Photographs and lettering on stone
Stone engraving is a raster process: the laser works across the surface and the image is built from the tonal response of the stone rather than from a cut line. That is why the result depends on the stone itself — granite, marble and slate each respond differently, and the same file looks different on each. The machine’s job is to hold the focus and the bed steady across a heavy slab.
Heavy-duty steel bed
- The bed is built to carry full stone slabs without deflection.
- A rigid bed is what keeps focus constant across a large, heavy workpiece.
Photographs, images and text
- Engraving works from bitmap photographs as well as vector lettering.
- The result is permanent because the image is in the stone, not applied to it.
Stone and ceramic range
- Marble, granite, slate, basalt, jade, ceramic tile and glass.
- Also used on plastic, acrylic, PVC board and bamboo.
Wide processing range
- The bed and gantry are sized for slab and monument work.
- Layout is planned with the largest slab you handle.
Simple operation
- Control follows a standard CO₂ engraving workflow.
- Files come from common graphics formats; jobs are stored for repeat orders.
CO₂ laser source
- 10.6 µm wavelength, the standard for stone and non-metal engraving.
- Power class is confirmed against your stone sample.
Applications
Memorial and stone work
Used where stone is the product, and where the image or lettering is the value being sold.
Materials
Marble, granite, slate, basalt, jade, ceramic, glass, plastic, acrylic, PVC board and bamboo. Stone response varies by type and finish: polished granite, honed marble and rough slate all produce different contrast from the same file, so a sample of your stone is tested before the power class is fixed.
Process notes
Setting up the engraving
Stone engraving has no single parameter table: contrast depends on the stone type, its finish and the image. Send a sample slab with the artwork and HODA engraves it and returns the result.
Contrast comes from the stone
On stone the laser does not cut an outline — it changes the surface so the image reads by contrast. Polished granite gives a light mark, darker stone gives more contrast, and slate behaves differently again. Because of that, the practical setup is: send a piece of the actual stone with the portrait or lettering, and the power, resolution and bed layout are fixed from the engraved sample rather than from a catalogue figure.
