Laser Lines Ltd offers the complete range of Synrad C02 lasers suitable for ablating many common inks used on card stock packaging for consumer items. The CO2 wavelength typically bleaches out the ink, leaving behind a crisp white mark. This type of mark is achieved at very quick velocities even at low laser power and is perfect for marking ID information or expiration dates. This particular application demonstrated the laser’s ability to mark expiration dates at high speed on varnished, ink coated card stock using a Synrad 10 W laser and an FH Flyer marking head. The resulting high-contrast mark was completed in a cycle time of 60 milliseconds. The laser mark bleaches the ink coating providing a crisp white mark which has excellent contrast with the ink color.
