Embodiment 1
[0029] Example 1: Production of on-hook panels for air conditioners
[0030] (1) Select a substrate 2 made of polymethyl methacrylate (PMMA) with a thickness of 1.5mm, and plan a pattern area for forming a three-dimensional image on the substrate 2 according to the pattern shape to be formed. The substrate 2 is sent into a semi-automatic screen printing machine, and a dot layer 3 composed of several regularly distributed colored dots is printed on the back of the substrate 2 by screen printing. The size of the colored dots in the dot layer 3 is determined by The center gradually increases toward the edge, and the angle of the screen line of the colored dots is 45°. After the printing is completed, it is sent to an electric heating dryer and dried for 20 minutes at a temperature of 50°C, and the printing of the dot layer 3 is completed;
[0031] (2) The printed substrate 2 of the colored dot layer 3 is sent to a semi-automatic screen printing machine, using a 200-mesh screen, a...
Embodiment 2
[0034] Example 2: Production of air-conditioning cabinet panels
[0035] (1) Select a substrate 2 made of polymethyl methacrylate (PMMA) material with a thickness of 3mm, and plan a pattern area for forming a three-dimensional image on the substrate 2 according to the required pattern shape, and place the substrate 2. Send it into a semi-automatic screen printing machine, and print a dot layer 3 composed of several regularly distributed colored dots on the back of the substrate 2 by screen printing. The size of the colored dots in the dot layer 3 is determined by the center Gradually increase towards the edge, the screen line angle of the colored dots is 45°, after the printing is completed, send it to the electric heating dryer, and dry it for 25 minutes at a temperature of 52°C, and the printing of the dot layer 3 is completed;
[0036] (2) The printed substrate 2 of the colored dot layer 3 is sent to a semi-automatic screen printing machine, using a 300-mesh screen, and st...

[0039]Example 3: Production of refrigerator panels
[0040] (1) Select a substrate 2 made of polymethyl methacrylate (PMMA) material with a thickness of 5mm, and plan a pattern area for forming a three-dimensional image on the substrate 2 according to the required pattern shape. 2. Send it into a semi-automatic screen printing machine, and print a dot layer 3 composed of several regularly distributed colored dots on the back of the substrate 2 by screen printing. The size of the colored dots in the dot layer 3 is determined by the center Gradually increase towards the edge, the screen line angle of the colored dots is 45°, after the printing is completed, send it to the electric heating dryer, and dry it at a temperature of 55°C for 30 minutes, and the printing of the dot layer 3 is completed;
[0041] (2) The printed substrate 2 of the colored dot layer 3 is sent to a semi-automatic screen printing machine, using a 200-mesh screen, and still printing the reflective coating pr...
