Laser Marking Discoloration

Laser-marking-contamination poses removal challenges in cleaning applications because organic residues form irregularly during marking. After exposure to laser energy, layer builds up on surfaces and adheres tightly to metals, creating patchy patterns that resist uniform ablation. So, cleaning requires precise pulses to avoid substrate damage. On polymers, contamination spreads evenly but peels off easier because of lower adhesion. In observations, material-specific behaviors show metals hold residues denser, while organics loosen faster under heat. Treatment achieves clean surfaces effectively, and results come from scans showing reduced buildup. This process handles patterns well during short exposures.
