Problems solved by technology

Another disadvantage of three-dimensional moiré is that some people's eyes will feel uncomfortable when they see it (because of the different visual distance and focal point, compared with the front), it is better to watch it at a longer distance
[0006] Three-dimensional moiré has many limitations and challenges in printing. At present, the moiré that is often seen is mainly monochrome. If you want to print color moiré, there will be a problem of misregistration, which will often cause serious color difference in the entire batch of printed products. Generally, it is best to print spot color (special color) plus four colors together for moiré.
[0007] This shows that the above-mentioned existing three-dimensional printing method obviously still has inconvenience and defects in method and use, and needs to be further improved urgently.
In order to solve the above-mentioned problems, the relevant manufacturers have tried their best to find a solution, but no suitable design has been developed for a long time, and there is no suitable structure and method for general products and methods to solve the above-mentioned problems. This is obviously a problem that relevant industry players are eager to solve

Embodiment 1

[0093] Utilize an acrylic sheet with hemispherical lenses on one side, 120 cm long and 80 cm wide, with a hemispherical lens density of 100,000 lenses per square inch. Coat the surface modifying layer 2 on it, which is to increase the adsorption and adsorption speed of the ink, and then use an industrial-grade digital inkjet printing machine exposed to ultraviolet rays to print a printing layer 3 with precise patterns. The precision of the pattern is every 1 Inch 1000 dots (equivalent to 1 million dots per square inch), then, further add a hard coating of one deck transparent resin above the pattern as ink protective layer 4, which is acrylic resin or epoxy resin, so A three-dimensional printed decorative panel is formed. The printing resolution of this example is 10 times of the lens density, and the obtained decorative board has excellent three-dimensional printing effect and pattern resolution.

[0094] Place 20 36-watt LEDs from Optoelectronics on both sides of the three-...

Embodiment 2

[0096] Utilize an acrylic sheet with hemispherical lenses, 120 cm long and 80 cm wide, with a hemispherical lens density of 40,000 lenses per square inch. Surface modifying layer 2 is coated thereon, as in the printing precision and printing process of embodiment one, the printing layer 3 of imprinting precision pattern, pattern precision is 1000 dots per inch (equivalent to 1 million dots per square inch) , Then, further add a hard coating layer of transparent resin on the top of the pattern as ink protection layer 4, which is acrylic resin or epoxy resin, thus forming a three-dimensional printed decorative plate. In this example, the printing resolution is 25 times of the lens density, and the obtained decorative board has an excellent three-dimensional printing effect, but the pattern resolution is obviously reduced.

Embodiment 3

[0098] Utilize an acrylic sheet with hemispherical lenses, 120 cm long and 80 cm wide, with a hemispherical lens density of 100,000 lenses per square inch. Surface modifying layer 2 is coated thereon, such as the printing precision and printing process of embodiment one, the printing layer 3 of imprinting precision pattern, the pattern precision is every 1 inch 500 dots (equivalent to 250,000 dots per square inch), Then, further add a layer of transparent resin hard coat on the pattern as ink protective layer 4, which is acrylic resin or epoxy resin, thus forming a three-dimensional printed decorative plate. The printing resolution of this example is 2.5 times of the lens density, and the resulting decorative plate does not have a three-dimensional printing effect.

Abstract

The invention relates to a three-dimensional printing method and a decorative plate and a lamp box manufactured through the method. The three-dimensional printing method includes the steps that printing is carried out on a sheet material with a concave-convex surface by means of printing ink capable of being hardened through ultraviolet rays or electron beams, so that the concave-convex appearance of the surface of the sheet after printing is maintained, the printing resolution is 5 times to 20 times of concave-convex density, and the decorative plate with a visual three-dimensional field depth effect is generated. When the sheet material with the concave-convex surface is a transparent lens material, the high-contrast decorative plate or the lamp box can be formed due to the combination of the transparent lens material and a reflective sheet material or a backlight source.

Description

technical field [0001] The invention relates to a three-dimensional printing method, which can be used for printing on various materials, and produces a visual effect of three-dimensional depth of field as the unevenness of the material surface changes. This technology can be used for three-dimensional printing on various objects, from Sheets are used for surface decoration of various furniture or commodities. When the three-dimensional printing is on a transparent lens sheet, it can be combined with a light source to become a light box. Background technique [0002] Stereoscopic imaging technology can be divided into two categories: (a) the stereoscopic effect can be observed directly with both eyes; (b) the stereoscopic effect can only be observed by wearing auxiliary tools (for example: wearing special glasses). Among them, the first type of stereoscopic imaging technology includes: parallax barrier stereo method (Parallax Barrier), also known as black line stereo method...
