Color on Glass / Ceramic
Colored Marks on Challenging Substrates
CerMark/TherMark offers several products specially engineered for optimal laser marking of glass and ceramics. These products are scientifically formulated to create a permanent chemical bond to glass or ceramic surfaces.
Marking glass or ceramic with traditional methods is a significant challenge. Current marking methods tend to produce low-contrast gray marks. Chemical etching processes can be time consuming and involve using highly toxic materials. Direct marks with a CO2 laser are made by creating ‘micro-fractures” which frost the glass but can compromise the strength of the substrate.
CerMark/TherMark’s patented laser marking materials create extremely high quality marks while protecting the glass or ceramic surface from damaging laser energy. The contrast, resolution, and durability of these marks make CerMark/TherMark materials ideal for these common applications:
Industrial
- Decorative and brand marks on sanitary ware
- Logos and markings on industrial glass
|
Awards & Engraving
- Glass trophies and awards
- Designs on plates and dinnerware
- Personalization of mugs and cups
- Designs on ceramic tiles
|
The visible color of the resulting mark may vary with the material being marked.Some experimentation and adjustment may be appropriate to obtain the highest color quality for the marking situation.
Compatible Substrates
The process window for creating high quality marks may vary depending on substrate composition and/or thickness, application method, and laser type.
Product Recommendations
All LMC products come as liquid inks which can either be foam brushed or sprayed through an airbrush. Airbrush is preferable as it generates a homogeneous coating over the substrate. These products are ideal for generating high contrast color marks on a variety of glass or ceramic substrates. They work especially well with solid state laser sources.
Laser Recommendations
Although CO2 and solid state lasers both work for marking glass and ceramic, if you are concerned about micro-fractures, it is prudent to avoid using a CO2 laser. For marking glass & ceramic, we recommend a minimum of 15W of power for CO2 lasers, and 5W of power for solid state lasers.
Feel free to consult our Choosing a Laser section for more information on choosing a laser.
Marking Time
Exact marking times will vary depending on your choice of CerMark/TherMark material, substrate composition, substrate thickness, and laser power. For more information on cycle time, click here.
