High-quality graphic reproduction on extensible plastic films requires strict web tension and registration control. Central Impression (CI) technology locks the substrate against a single central cylinder, eliminating print misalignment.
Why CI Drum Technology Prevents Registration Errors
In stack presses, the film travels unsupported between each color deck, resulting in material stretch and misregistration on thin LDPE/BOPP films. In CI presses like our AI-6C and AI-8C series, the film is anchored to a precision central steel cylinder, locking color-to-color registration within ±0.1mm even at speeds of 260–350 m/min.
