¶ 1. What is Bitmap Engraving?
- Bitmap files are made up of pixels, and each pixel's brightness determines the laser's energy output. Typically, darker pixels correspond to higher laser power, resulting in deeper engraving on the material.
- Bitmap engraving is also called raster engraving. It works similarly to an inkjet printer: the laser converts the image into a grid of dots and scans line by line. The laser power is adjusted for each point according to the pixel's brightness, producing a varied depth effect across the material.
Tip: Aliencell Space supports the following bitmap formats: BMP, JPEG, PNG, JPG
By default, bitmap images are set to engraving mode.
¶ 2. What is a Vector File?
- Vector files are made up of points and paths defined by mathematical formulas. Unlike bitmaps, vectors maintain sharp edges and clarity at any scale without distortion. Vector files can be processed for cutting or engraving.
Tip: Aliencell Space supports the following vector formats: SVG, DXF
-
Vector engraving uses the laser to follow the paths defined in the vector file. There are three main vector processing modes:
- Line Engraving: Traces the path outline, ideal for contour engraving or cutting shapes.
- Fill Engraving: Fills closed areas with engraving according to specified parameters, suitable for shading or larger surface areas.
- Color-Mapped Engraving: Automatically adjusts laser power or engraving depth based on the RGB color of the vector paths, allowing different colors in the same design to produce different engraving effects.
