Gravure printing presses laser engraving works with the rapid development of optoelectronic technology, laser engraving technology applications more and more widely, more and more demanding engraving accuracy. The four most fundamental elements that affect laser engraving are: engraving speed, laser power, engraving accuracy, and material. In the specific material to achieve a certain degree of carving effect, it requires a certain energy absorption of the laser, the energy should be seen as the material absorbs the laser energy = laser power / engraving speed.
Simply speaking is to improve the absorption of laser energy materials, it should increase the laser power or reduce the engraving speed, as to say that the last method to use depends on the material and the final carving effect. In general, users will avoid high and low speed, because it will reduce the production efficiency. In fact, the impact of carving efficiency is not only the carving speed, carving accuracy also has a very big impact on it
This is the principle of laser engraving for gravure printing.
