Austenitic steels are widely used in machine and tool making, and many of the products produced are marked with ink or impact marking systems. This study aims to investigate contrast colour marking methods using advanced, environmentally friendly fibre laser systems. We developed marking matrices with 14 columns and 6 rows, each square measuring 5x5 mm. We investigated the effect of scanning speed, laser power and frequency on colour marking and surface roughness. Our results showed that increasing the scanning speed leads to a decrease roughness, resulting in different coloured markings. As the average power increased, the marking changed to different colours. At low frequencies of 50 kHz, the colour marking was observed with lower contrast saturation, while increasing the frequency to 300 kHz resulted in a more homogeneous and contrasts with brighter and more saturated colours. These results provide valuable information for improving colour marking techniques using laser systems in the manufacturing industry.
