Embodiment Construction
[0045] The principle of the present invention is that, according to the definition of printing screen, dots are the smallest copy unit for reproducing printing effects, and accurately controlling the transfer and copying of dots is an effective way to control printing quality. The dot coverage area is the area of the dot inking area in the printing unit grid, and the ratio of the area of the inking area in the unit grid to the grid area is the dot area ratio. Different dot area ratios in the printed manuscript ultimately reflect different printing tones. The traditional way to measure the dot area ratio is: measure the incident luminous flux and reflected luminous flux, and then convert and calculate the dot area ratio. The development of computer virtual reality technology has realized the simulation of light propagation process in different media. According to the definition of physical optics, light has wave-particle duality. Based on the particle properties of light, ...
