aluminum shell and a premium chromium oxide surface with a corrosionresistant undercoang. These anilox sleeves are engraved with the latest fiber opc and solid state laser engraving equip ment to create the most prisne and consistent cell formaon, whether tradional 60 degree hexago nal or 70/75 degree extended hex for solids and flood coang. Line screens and volumes are moni tored and confirmed with either the Troika AniCam or the MicroDynamics interferometry equipment. 2) Nickleback TM Extender (NBE) Sleeve —A rubber covered nickel sleeve for plate mounng to accom modate larger repeats.

For many years, the wide web paper, film and foil industries have been moving toward the ulizaon of flexographic prinng presses ouied with anilox sleeves, air mandrels, bridge mandrels and plates mounted on plate sleeves. These sleeve sys tems allow for quicker anilox changes, decreased setup mes, varied repeat sizes and, most certain ly, eliminate the need for hoist systems to make heavy roller changes. The safety improvements alone jusfy a move in this direcon. However, many sleeve designs include the use of fiberglass in their construcon. The wound fiber inner layer of this type of sleeve construcon can break down and crack over me, rendering the sleeve unusable and in need of replacement. For every five worn or damaged fiberglass sleeves sent back for rework, it’s likely that two or three of them will need to be scrapped due to chipped ends or cracking throughout the sleeve. ARC Internaonal’s soluon to this ongoing prob lem is to use an .008” thick layer of nickel instead of fiberglass, whether it’s for the inner layer of an anilox sleeve, plate sleeve or rubbercovered sleeve. Sleeves made with a more flexible, nickel layer have a much longer product life because they eliminate that breakdown and cracking problem. In addion, nickel sleeves require significantly less air pressure for mounng and demounng, reducing the risk of injury inherent with highpressure air ap plicaons. ARC’s robust Nickelback TM Sleeve System fitment to the mandrel eliminates the need for pins and locking keyways, thus increasing the print qual ity due to beer registraon and improved run out, as well as reduced waste and setup mes. ARC’s Nickelback system includes the following products for the flexo pressroom: 1) Nickleback TM Anilox (NBA) Sleeve —A laser en graved anilox sleeve with an inner nickel layer, pro prietary bladder material for expansion, an
