The process requirements: no yellowing on the surface of the lines, the bottom color of the materials should be showed, no blacking at the incision of the dermis, the engraving is clear. Materials include synthetic leather, PU leather, PVC leatherroid, Rough dermis materials, semi-products, various kinds of leather upper materials, and so on. The engraving speed is determined by sizes of graphics. The slower speed, 0.8 meter per minute, is for small pictures and the higher, 1.5-3 meters per minute, is for big pictures. The optical density 75% is enough to breakdown most leathers. The speed of dermis cutting will be slower, 0.4-1.2 meters per minute and the optical density is 60-75%.
