Ordinary mechanical engraving is unable to economically engrave dots of varying thickness and therefore cannot render grayscale effects. In contrast, laser engraving machines have the natural advantage of grayscale presentation by achieving engraving through dotting.laserpecker 2 laser engraver Therefore, in the engraving design, should try to use grayscale representation. The advantage of doing so is that on the one hand, reduce the coloring process, saving costs; on the other hand, enrich the means of expression of engraving, increase the graphic sense of hierarchy. Users in the use of laser engraving machine, you can first graphic different gray-scale filling (text needs to be converted to graphics first), and then select the black and white mode for engraving output. The effect of different dots can be tried, and the accuracy is generally not more than 500 dpi.
Wood is currently one of the most commonly used materials for laser processing and is easy to engrave and cut. Light-colored woods such as birch, cherry or maple are easily vaporized by the laser, making them ideal for engraving.laser pecker 4 Each type of wood has its own unique characteristics and some denser woods, such as hardwoods, require the use of higher laser power when engraving or cutting. It is recommended that you first study the engraving characteristics of unfamiliar woods before engraving them.
Engraving on plywood is not much different from engraving on wood, but one thing to keep in mind is that the engraving depth should not be too deep.laser pecker pro The edges of cut plywood will darken just like wood, and the key depends on the type of wood used for the plywood.
In general, carving in wood is usually shaded and requires a deeper carving depth. Therefore, a higher power setting is usually required. If harder woods are encountered, this may result in a darker color of the engraved figure. If you want to make the color lighter, you can speed up the carving and try multiple passes. Certain woods produce some soot that adheres to the surface of the wood during the carving process. If the wood has been painted, the soot can be removed by wiping carefully with a damp cloth. If it is unpainted, it may be difficult to wipe it off completely, resulting in surface staining of the finished product.
The depth of wood cut by the laser engraver is generally not very deep, and the maximum depth of cut depends on the material of the wood and the power of the laser. If thicker wood is to be cut, the cutting speed can be slowed down, but this may cause the wood to burn. For specific operations try using a large format lens and a repetitive cutting method.
Wood usually has a burned look after engraving and has a raw artistic beauty that matches the wood base color. The depth of color depends largely on the laser power and engraving speed. However, some woods are usually of a softer texture and their color cannot be changed in any way (e.g. birch). For the coloring of the finished product, it can be treated with acrylic paints.
