Colour Laser Marking Stainless Steel

In this guide we show you how to colour mark stainless steel, making use of the Wimbledon logo. This can be applied to bottles, nameplates, flasks, and much more.

Replicating colours with laser marking can be a challenging process, especially if you are intending to get as close to the original logo as possible.

This laser marking process will likely require multiple passes and well refined parameters alongside a high quality MOPA fiber laser with a good selection of waveforms, and an exceptionally accurate, stable z-axis.

There are of course other ways of producing colour marks on metal such as sublimation, UV inks or other printing methods, but these can rub off easily, use polluting consumables and can be inconsistent. Laser gets around this.

Alignment & Trial Run

To ensure the graphic is placed where you want it, you may also draw an outline around the graphic and send it to the laser with 100 speed and 0 power, then turn on the red dot pointer.

Parameters & Marking

To create a black mark on anodised aluminium, you need a 20 watt MOPA laser source. We recommend using the F-254 lens because it perfectly fits the spot diameter for this application. Below are some of the parameters we used, if you would like to know more please speak to a material specialist using the link below.

Laser Tips

Achieving a higher quality mark

With a MOPA laser source, you can set very short pulse durations. This is the secret to creating black marks on anodised aluminium, as the short pulse durations do not damage the surface of the material. The anodised layer is not removed, simply repainted. Whilst the process of black marking is completely different from the production of tempering colours on stainless steel, a comparable result is created. You can set the filling line distance to adjust in a wide range of various shades of grey up to black: The smaller the distance, the darker the laser marking result.
