Harper seminars focus on sleeve care
Anilox supplier Harper Corporation of America, of Charlotte, NC, USA, has created an educational program about anilox sleeves, which it has presented to customers at its headquarters and also at its plant in Green Bay, WI, USA. The seminars have been created by Harper GraphicSolutions (HGS), the technical service arm of the company.
The program began as a 24-slide presentation created by Bill Poulson, HGS Northeast technical representative, and Tony Donato, process and product development engineer. It has evolved to almost 70 slides and a table full of training aids. Spearheaded by Alan Rogers, HGS Southeast Technical Account Manager and David Watson, HGS Southeast technical service representative, the “Anilox Sleeve Presentation” has expanded into a full day of training, including an expanded question-and-answer session for customers’ specific problems.
According to Rogers, “There’s a need for training on anilox sleeves because the care and maintenance of sleeved anilox rolls differs from journaled anilox rolls. The majority of new wide web presses and an ever-growing number of narrow and midweb presses installed today are sleeved presses, so it’s critical that our customers are informed of the differences.”
The seminar reviews basic sleeve construction, and how it differs from that of conventional journaled anilox rollers. Because sleeves are easily mounted and changed, the impact of cumulative total indicator readings between the press mandrel and anilox sleeve is explained and demonstrated. The re-engravability differences between rolls and sleeves are examined in detail. Speakers cover the specifics of proper sleeve handling, storage and cleaning in great detail, reviewing photos of damaged and destroyed sleeves, and focusing on how to avoid such damage.
