Flexo Print Sleeves, Cylinders, & Plates

In order to provide the optimum print quality, all integral shafts and cylinders to be engraved at Luminite must be received in balance. Out of balance cylinders must be balanced to Quality Grade G 2.5 at 2500 RPM prior to processing.

Patented Load-N-Lok

Un-Lok The Possibilities

Luminite has developed the first patented “Air Sleeve” system (US Patent # 8,307,764, European Patent # 2398646, Chinese Patent # ZL200980158762) that does not require an air mandrel. Our innovation means sleeves do not have to be the same length as your mandrel.

This technology, in most cases, can be used with your plant’s existing mounting system.

This new process will allow you, the printer, more flexibility than ever before. Imagine being able to run several sleeves at the same time, on the same mandrel. Possibly serving several customers at once.

Allow Luminite’s patented air sleeve system; Patented Load-N-Lok, help you take your printing to the next level by saving you time and money with millions of great impressions.

Patented Load-N-Lok Benefits

  • Sleeve length can be 1.000” longer than required print width

  • Multiple sleeves on the same mandrel

Economic Benefits

  • Reduced costs with shorter sleeves

  • Faster make-ready (set-up time)

  • Increased printing speeds

What Some People Are Saying About Patented Load-N-Lok

Our press operators have seen a 50% reduction in job set-up time. The print quality is un-matched by anything I have experienced in the past.
