From the physical viewpoint, the morphology variation was assess based on the roughness parameters. Qualitative changes in the anatomical structure were inspected with the aid of light microscopy. Significant influences on roughness parameters have been confirmed for all the three factors acting during engraving (raster density, anatomical direction, wood species). Over the entire study range, increasing raster density caused increasing roughness parameters parallel to a well as perpendicular to the grain course. Significantly higher roughness variation was recorded perpendicular to the grain course. Significant influence of wood species on roughness parameters was explicitly confirmed in the case of roughness measuremrents perpendicular to the grain in radial direction. The most conspicuous changes were observed in spruce wood, the lowest in beech wood. The results of microscopical observations were effective for explaining the species-related differences in roughness in wood treated with a CO2 laser.
