the information layer in the film structure can be black resin, or a resin impregnated with C, M, Y (or R, G, B) tricolor dyes ( figure 1 ), or the light-varying graphic information of the relief phase structure with a reflective layer ( figure 2 ), and finally made to coat the release layer, information layer, and adhesive layer from the inside to the outside of the substrate layer, thereby forming an attached image 3 The multi-layer film structure shown is the required thermal transfer film;

[0041] (2) The multi-layer film structure is closely attached to a hard material, and the pulsed laser beam is shaped into a uniform square or circular spot through the optical path to irradiate the covered film, so that the film is instantly heated at the position o...

Embodiment 2

[0043] Embodiment two: a kind of method of digital laser plane painting, comprises the following steps:

[0044] (1) prepare a kind of multi-layer thin film structure with information layer, in this thin film structure, information layer can be black resin, or be infiltrated with C, M, Y (or R, G, B) tricolor dye For the optically variable graphic information of resin or relief phase structure, the release layer, information layer, and adhesive layer are respectively coated on the substrate layer from the inside to the outside, thus forming a multi-layer film structure;

[0045] (2) The multi-layer thin film structure is closely attached to a hard material, and the pulsed laser beam is shaped into a uniform square or circular spot through the optical path to irradiate the film, so that the instantaneous heating temperature of the film at the position of the spot area reaches 120-150 degrees, so that the information layer in the film is separated from the base layer and adsorbe...

Embodiment 3

[0047] Embodiment three: a kind of method of digital laser roller painting, comprises the following steps:

[0048] (1) prepare a kind of multi-layer thin film structure with information layer, in this thin film structure, information layer can be black resin, or be infiltrated with C, M, Y (or R, G, B) tricolor dye Optically variable graphic information of resin or embossed phase structure, the final effect is made by coating the release layer, information layer, and adhesive layer from the inside to the outside of the substrate layer, thereby forming a multi-layer film structure;

[0049] (2) The multi-layer thin film structure is closely attached to a flexible material, and the pulsed laser beam is shaped into a uniform square or circular spot through the optical path to irradiate the film, so that the instantaneous heating temperature of the film at the position of the spot area reaches 120-150 degrees, so that the information layer in the film is separated from the base l...

Abstract

The invention discloses a method for laser digital colored drawing, which comprises: (1) a heat transfer printing film including an information layer is attached to the surface of the material going through the colored drawing; (2) the relative position of an optical head and the material going through the colored drawing is adjusted so as to ensure that the irradiating position of the laser beam to target the position of drawing pixels, (3) the laser beam is ensured to perform the instant heating to causes the information layer of the heat transfer printing film on the surface of the material to be melted and dropped off so as to be attached on the material going through the colored drawing; (4) according to position data of the predetermined image pixels, the step (2) and the step (3) are executed once again until the drawing of the information layer is completed; (5) the heat transfer printing film including another information layer is replaced, the step (1) and the step (4) are repeated until the drawing of all of the information layers is completed, namely the required laser digital colored drawing is realized. The method has the advantages of flexible control, high image precision, good colored drawing effect, more particularly, the capability of drawing the optical variable images with metal texture, etc., and is suitable for the application of digital laser colored drawing in the industries of digital printing, anti-counterfeiting and textile.

Description

technical field [0001] The invention relates to a digitally controlled painting method, which is suitable for painting various color graphics or optically variable graphics with grating microstructures on various hard and flexible materials. Background technique [0002] Color painting technology is widely used in people's daily life, including printing various advertisements, printed products, packaging materials, or clothing in daily life, even as small as buttons and key chains. At present, the more mature methods are: digital inkjet painting, laser sublimation color printer, etc. [0003] Utilize ink-jet printer to realize digital color painting, but its processing speed is relatively slow, and cost is very high, especially when processing large-scale color painting, above-mentioned defect appears more prominent. [0004] The working process of a laser color printer is a cyclical action process through seven steps of charging, exposing, developing, image transfer, fixin...
