Due to the large number of variables involved with laser marking there is no magic formula to determine the precise settings for your specific laser set-up.

Laser Variables Effecting Marking

  • Lasers wattage
  • Type of the optics employed
  • Quality and cleanliness of the optics employed
  • Quality of the laser beam
  • Laser beam spot size
  • System software used

Material Variables Effecting Marking

  • The type of substrate,
  • Thickness of the substrate
  • The substrate’s ability to conduct heat

Fortunately, there is a simple and reliable method to determine your specific settings.

Step 1) Obtain a sample of the substrate material that you will be marking on. The sample should be made from the same material and should be the same thickness as the final piece; otherwise some variation in settings may be required. 

Step 2) Apply the Enduramark laser spray to the test sample (See Application and Usage Instructions)

Step 3) Design a test marking grid using CorelDraw, Adobe Illustrator or equivalent software where P = % Power and S = % Speed. Depending on your laser wattage you may need to adjust the base settings for your grid from that shown below.

Utilize your laser software’s color mapping function to set-up the laser so each color has the settings that correspond to that color. Example: The text with RGB color settings R:255,G:0,B:0 will laser at 100% power and 60% speed; R:0,G:0,B:255 will laser at 100% power and 50% speed and so forth.

Step 4) If you are not using a laser with an auto-focus or do not want to utilize the auto-focus, make sure the laser focus setting are appropriate and then laser the test grid onto the test sample.

Step 5) Remove the residual marking spray with a sponge and water and evaluate the marks (We recommend using a Magic Eraser since it is slightly abrasive and will remove weakly bonded or flawed marks that are not as easily removed with a standard sponge).

Step 6) Evaluate the marks. The sample to the right shows that at speeds 60 and 50 the marks adheres very poorly. Speed 40 shows improvement but is still partially removed upon abrasion. Speed 30 shows some slight speckling from a small percentage being removed. Speed 20 through speed 5 all give high quality marks but it is unnecessary to run at a speed slower than 20 in this example.
