Below we will explain some tips for the correct glass laser engraving.
INTRODUCTION TO GLASS LASER ENGRAVING
There is a wide variety of products made of glass: glasses, glasses, bottles, mirrors, tables, trophies, etc.
Products that we can easily customize with a laser engraving machine to give it high added value.
When the laser hits the glass, it breaks the surface of the material giving it an appearance like frozen glass.
The results, however, may vary depending on the type of glass we are going to engrave. Next we explain how to get a fine finish without roughness or heterogeneous tones.
GLASS ENGRAVING TECHNIQUES
The parameters recommended to produce a smooth finish are:
Low resolution: If you use a rather low resolution (300 dpi or less) when recording more separate points, you will get a better result.
80% Gray: Make sure that the design does not contain anything black, but an 80% gray for a better quality in engraving.
Jarvis Pattern: This pattern also helps to achieve a finer engraving. Activate it in the Epilog print driver.
Mask the glass: Use a newspaper cutout of a size slightly larger than the design you are going to engrave. Wet it lightly with water and stick it on the surface to be etched. Make sure there are no wrinkles left. This will help dissipate the temperature on the glass surface during etching.
Dish soap: You can put a thin layer of soap on the glass. In the same way as paper, it will dissipate the temperature on the glass surface during etching.
Finally, you should keep in mind that there are some glasses with a higher lead content. In these cases, the glass may explode to the usual parameters. For this type of glass we recommend using a lower engraving power.
