Harper GraphicSolutions, the technical service arm of global anilox supplier Harper Corp. of America, has produced an illustrated guide for troubleshooting anilox roll applications. Available free upon request, the 24-page guide provides a comprehensive reference to common and not-so-common conditions that frequently arise during the anilox printing process.
Topics covered in the new guide include suggested care of bearings and gears, solutions to plate cylinder over-impressions, corrective actions for misaligned anilox, plate and impression cylinders, and cures for excessive impressions between plate and substrate. The guide also addresses ink-related issues, including monitoring of ink pressure, elimination of ink flooding and excessive pressure, avoiding improper settings of the ink roller nip, solutions to fast-drying ink, ink with excessive viscosity, water-based ink with insufficient pH, solvent imbalances and more.
