31 Aug Raster vs. vector
A customer wanted the look of laser engraving on wood, but the artwork provided was taking so long that it was not cost effective. After talking through what was taking so long (and consequently costing so much) we invested a little time into recreating the artwork in a way that took considerably less time.
A laser works in two different ways: raster and vector. Raster is like a deskjet printer where the laser goes back and forth over the area and engraves the image. Vector simply follows a path with the laser.
Raster engraving certainly has its place. It allows you to do large swaths of engraving with varying tones (e.g., photographs). It just takes longer because there is so much back and forth with the laser.
By converting the artwork from mostly raster engraving to entirely vector engraving, we were able to get the laser time to 6.5 minutes, down from 26 minutes. If your project does require raster engraving, see if you can limit the area to cut down on overall laser time.
