Common sources of light in life include infrared lasers, red lasers, green lasers, and lasers of various colors. Among them, infrared lasers mainly have two kinds of lasers, infrared laser diodes and vermiculite lasers. These two have obvious commonalities. They are all solid-state lasers used in plate-making machines. The technology studied in this respect is very mature, with high power and long service life. It is the main light source for thermal imaging of plate-making machines.
The thermal imaging technology is to apply laser light generated by a laser of a specific wavelength, and expose the thermal plate of the plate-making machine through a series of optical systems, so that a certain amount of energy can be accumulated on the film layer of the heat-sensitive plate material only when When the accumulated energy reaches an exact energy value per unit area of ​​the printing plate, the film layer of the plate making machine generates a thermal latent image, and after a series of subsequent processes, the exposed image can be displayed on the plate making machine.
The thermal imaging technology of the plate-making machine is characterized by the fact that there is no cumulative effect of exposure energy, and the thermal imaging relies on heat to achieve an effective conversion of the physical state. Therefore, the power of the plate-making machine must have sufficient strength to make it possible to absorb all the energy. It is conducive to the increase of the temperature in the environment, so that the exposed area reaches a temperature sufficient to change the state of matter. Otherwise, the energy absorbed by the platesetter will disappear when heat exchange with the environment, and the temperature of the material will not meet the requirements.
In short, the thermal imaging of the platesetter uses the thermal effects of photons, and the efficiency of imaging depends on the number density of photons, not just the energy carried by a single photon. This is the thermal imaging technology of the plate-making machine. There is no reason for energy accumulation.
The plate-making machine has obvious imaging power value. Only when the power reaches a certain amount of value, the transfer of the state of matter can be realized. Therefore, the thermal imaging exposure tolerance of the plate-making machine is generally very large, and the exposure is not observed in a wide range. This feature has high practical value.
