Section 12: Speed and Power
Recommendations
Anodized Aluminum
 20 - 40% Speed
 80 - 100% Power
 1 - 15% Frequency
 Up or down .030" to .050" focus
 600 DPI
The contrast / brightness of mark achievable on the FiberMark are excellent and are
often times much brighter than those done on a C02 laser. The key is to broaden the
beam by changing the focal setting by 30-50mils. This prevents the beam from
ablating the anodized coating and penetrating the metal (results in dull white/gray
marks). Lower frequency and higher power settings help offset the change in focal
point.
Different grades of anodized & core aluminum alloy will affect how the final marks
look. Finding the right printing parameters is key in achieving a highly contrasting
mark.
Precious Metals
Any rare metal alloy is deemed precious. As mentioned earlier, we've yet come
across a metal which could not be marked. This includes the rare "Grammium", metal
alloy used in casting a Grammy award. Regardless of rarity or value, the FiberMark
can mark it. Depending on the marking requirements, use one of the above settings to
get started.
