Why is my laser engraving machine lettering distorted?

Laser engraving machines are a novel way of working with materials, changing the way designs used to be made on a variety of materials, from wood to metal to plastic. However, sometimes you may notice that the text on your engraved product is distorted or not as clear as you would like it to be. This can be frustrating, especially if you are using the machine for professional purposes. In this article, we will discuss some of the common reasons why laser engraving machines may distort lettering and what steps you can take to fix these problems.

Reasons of font distortion

Incorrect focus

One of the most common causes of text distortion in laser engraving machines is incorrect focus. When the laser beam is not properly focused on the surface of the material being engraved, the engraved type will not be as clear and precise as it should be.

Low power setting

If the laser power is not high enough, the material may not be engraved cleanly, resulting in blurred or distorted text.

No cleaning of lenses or mirrors

Over time, the lens and reflector of a laser engraver can become dirty, which can lead to distorted engraving. Dirt or debris can cause the laser beam to scatter or deflect, resulting in blurred or distorted lettering.

Incorrect software settings

The software settings of the laser engraver play a crucial role in the quality of engraving. If the software settings are not correct, it may lead to font distortion.


In short, laser engravers are excellent tools for creating high-quality designs on a variety of materials. By understanding the common causes of distortion in engraving, you can take steps to solve the problem and create clear and precise engravings. Of course, you also need to maintain your laser engraver by keeping the lens and reflector clean and adjusting the focal length and power settings to suit each material.
