How to solve the yellow edge problem when laser cutting and engraving paper?

Sometimes when you use a paper laser engraving machine to carve and cut paper, you will find that the cut edges will turn yellow. Why is this? Here we will take you to understand the reasons why laser equipment turns paper yellow when it is cut and carved.

1. Problems with the paper itself. For example, if the paper is made of recycled paper, the paper will turn yellow easily when it gets damp.

2. Due to the cutting speed, the slower the cutting speed, the longer the relative residence time of the heat at the same point of the paper, resulting in high temperature causing the paper to turn yellow or sticky.

3. The smoke generated by cutting has a certain temperature. If it cannot be extinguished in time, it will easily cause the edges to turn yellow or sticky. 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 solution to the phenomenon of laser engraving and yellow paper cutting is to ventilate up and down and use a two-pronged approach!

How is paper carved and cut?

Laser cuttingThe principle of laser cutting is to use the high energy density characteristics of laser to irradiate the surface of paper, cut the paper, and form a clear hollow pattern. Compared with traditional methods, it has the advantages of faster speed, simple operation, short time consumption, and arbitrarily designed patterns. As long as you transfer the desired graphics to the computer, you can easily achieve the desired effect!

The paper laser engraving and cutting function gives paper a higher artistic value. For example, greeting cards, invitations, business cards, wedding candy boxes, stickers, calendars, gift boxes, cake surrounds, cake inserts, etc., which are hollowed out and engraved by laser engraving and cutting machines, have various styles and are more like works of art, which can give people a beautiful visual enjoyment!
