s1.4, forming a shading ink layer 7 on the lower surface of the back substrate layer 6, and printing high-temperature-resistant shading screen printing ink on the back surface of the back substrate layer 6 to form the shading ink layer 7 with a developing pattern. For step S1.4 the following steps are included: s1.4.1, preparation before printing: selecting a 150-plus-200-mesh screen plate and high-temperature-resistant shading screen printing ink for later use; s1.4.2, screen printing: placing one surface of the back substrate downwards on the surface of a printing workbench of a screen printing machine, starting the screen printing machine, and printing a developed pattern on the back substrate by using high-temperature-resistant shading screen printing ink; s1.4.3, curing the printing layer ink: and putting the whole printed back substrate into an IR heating constant-temperature baking tunnel furnace, and continuously baking for 30 seconds at the temperature of 90 ℃.

For the cover plate with the chess backlight indication, the back substrate layer 6 and the priming printing light scattering layer 5 can be replaced by a PET light scattering film, and the thickness of the PET light scattering film is 0.1mm-0.25 mm. Compared with the back substrate layer 6 and the priming printing light scattering layer 5, the PET light scattering film has the advantages that the production cost can be reduced, and the production efficiency can be improved; compared with the background substrate layer 6 and the priming printing light scattering layer 5, the PET light scattering film has the defects that the PET light scattering film covers the shading ink layer 7 completely, and pattern shadows cannot be hidden and covered completely, namely the covering effect is limited.

Although the expression effect is slightly inferior to the two schemes, the purposes of reducing the natural appearance lines and the beauty of the natural plant skin and improving the visual effect can be still achieved.
According to the manufacturing method of the cover plate with the chess playing backlight indication, provided by the invention, the surface hardening treatment of the step 1.8 can be adjusted to the step S1.9.4, and the transparent protective film layer 12 and the natural plant cortex layer 3 are synthesized and then carried out.
