3 * Simple proven process * Quick make-ready * low speed sensitivity * low impression sensitivity * variable ink film (better fidelity) * consistent long runs * Cylinders expensive * Cylinders take time to make PLUS MINUS ENGRAVED CYLINDER IMPRESSION ROLL DOCTOR BLADE WEB INK Rotogravure
4 WEB BLANKET CYLINDER PLATE CYLINDER DAMPING TRAIN INK TRAIN IMPRESSION CYLINDER INK DUCT * Proven process * Highest quality process print * High manning * High skill level needed * Color control issues * Not in line with die cutting etc. PLUS MINUS Lithography
5 MINUS * Low cost presses * In line capability * Quick make-ready * Less manning/skill level * Consistent color * Process print quality * Variable industry capability PLUS WEB PLATE IMPRESSION ROLL ENCLOSED INK CHAMBER ANILOX Flexography
6 2. Composition and Chemistry - Oil base - Solvent Base - Water Base - Radiation Cure 1.Physical Form - Liquid - Paste Ink Types
7 TYPICAL PROPERTIES Viscosity 50-100 centipoise Solids 35% Tack Very low Drying Absorption/evaporation Trap Wet on dry Cure Immediate VOC < 1% by wt. Odor Very low Cost OK FLEXO GRAVURE Ink Formulation – Water Base
OFFSET PROOFING Blanket roller picks up ink from plateTransfers it to substrate Plate Substrate Plate is inked up by a hand roller Difficult to accurately control ink film thickness from hand roller to plate. This will cause some variation when transfering to substrate.
