Ordinary mechanical engraving cannot engraving dots of different thicknesses in an economical manner, so it does not have a grayscale expression. Laser Engraver implements engraving by dots, which has a natural advantage in grayscale expression. For this reason, the grayscale expression form should be used as much as possible in the engraving design. This has the advantages of reducing the coloring process and saving costs on the one hand, and enriching the expression means of engraving on the other hand, and increasing the level of graphics. When users use it, first fill the graphics with different gray levels (the text must be converted into graphics first), and select the black and white mode for engraving output. You can try the effect of different dots, and the accuracy is generally not more than 500dpi.
１. Logs (unprocessed wood)
Wood is by far the most commonly used laser-processed material and is easy to carve and cut. Light-colored wood like birch, cherry or maple is easily vaporized by laser and is therefore more suitable for carving. Each kind of wood sign making has its own characteristics, and some are denser, such as hardwood, which requires greater laser power when carving or cutting. We recommend that you study the carving characteristics before carving less familiar wood.
２ 、 Plywood
雕刻 Carving on plywood is not much different from engraving on wood, but it is important to note that the engraving depth should not be too deep. After cutting, the edges of the plywood will be black like wood. The key is to see what kind of wood the plywood is made of.
Wood carving
Generally speaking, the carving on wood is usually Yin Yin, and the carving depth is generally deeper. In this way, the power is generally set higher. If it encounters harder wood, the color of the engraved graphics will become darker. If you want to make the color lighter, you can increase the engraving speed and try to engrav it several times. Some wood will produce some oil fume on the wood surface when carving. If the wood has been painted with paint, you can wipe it off carefully with a wet cloth. If it is not painted, it may not be cleaned and the surface of the finished product will be stained.
Wood cutting
Laser Engraver generally does not cut wood deep. The maximum cutting depth depends on the wood material and the power of the laser. If you want to cut very thick wood, you can slow down the cutting speed, but it may cause the wood to burn. For specific operations, you can try using large-sized lenses, and use repeated cutting methods.
Coloring
After wood carving, there is generally a feeling of being burned. It has an original artistic beauty when matched with the wooden background. The depth of the color mainly depends on the laser power and carving speed. But some woods are usually the softer ones, and you can't change their color anyway (such as birch). For coloring the finished product, acrylic pigments can be used.
