Sometimes when you engrave paper with a paper laser engraving machine, you will find that the cutting edge will turn yellow. Why is this? Let’s take a look at the reasons why the laser engraving and cutting paper turns yellow.
- There are problems with the paper itself, such as paper is made of recycled paper, and the paper is easy to yellow when wet;
- Because of the cutting rate, the slower the cutting rate, the longer the relative residence time of the heat at the same point of the paper, causing the high temperature to make the paper yellow or stick;
- The raw smoke produced by cutting has a certain temperature. If it is not smoked in time, it will easily cause the edges to turn yellow or stick to the edges. The thicker the paper, the slower the cutting, and the easier it is to cause the edges to turn yellow.
The solution to the yellow edge is to increase the cutting speed. In addition, the phenomenon of laser engraving and yellow paper cutting is solved through upper and lower ventilation and a two-pronged approach!
How is the paper carved and cut?
The principle of laser cutting paper is to use the high energy density of laser to irradiate the surface of the paper, cut the paper, and form a clear hollow pattern. Compared with the traditional method, it has the advantages of faster speed, simple operation, short time-consuming, and the pattern can be arbitrarily designed. Just transfer the desired graphics to the computer, and you can easily achieve the desired effect!
The paper laser engraving and cutting function endows paper with higher artistic value, such as greeting cards, invitations, business cards, candy boxes, stickers, calendars, gift boxes, cake wraps, cake inserts, etc. Its style is changeable, more like a work of art, which can give people a beautiful visual enjoyment!
