In raster engraving, the laser head passes horizontally from left to right across the surface of the material, similar to how printers function, however, light is used instead of ink and this heats the surface either detaching or fragmenting from the rest of the surface to vaporise the material away. A high level of detail is achieved by the laser. The filled sections of the design are engraved entirely and greyscale areas will be engraved with less depth than higher contrast areas and white is left untouched.

The Raster Engraving Process

The laser beam engraves the text or design line by line and point by point from a start to finish point, which is a similar process to how a printer works, but instead of using ink only magnified light is used producing incredibly detailed results. The process can also be referred to as bi-directional in which the engraving is carried out in an alternating fashion in both directions.

This Laser Engraving process works on virtually any material, including wood, acrylic, leather, laminates, MDF, cork, paper, ceramics, coated metals and textiles.
