Black granite provides the best surface for photo engraveture. The grain structure in selected black granite is very fine, providing a superior background for details. The size of an engraved project depends on the ability to handle the large pieces of stone. Several panels can be used together to create a large project. Many other types of stone can be photo engraved, including limestone, marble and also glass.
Photo engraving on stone requires a smooth finish.
The actual depth of the engraving is approximately 3mm. When there is a need for more deeply engraved text or line-art, the engraving process is adjusted. Photographs cannot be rendered with a deep engraving. Line-art and larger text are most suitable for deeper engraving. The width of line and distance between lines determine the depth of the engraving.
