Keeping an eye on advances

Bill Blethen, president of Unilux, reports that stroboscopic inspection lighting, which can eliminate visual blur at speeds to 5,000 fpm, continues to evolve. Unilux recently added a series of sensors to trigger its lighting synchronously to repeats.

Converters most commonly using strobe lighting are those running labels at high-speeds with short repeats, Blethen relates. Strobe lighting can also take over after camera-based inspection of print defects to check for diecutting inconsistencies, or variations in the thickness or density of the substrate.
