Step 1

Step 1: Import design

The first step is to either make your own design or import our ready made template. Send the job to the laser software using the driver settings below.

Print settings

Process mode	Resolution	Cut line
Standard	1000 dpi	none

Halftone	Others
Colour	-

TIP:

We used the highest resolution possible of 1000 dpi for our graphics during the laser engraving job.

Step 2

Step 2: Engraving the marble

Prior to processing wash off the natural dust on the stone using running water. Once dry, position it onto your laser machine bed and focus on the material surface. If the stone is rounded, focus on the average value of the engraving area. Next you need to create the material parameter settings, which will vary depending on your laser machine and its available laser power.

LASER PARAMETERS - LASER ENGRAVING:

Colour	Process	Power (%)	Speed (%)	ppi/Hz
black	Engrave CO₂	50	20	1000

Passes	Air Assist	Z-Offset	Advanced
1	on	- 0.5 mm	-

INFO:

We used a negative offset value as this exposes the surface to more laser power, resulting in the engraving showing a greater contrast.

Step 3: Cleaning

Clean the debris from the marble with a damp cloth. Unlike pre-processing this time you shouldn't put the marble under running water, as this might wash out the engraving dust which ensures the contrast is visable.
