Embodiment 1

[0030] 1) According to such as figure 1 The pattern to be printed is shown as a film image. The film image is composed of a printed dot array. The density and size of the dots in the printed dot array are changed based on the corresponding relationship with different parts and color levels of the pattern to be printed so that the pattern to be printed can be produced. Layering, where the gray level of the weakest gray area A of the pattern to be printed is 15%, and the silk screen film is 20 lines.

[0031] 2) Make a screen according to the film image, and the mesh specification of the screen is 80T.

[0032] Use the method commonly used in this field to make the screen, but you need to pay attention to: ① When stretching the net, if there is a radian on the panel, reserve the elasticity of the screen mesh according to the size of the radian; ② Coat the screen with photosensitive glue, It is required that the thickness must be uniform; ③ bake the photosensitive plastic screen...

Embodiment 2

[0036] 1) According to such as figure 1 The pattern to be printed is shown as a film image. The film image is composed of a printed dot array. The density and size of the dots in the printed dot array are changed based on the corresponding relationship with different parts and color levels of the pattern to be printed so that the pattern to be printed can be produced. Layering, wherein the grayscale of the weakest grayscale area A of the pattern to be printed is 15%, and the silk screen film is 30 lines.

[0037] 2) Make a screen according to the film image, and the mesh specification of the screen is 80T.

[0038] 3) Use the screen plate to print the pattern to be printed on the substrate by the method of screen printing commonly used in this field. The partial effect picture is as follows image 3 shown (with figure 2 display at the same scale).

Embodiment 3

[0040] 1) According to such as figure 1 The pattern to be printed is shown as a film image. The film image is composed of a printed dot array. The density and size of the dots in the printed dot array are changed based on the corresponding relationship with different parts and color levels of the pattern to be printed so that the pattern to be printed can be produced. Layering, where the gray level of the weakest gray area A of the pattern to be printed is 15%, and the silk screen film is 25 lines.

[0041] 2) Make a screen according to the film image, and the mesh specification of the screen is 80T.

[0042] 3) Use the screen plate to print the pattern to be printed on the substrate by the method of screen printing commonly used in this field. The partial effect picture is as follows Figure 4 shown.

[0043]The decorative board produced by the screen printing method of the present invention shows different layers and different senses of virtuality and reality through monoc...

Abstract

The invention discloses a screen printing method and decorative panels produced through the same. The screen printing method includes the following steps of 1), producing a film pattern according to a pattern to be printed; 2), producing a screen board according to the film pattern; and 3), printing the pattern to be printed on an object to be printed through the screen board in the screen printing method; wherein the film pattern is formed by a printing screen dot array, and the density and the size of the screen dots of the printing screen dot array change according to the corresponding relationship with different portions and color gradation of the pattern to be printed. The screen printing method utilizes single color printing to achieve diverse showing forms of the pattern to be printed as well, so that the effect is more vivid and natural. Moreover, compared with the prior art, the ink using amount is reduced in a screen printing area of the same size due to the voids of the dot array, so that the production cost is saved.

Description

technical field [0001] The invention relates to the field of decorative panel printing, in particular to a screen printing method and a decorative panel produced by the method. Background technique [0002] With the development of the home appliance industry, consumers have put forward higher requirements on the appearance of home appliances, and setting beautiful patterns on home appliances has become a way to improve their appearance. [0003] At present, most of the patterns of air-conditioning injection molding panels are mainly screen printing, but the screen printing technology can only print one color at a time, that is, single-color ordinary screen printing. During printing, through the extrusion of the scraper, the ink is transferred to the substrate through the mesh of the graphic part, forming the same graphic as the original. Due to the single color and pattern expression, this silk screen printing process only has the visual effect of plane graphics, so that it...
