Raster Engraving; Vector Cutting - Roland LV-290 User Manual

6.1 Raster Engraving

A CO2 laser engraver can process text, scanned image, digital picture, or design by "laser firing" grids /dots of
individual pixels into a raster image. Think of this as simply "printing" your job onto any particular material. An
example of a raster engraved piece would be a photo engraving on tile, as shown in the picture below.

6.2 Vector Cutting

A CO2 laser engraver can process text, design, and images composed of lines through continuous-firing of the
laser to cut out various shapes. When performing vector cutting operations, imagine the laser head as a pair of
scissors cutting out the lines specified in your design. An example of a vector cut piece would be a customized
dining mat, as shown in the picture below.
The LV-290 Printer Driver determines which sections should be raster engraved or vector cut based on the
outline width of that particular area or section of the design. In order to prep a particular section for vector
cutting, you will need to set that object's fill color to white and set its outline thickness between 0.001" (0.025
mm) to 0.004" (0.1 mm) via the graphics software.
