Ordinary mechanical engraving cannot engrave thick and thin dots in an economical way, and thus does not have a grayscale presentation. Laser engraving machine is to achieve engraving in the form of dotting, has a natural advantage in the grayscale expression. For this reason, in the design of engraving as far as possible to use grayscale expression, the benefits of this is on the one hand to reduce the coloring process, saving costs; on the other hand, to enrich the means of expression of engraving, increasing the level of graphics. Users in use, first do different gray scale filling within the graphics (text to be converted into shape first), carving output select black and white mode, you can try the effect of different dots, the accuracy is generally not more than 500dpi.

Carving materials: logs (unprocessed wood) wood is by far the most commonly used laser processing materials, it is easy to carve and cut. Light-colored woods like birch, cherry or maple are easily vaporized by the laser and are therefore more suitable for engraving. Each type of wood has its own characteristics, some are denser, such as hardwoods, and require higher laser power for engraving or cutting. We recommend studying the carving characteristics before carving less familiar woods. Plywood engraving on plywood is actually not much different from engraving on wood, but there is one thing to note, the engraving depth should not be too deep. The edges of the cut plywood will also be blackened like wood, the key is to see what kind of wood the plywood is made of.

Wood carving in general, carving on wood is usually Yin carving, and carving depth is generally required deeper. This power is generally set higher, such as encountering harder wood may make the carved graphics become darker. If you want to make the color lighter, you can increase the carving speed and try to carve a few more times. Some wood in the carving will produce some soot attached to the wood surface, if the wood has been painted with a wet cloth can be carefully wiped away, if not painted may not be wiped clean, resulting in surface contamination of the finished product.

Wood cutting laser engraving machine cutting wood depth is generally not deep, the maximum cutting depth depends on the wood material and laser power, such as to cut very thick wood, can slow down the cutting speed, but may cause the wood to burn. For specific operation, you can try to use a large size lens and use the repeated cutting method. Stained wood carving will generally have a burned feeling, with the wood base color with a primitive artistic beauty, the color of the shade mainly depends on the laser power and carving speed. However, some woods are usually soft in texture and you cannot change its color no matter what (e.g. birch). For the coloring of the finished product, propylene pigments can be used.
