A very compact and economical CO₂ laser engraving system to make relief plates for the purpose of printing corrugated cardboard has been developed. This system consists of a highly stable 500W CO₂ laser and a high speed, easy handling image processing sub‐system. In this paper several new developments are described. This image processing technique for CO₂ laser raster scanning and engraving has been newly developed. Every binary image is converted to the relief plate more easier than other reported engraving systems.
