The use of Lasers for colour marking is not a particularly new technique as it has been recognised for over 10 years.
This technique was originally identified as a viable process for use on craft metal work and jewellery.
However, the process has had very little commercial impact in the intervening years.
There is now a greater interest in this process as manufacturers of consumer goods are looking for new techniques and finishes to provide product differentiation.
This application insight looks at a variety of materials that are colour mark-able including titanium and stainless steel, and explores the benefits and parameters of the Pulsed Fiber Laser in relation to this application area.
