SPGPrints Enhances Laser Engraver Line

BOXMEER, THE NETHERLANDS | SPGPrints reports it has introduced quality and productivity enhancements to its flagship direct laser engraver for digitally imaging narrow web rotary screens. The new version of the rotaLEN features what is said to be an improved laser that images to high-definition (HD) standards, and an extended engraving width that accommodates wider screens and—in some cases—two meshes simultaneously.

Featuring a sealed CO2 laser that ablates the printed areas without film, chemicals or water, rotaLEN images company’s nonwoven nickel re-engravable RotaMesh and reusable RotaPlate screens with resolutions to 4,000 dpi in a single, fully digital step.

Arno Bouwmeester, managing director, SPGPrints Austria, says, “With its fully automated, simplified workflow, the rotaLEN engraver has been adopted as the standard rotary screen imaging process by several of the world’s leading label converters. It has proven capable of delivering repeatable quality consistency, significantly increased throughput and reductions in costs and emissions.”

The enhanced laser system was developed in response to demand from personal care brand owners and their suppliers seeking solutions for providing more information on a label, often in multiple languages, with optimum clarity. Company says the laser meets this requirement by engraving screens to HD quality standards and facilitating precise reproduction of fine characters, including oriental text, where accuracy is vital to legibility.

The new rotaLEN engraver accommodates RotaMesh screens up to 660 mm (26 in.) in length and a wider drum that allows two RotaPlate engraving jobs to be completed in a single engraving cycle, thereby reducing handling times and improving the efficiency of the prepress stage.

Reportedly, rotaLEN is compatible with the complete rotary screen range, from the finest meshes available, such as company’s RotaMesh 405 and RotaPlate 355F screens, to RotaMesh 75 for 250 micron-thick Braille dot reproduction. Furthermore, files processed by rotaLEN can be prepared with company’s software, reportedly providing optimum control when creating fine positive and negative images.
