How to carve cards? What is the specific process?

Carving processing technology has the characteristics of high processing precision, high degree of automation, fast processing speed, high processing efficiency and simple operation. , adapted to the development trend of papermaking technology, so laser engraving technology is being popularized and popularized in papermaking industry at an alarming speed. For example, laser engraving, first of all, is non-contact processing, which has no direct impact on greeting cards, so there is no mechanical deformation. Secondly, there is no "tool" wear in the laser cutting process, the greeting card material loss is small, and the product defect rate is extremely low. Moreover, in the laser cutting process, the laser beam has high energy density and high processing speed, and has no or little influence on the non-laser irradiated part of the greeting card.
