As an early adopter of XPS Spark 4835, Nagels Druck evaluated the system under real production conditions while looking to move beyond aging exposure technology. From day one, the team observed improvements in screen reproduction, sharper image detail, color consistency, and overall repeatability.
For Nagels Druck, the evaluation wasn’t about adopting new technology for its own sake. It was about strengthening the foundation of the flexographic process and ensuring today’s quality standards can be maintained tomorrow. As the team discovered, sometimes one test plate really is enough to reveal what’s possible.
The Challenge
Like many flexo printers, Nagels Druck was relying on exposure technology that had delivered reliable results for years. But as customer expectations continued to rise, the team began looking for ways to further improve consistency, repeatability, and overall print quality across their flexographic workflow.
The Solution
Nagels evaluated the Esko XPS Spark 4835, a compact full-surface UVA LED exposure system designed to deliver highly controlled, repeatable plate exposure while reducing the maintenance challenges associated with traditional tube-based systems.
The Benefits
- Improved screen reproduction and image quality
- Better color consistency across print runs
- More repeatable plate production results
- Reduced variability throughout the flexographic process
- A modern LED-based alternative to traditional exposure technology
