The purpose of this document is to help each engraver get an idea as to how to engrave on Gravotech laserable materials. The parameters are sorted by product range. Every material can have up to 3 different types of engraving process: • Vector, for lightweight linear tracing • Raster, for heavy marking • Cutting Some materials may not be engraved with a certain type of engraving process: if the specific type is not in the grid of the material, then it's most likely that it we do not recommend this engraving method on the indicated material.

Gravogrip™ : • Use Gravogrip™ when engraving on thin materials as they can have uneven surfaces. • Avoid using too much power when engraving to prevent damage to the Gravogrip™ plate. Note : in case of unexpected behavior during the engraving process, please refer to the machine's User Manual for troubleshooting. METALLICS MATERIALS CO2 LASER PARAMETERS 149
