Esko has officially announced the worldwide commercial availability of the XPS Spark 4835, a digital LED flexo plate exposure system designed to help label converters, tradeshops, and flexible packaging printers transition away from aging, unreliable UV tube bank exposure frames.

For years, print shops have battled with the inconsistent exposure, frequent hotspots, and unpredictable print quality caused by degrading UV tubes. The XPS Spark 4835 completely removes these headaches by introducing patented kaleidoscopic optics technology, which delivers perfectly even UVA light distribution across the entire plate surface. Because it relies on LEDs, operators no longer have to wait around for bulbs to warm up, resulting in a much faster, highly streamlined platemaking process with processing speeds that match or beat conventional systems.

Beyond boosting print quality, the system offers a massive win for sustainability and the bottom line. It cuts energy consumption by up to 80 percent compared to traditional tube bank systems. Esko achieved this by engineering a unique air-cooling setup that eliminates the need for bulky, energy-intensive chillers, alongside an insulated plate drawer that keeps heat loss to an absolute minimum.

This launch comes at a critical time for the industry. Under strict environmental regulations like EU Directive 2011/65/EU, replacement mercury-containing UVA lamps are becoming increasingly difficult and expensive to source. The XPS Spark 4835 serves as a future-ready lifesaver, positioned as an accessible, cost-effective entry point into premium LED exposure technology.

Designed to fit comfortably into any shop floor, the hardware boasts a remarkably compact footprint. Printers can also opt for an integrated UVA/UVC finishing drawer that handles back exposure, main exposure, and finishing all in a single, unified unit. True to Esko’s open philosophy, the system supports exposure parameters for all major flexo plate vendors, and upcoming dedicated screening technology will further enhance UV ink quality while dropping press make-ready times.

Early users in Germany and the US are already reaping the benefits, reporting measurable time savings and a much smoother daily workflow.

As thousands of flexo operations globally struggle to maintain aging, costly UV tube systems, the XPS Spark 4835 arrives as the ideal upgrade—delivering premium exposure quality while significantly driving down energy waste and operational costs.
