An important factor for high-quality laser engraving is image resolution. Photo resolution must be at least 333 dpi. If necessary, you can increase the resolution in your graphics editor by changing the raster (bitmap or for CorelDraw resample).
For example, photos from the Internet usually have a resolution of 72 dpi. Even such images can be engraved on a laser if the original layout is larger and has been modified to a smaller size.
We do not recommend increasing the small photos, as it worsens the resolution. This makes the raster too large. This option is not suitable for high-quality laser engraving.
how to engrave photos by lasers. The choice of the parameters depends on:
• the material for the engraving;
• laser power;
• the image itself.
The quality of engraving depends on the type of material. The selection of the resolution for a particular type of material is very important for the quality of laser engraving.
For example, anodized aluminum can be engraved at a resolution of 600-1000 dpi because the raster points do not increase on the material during laser processing.
For wood or glass 333 dpi is enough, as each point of the raster when engraving becomes more than in the graphics editor. This is due to the surface quality.
For acrylic or laminate suitable resolution 500-600 dpi.
In most cases, a lower resolution of the photo (333-500 dpi) is sufficient for laser engraving of the image on plastic, as the raster points do not overlap each other.
