Product Overview

Discovery Call

Uniform exposure, smaller footprint.

XPS Spark is engineered for uniform, repeatable exposure using full-surface UVA LED technology and patented Kaleidoscope optics. Its air-cooling system stabilizes temperature for consistent UV output, while the thermally isolated plate drawer prevents heat buildup during exposure. The result: stable polymerization, consistent relief, and reliable print quality from plate to plate.

Why Switch Now

Exposure drifts over time
Harder-to-source mercury lamps
Inconsistent output

What Makes it Different

Edge to edge uniformity. Patented Kaleidoscope optics deliver perfectly even exposure across the plate.
Instant on productivity. Full-surface LED exposure with no warm-up time or exposure drift.
