Miraclon, in partnership with US-based trade shop, SGX, has concluded a recent study that confirms the Shine LED Lamp Kit produces high-quality plates that provide measurable benefits for a full range of LAMS flexo plates over fluorescent exposure. The results from the collaboration, which included comprehensive testing of five different LAMS plate types, have been published in a technical paper.
“Many platemakers have been asking whether Shine LED Lamps could deliver the benefits of LED exposure beyond FLEXCEL NX Plates,” said John Prindl, Director of Global Product Support, Miraclon. “This study proves that these lamps not only work but excel; offering faster exposure, improved uniformity, and better dot reproduction across a wide range of LAMS plates.”
The LAMS flexo plates tested included both round-top and flat-top dot configurations, plus a thicker plate for corrugated printing. Using four identical exposure frames, two fitted with traditional fluorescent bulbs and two with Shine LED lamps, the study results demonstrated that Shine LED lamps delivered:
- Up to 5x faster exposure times (combined back and main exposure);
- 2x better plate floor uniformity;
- Sharper, more consistent highlight dots and tonal transitions;
- Stable light output, eliminating the degradation issues common with fluorescent bulbs.
Subsequent print trials demonstrated that plates exposed with Shine LED lamps matched or exceeded the print quality delivered by fluorescent-exposed plates. Notably, round-top dot plates showed a significant improvement in dot shape and consistency — a key factor for smooth highlights and tonal control.
Unlike fluorescent bulbs that degrade over time — leading to inconsistent exposure and eventual replacement — Shine LED lamps provide consistent UV output, reducing waste, downtime, and plate reworks. The lamp kit installs easily into existing fluorescent exposure frames, providing a low-barrier upgrade for trade shops and packaging printers alike, and can be retrofitted in the field in a few hours.
For a fraction of the cost of a new LED exposure unit, users benefit from consistent, predictable intensity over a much longer operating life (more than 5,000 hours compared to 800 hours for fluorescent tubes), faster exposures, and enhanced sustainability performance.
