The working principle of laser engraving of the printing technology of gravure printing machine is that with the rapid development of optoelectronic technology, the application range of laser engraving technology is more and more extensive, and the precision of engraving is getting higher and higher. The four most fundamental elements that affect laser engraving in gravure printing machine are: engraving speed, laser power, engraving accuracy, and materials. In order to achieve a certain engraving effect on a specific material, it is required to absorb a certain amount of laser energy, which should be regarded as the laser energy absorbed by the material = laser power / engraving speed.
Simply speaking, to increase the laser energy absorbed by the material, the laser power should be increased or the engraving speed should be reduced. As for the final method, it is necessary to look at the material and the final engraving effect. In general, users will avoid high and low speeds, because that will reduce production efficiency. In fact, it is not only the engraving speed that affects the engraving efficiency of the gravure printing machine, but also the engraving precision has a great influence on it.
This is how laser engraving works in the printing technology of gravure printing machines.
