Printing Ink Residue Contamination

Ink-stains contamination, it arises from pigmented deposits of industrial printing, markers, and spray paint that adhere through solvent evaporation and penetration. This pattern distinguishes itself by irregular pigmentation and strong bonding, unlike uniform rust or dust layers, and on porous paper or cardboard, it seeps deeply while on durable steel or concrete, it forms tenacious surface films. Removal challenges include chemical resistance and substrate damage risk, thus laser cleaning excels as pulsed energy vaporizes stains selectively and restores material integrity without abrasion.
