Introduction

CO2 laser marking is a widely used technique for marking various materials, including surfaces with ink. This technology facilitates quick and permanent marking solutions ideal for numerous industrial applications.

Working Principle of CO2 Laser Marking

CO2 lasers operate at a wavelength of 10.6 micrometers, suitable for marking organic materials, including ink. The laser beam focuses on the inked surface, and its high-energy photons interact with the ink particles, causing a thermal reaction that alters the ink’s visual properties. The process can create vibrant contrasts between the marked and unmarked areas, resulting in clear and durable markings.

Parameters Affecting Marking Quality

Several parameters influence the effectiveness and quality of CO2 laser marking on ink:

• Power Output: Typically ranges from 10 to 60 watts. Higher power levels can increase marking speed but may affect precision.
• Marking Speed: Adjusting speed can control marking depth and clarity. Common speeds range from 50 to 500 mm/s.
• Spot Size: Determines beam focus; smaller spot sizes allow for more detailed markings.
• Wavelength Compatibility: Proper adjustment ensures optimal energy absorption by the ink.

Specific Numerical Analysis

The efficiency of CO2 laser marking on ink can be quantified using specific parameters. For instance, using a 30W laser at 100 mm/s, with a spot size of 0.1 mm, results in an energy density of approximately 600 J/cm². This setting yields optimal marking quality on typical ink compositions, providing a contrast ratio of 5:1 between marked and unmarked areas.
