DataLase Features Laser-Based Alternative for Case Marking

DataLase’s Casemark laser-based color-change marking solution is an alternative to print-and-apply labels and case label ink-jet printing.

DataLase has launched a laser-based color-change marking solution for marking cases called DataLase Casemark. The technology features the DataLase process, previously available in the DataLase Packmark solution for primary package marking. DataLase (formerly Sherwood Technologies) opened a new North American headquarters this year in Norcross, GA.

The DataLase process uses reactive coatings that change color when exposed to a low-power CO2 DataLase-approved laser. Licensed ink manufacturers incorporate DataLase’s dry-powder pigments into standard inks for sale to converters. Converters apply coating windows as packaging is produced. Data are laser marked on the packaging line, inducing a color-change reaction. Markings show up as black in color.

“Casemark is an alternative to print-and-apply case labels and case label ink-jet printing, producing a higher resolution than ink-jet,” says Kevin Murray, vice president, general manager, North America. “The converter or printer applies a white patch of ink in the marking area (a “virtual label”) and then data such as high-resolution bar codes can be written in black in the pigment using the laser. The positive image on a white background ensures that a bar code is consistently readable to a high grade—at least C and above,” he adds.

Cost savings are realized by eliminating consumables, downtime, and printhead wear. Murray says that Casemark provides 30–50% savings on a per-case basis in medium- to high-volume production.

With Packmark, a coating area is applied directly to primary packaging. “This patch can be updated at any point—even on the final packaging line—with variable data such as last-minute special offers or promotions, brand and product changes, information from a checkweigher, and customer names. You can tint the coating to any light color to blend in with the packaging graphics,” Murray says.
