Every type of material will react differently with every brand of laser . Each laser works differently with the same Cermark product. Our advice is to carry out tests and take notes in order to have the data record of the material to be engraved.  Use the settings as your starting point then adjust one variable at a time until you achieve the result you desire. Settings for any material are a matter of personal preference. Not every material that can be run at high speed should be run at high speed. A better mark can often be achieved by slowing your  laser and giving the laser longer to react to your material. Cermark/Thermark  guarantees its products if they are applied under optimal conditions. The results may be different according to the tests carried out and the variables considered to obtain your product.

. Test your material:

If you have a small area of the material you won’t be using, or an extra item, take advantage of this area to test out your settings by engraving a small square or cutting a small circle. You can fine tune your settings in these areas.

.Similar materials use similar settings: 

When you are working with a material you aren’t familiar with, think about a similar material and what settings you would use with that product. Most anodized aluminums will react well with similar settings, as will most plastics.

. When in doubt, start low: 

Remember, you can always re-run your job as long as you don’t move it in the machine. Let’s say you’re running a photograph in a one-of-a-kind wood plaque. Start with a lower power setting, look at the engraving, then run the project a second time at high speed and lower power a second time to add a little more depth if needed.

. Run only one part of the file:

If running a job on a new material, you can always just select one piece of the engraving, like a piece of text, and run that part first to make sure your settings are perfect before running the whole file.

.Application 

TherMark/Cermark products are mostly liquid or paste inks Most of the ink products can be applied to the substrate either by spraying or painting with a foam brush. Three of these products, LMM14, LMM6000 and New Ultra come in aerosol cans and can be used directly 

 .Clean the surface to be marked (all products) 

No matter which product and supply form you choose, the process of bonding between laser marking material and substrate occurs at a molecular level so it is important the substrate be free of all kinds of contamination such as oil, debris or coatings. It should be cleaned with a solvent such as denatured alcohol or rinsed with soap and water and completely dried. Be careful not to use a cleaning agent that leaves a residue behind. 

 .Foam brush application 

Most CerMark laser marking materials come as liquid or paste ink in a variety of container sizes. Depending on the application and the industrial setting a regular foam brush can be an easy choice for ink application. To apply the ink soak the foam brush less than 1/4 th of its length (less than 0.25”) into the container. Apply with smooth, even strokes. When applying ink with a foam brush the two most important variables to control are dilution and coat thickness.  

CerMark ink may become more viscous over time due to evaporation of its thinning agent. This problem is easily overcome by adding a small additional amount of denatured alcohol and stirring continuously until the desired viscosity and homogeneity is recaptured.  

Desired coating thickness varies by product and substrate so it is important to consult the individual page for your product for exact guidelines prior to application. Most of the time one or two coatings are enough, but for some substrates additional coats may be required. If your material coating is too thin the pigment density of the material layer will not be high enough to create an optimal mark. It is important to realize that correct coat thickness is often even more important than the accuracy of laser settings for creating optimal marks.  

After application, allow the applied marking material to dry. A fan, heat gun, or hair dryer can be used to accelerate the process to 10 seconds or less. It is important the marking material be completely dry prior to laser marking.

.Aerosol spray application 

Three CerMark products are for sale as aerosol sprays: New Ultra, LMM14 and LMM6000. Aerosol cans attract many customers due to their relative ease of handling stand alone nature. All of these products are also available as liquid/paste ink, but aerosol cans have the added benefit of removing the variable of dilution. However, aerosol products still require some experimentation to learn the application process and generate reproducible and consistent results.  

Shake the aerosol can thoroughly before use . Spray uniformly at a 10” distance from the surface and move the nozzle from one side to the other covering the whole substrate area. Start spraying away from the area to be marked and move towards the opposite side and past the target area. Over-spraying before and after the target area allows constant velocity of movement and will help provide an even coating on the substrate.  

Again, desired coating thickness varies by product and substrate so it is important to consult the individual page for your product for exact guidelines prior to application. One or two coatings are typically enough. If your material coating is too thick it will absorb too much laser energy and fail to bond to the substrate. If your material coating is too thin the pigment density of the material layer will not be high enough to create an optimal mark. It is important to realize that correct coat thickness is often even more important than the accuracy of laser settings for creating optimal marks.  Allow the applied marking material to dry. 


.Airbrush spray application 

CerMark liquid/paste inks can be diluted to a viscosity appropriate for airbrushing. This method is preferable to foam brush application for any job larger than a few parts. In industrial settings, air brush application should be carried out in a spray booth with fume extraction, or, at minimum, in a well-ventilated area with a breathing mask. 

A standard air brush (such as Smart Jet from IWATA) generates good results, and you may customize your spray pattern by adjusting the nozzle of your air brush. Application considerations are the same as above in the Aerosol spray application section.   Instructional videos
