8. The printing process of the glass panel according to claim 6, wherein a first layer of ink with a thickness of 10 μm is printed on the glass panel by a screen plate, the surface of the first layer of ink is scanned by infrared sensors arranged on both sides of the glass panel to obtain the surface layer of the first layer of ink, and the condition of bubbles is determined by comparing the surface layer with a preset first ink surface; setting a preset difference range d11-d12 to be 0.5-1um, and if the difference value of the oil level at the moment is more than 1um, the oil level cannot meet the requirement; if the difference value of the oil level is less than 0.5um, continuously applying ink less than 1um to the ink surface to obtain a new ink surface; the preset error range d111-d112 is set to be 0.2-0.4um, and if the oil level difference value is larger than 0.4um, the requirement cannot be met.
9. The printing process of the glass panel according to claim 8, wherein a second layer of ink is printed on the first layer of ink glass panel by a screen printing plate, the thickness of the second layer of ink is 12 μm, the surface of the second layer of ink is scanned by infrared sensors arranged on two sides of the glass panel to obtain the surface layer of the second layer of ink, and the condition of bubbles is determined by comparing the surface layer with a preset first ink surface; setting a preset difference range d21-d22 to be 0.6-1um, and if the difference value of the oil level at the moment is more than 1um, the oil level cannot meet the requirement; if the difference value of the oil level is less than 0.5um, continuously applying ink of less than 2um to the ink surface to obtain a new ink surface; the preset error range d211-d212 is set to be 0.3-0.5um, and if the oil level difference value is larger than 0.5um, the requirement cannot be met.
10. The printing process of a glass panel according to claim 8, wherein the first ink layer comprises, in parts by weight: 100 parts of printing ink, 20 parts of photosensitizer, 10 parts of reactive diluent and 5 parts of curing agent;
the second ink layer comprises the following components in parts by weight: 100 parts of printing ink, 25 parts of photosensitizer, 12 parts of reactive diluent and 8 parts of curing agent.
