At Engrave Goods we’ve found laser engraving to be the ideal method to mark leather and have spent nearly ten years experimenting with and perfecting the technique on leather and wood. Laser engraving is a unique marking method that is often overlooked and misunderstood in comparison to more popular printing and embossing techniques, so let’s take a closer look at how the process works and what results can be achieved.
How Laser Engraving Works
In the most basic sense the process of laser engraving is similar to using a magnifying glass to create a point of light from the sun to start a fire. In this case, instead of the sun, the laser engraving machine uses electric current to create a high intensity beam of infrared light. The beam is directed to a moving laser head by a series of mirrors. The laser head contains two important parts (1) a mirror which directs the beam downward toward the surface of the material to be engraved and (2) a focus lens which concentrates the energy of the beam into a very fine point at the surface of the material (in our case a piece of leather or wood). This point of concentrated energy burns and removes material creating an engraved mark. The engraving machine translates photos and graphics that we prepare on the computer into engraved marks on leather and wood.
What Can Be Engraved
We utilize a Trotec Speedy 400 laser engraver with an engraving area of 39” x 24”. There are some limitations on the minimum detail and lineweight sizes (minimum .6pt line weight and 6pt font size) and it’s important to keep in mind that you will lose some contrast when going from digital image to engraving. But within those limits, we’re able laser engrave virtually any high quality image file or vector graphic.
Greyscale images are engraved by translating the images into a halftone dot pattern where the density of engraved dots creates the look of shading and grey tones. Each individual dot is very small so we’re able to translate a high level of detail into the engraved images. You can see an example of this in the photo below.

Comparison to Other Marking Techniques
Below are pros and cons for three of the most popular marking techniques - laser engraving, printing, and embossing - in regards to marking on leather and wood.
