Question- I use the same settings specified by TherMark and I get terrible results. What can be wrong?

Answer-  There are a number of circumstances which can cause this:

For exactly same situation described you may get bad results due to being out of focus. See above.

The coating thickness makes a huge difference, too. Try a few different coating thicknesses to get the best results.

Check which kind of lens you are using. Different lenses with different focal lengths will have different beam waists at the focal plain, requiring different power and speed settings.

A common error is failure to perform the proper conversion of settings. Settings are often given in percentages, but 80% power on a 45W laser is not the same as 80% power on a 30W laser. Similarly, 80% speed on a laser which goes 140 in/sec at 100% speed is not the same as 80% speed on a laser which goes 60 in/sec at 100% speed. Make sure to convert percentages so they are relevant for your laser. Remember, the important thing is absolute power (Watts) and absolute speed (in/sec or cm/sec).

Mode of operation is also very important. It is important to understand the differences between rastering vs. vectoring and continuous wave vs. pulse. For more information, please visit our Laser Settings Section.

Question- The marked graphic is not sharp; lines are thicker than in the picture. What could be wrong?

Answer- A common reason for this problem is that your laser is out of focus. When your laser is focus, the narrowest waist of the laser beam is the part of the beam which hits the substrate. When you are out of focus, a wider part of the beam is hitting the substrate. Despite being somewhat out of focus it is still possible to create a bonded mark. However, the excess beam width will reduce the resolution you can achieve. In order to fix this problem, re-focus your laser. Once you bring the laser into focus you may need to reduce your laser power setting.

Question- Can you screen-print the LMM-6000 or LMM-14?

Answer- NO! This is not recommended.

Question- The laser marking materials look great after laser marking them, but when I go to rinse them off they wipe clean. What am I doing wrong?

Answer- Usually this means you are not allowing the laser enough time to bond the materials to the substrate. You can adjust by lowering the marking speed (expressed in %, in/sec, or cm/sec). We recommend this be done in 5% increments. A power grid on a sample piece may help to visualize the settings better.

Question- I get inconsistent marks after marking. Different parts of the graphics have different contrast and quality.

Answer- This may happen when the coating of CerMark materials is not homogeneous along the surface being marked. This usually occurs when airbrushing or foam brushing our liquid products. Care must be taken to master a technique which works for you so you can evenly apply the ink along the whole target surface every time.
