Laser engraving is the process of using a laser to etch or mark the surface of a work piece. One of the advantages is that Laser Engraving can be extremely precise.
A laser is a device that emits light through a process of optical amplification based on the stimulated emission of electromagnetic radiation. The term "laser" originated as an acronym for "light amplification by stimulated emission of radiation".
A laser engraving machine can be thought of as three main parts: a laser, a controller(the computer), and a surface. The laser is like a pencil - the beam emitted from it allows the controller to trace patterns onto the surface. The controller direction, intensity, speed of movement, and spread of the laser beam aimed at the surface. The surface (the product) is picked to match what the laser can act on.This technology can be useful for many applications and can utilize many materials.
Laser Engraving uses a computer into which the specific designs are put and through which the engraving commands are carried out. The engraver is controlled by computer software that is vector based (example of software would be adobe illustrator or corel draw). The software reads lines not dots so images that are bitmaps such as jpg, png, pdf need to be converted to vector.
Laser Engraving can also be done on stainless steel as long as you use a product called cermark. What is the CerMark Process?
The CerMark process utilizes marking materials, or “inks,” available in various forms, which are applied to surfaces to be marked. The ink is then selectively fused – using patented laser marking technology - to the surface with a regular industrial marking laser. Finally, any excess ink is easily cleaned from the surface. The inks are scientifically formulated to make a permanent, chemical bond to surfaces, without compromising or damaging the material being marked.
