Laser engraving technology is increasingly prevalent in the graphics engineering industry due to its speed, precision, and capacity for individualization. This method is widely used for decorative metalwork, metal packaging, and signage, providing high-quality aesthetic results on various surfaces. This study investigates the impact of different laser engraving parameters, such as speed, hatching, frequency, and power, on the colorimetric properties of steel surfaces. The experiments were conducted using a fiber laser with a power of 30W and a wavelength of 1064 nm on polished steel plates measuring 20 x 20 cm with a thickness of 4 mm. Engraved samples, each measuring 5 x 5 mm, were produced, with laser parameters varied for each sample. After engraving, each sample was analyzed under a microscope and measured using a spectrometer to accurately determine colorimetric values, offering precise quantification and analysis. The results indicate that engraving speed significantly affects the depth and intensity of color, with lower speeds allowing deeper oxidation and more saturated colors. Increased laser power generates greater heat, resulting in more vibrant color tones. The frequency and pulse duration of the laser influence energy distribution and heating patterns, with shorter pulses producing precise changes in colorimetric properties and longer pulses causing deeper alterations. The hatching pattern also affects the colorimetric properties due to variations in heat distribution and energy absorption. High temperatures are critical for color formation as they facilitate the oxidation process, where the oxide layer's thickness and composition determine the final color. These findings enable designers and technicians in the graphics engineering industry to control the aesthetic aspects of steel engraving with greater precision. Moreover, the results of this study could be utilized to develop software for the automatic adjustment of engraving parameters to achieve desired color images on steel surfaces. Such software would significantly enhance the efficiency and effectiveness of laser engraving processes, offering new possibilities for creative applications in the design of metal packaging and signage. By integrating these insights, the graphics industry can achieve more consistent and high-quality outcomes, driving innovation and expanding the potential uses of laser engraving technology.
