Laser Lines has a complete range of Synrad C02 lasers which are ideally suited to 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.
In these types of applications, laser marking has several advantages over traditional ink and adhesive labels. Unlike adhesive labels, lasers create a permanent mark that cannot be removed and compared to inkjet printers, a laser marking produces a higher quality mark while eliminating consumables and maintenance issues.
This particular application demonstrated the laser’s ability to mark expiration dates at high speed on varnished, ink coated card stock using a Synrad 10W 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. In a tracking application, these packages could be marked at a rate of approximately 16 cartons per second.
