The multi-color CI flexo machine is a high-performance central impression press built for today’s flexible packaging converters. As an advanced CI flexo printing machinery solution, it delivers precise color-to-color register on extensible films, thin papers, and laminates. Operators who need a stable and repeatable central impression flexo printing machine will benefit from the short web path, uniform drum temperature, and servo-driven deck positioning. Our CI flexographic printing machine is available with four to ten color stations and supports water-based, solvent-based, and UV inks. For high-mix, high-speed production, this CI flexo press minimizes substrate waste and reduces make-ready time through quick sleeve changeovers, automatic wash-up cycles, and real-time tension control. Ideal applications include shrink sleeve labels, stand-up pouches, lidding films, and wrap-around labels.
The Multi-color CI flexo machine is engineered around a heavy-duty cast-iron frame and a precision-ground central impression drum. The drum is double-wall jacketed with internal water circulation to keep surface temperature within ±0.5°C, which stabilizes repeat length on heat-sensitive substrates such as PE and BOPP. Each color deck uses a lightweight carbon-fiber chambered doctor blade system and a quick-change anilox sleeve with ceramic coating from 400 LPI to 1,600 LPI. All decks are rail-mounted and servo-driven, enabling automatic pre-register and closed-loop register correction through high-resolution cameras. The core advantages of the Multi-color CI flexo machine include low vibration, consistent ink transfer, and a compact footprint that saves valuable floor space in a converting plant.

The Multi-color CI flexo machine stores complete job recipes, including print pressure, drying temperature, web tension, and sleeve position. The HMI allows operators to recall a previous job within seconds and make fine adjustments without stopping the press. Pneumatic loading arms and rail-mounted deck carriages reduce sleeve changeover time to under five minutes per station. The enclosed doctor blade chamber limits ink evaporation, stabilizes pH for water-based inks, and simplifies cleaning between runs. An automatic viscosity control system adjusts solvent or water additions based on inline measurements, which keeps color density consistent from the first meter to the last. The rewind section uses taper tension control to prevent telescoping and blocking on pressure-sensitive materials. A static elimination bar, web cleaning unit, and corona treater port are integrated before the first print station to improve ink adhesion on film substrates. The electrical cabinet is separated from the printing area and rated for solvent-based ink environments, with optional ATEX compliance for explosion-proof operation. Every unit is pre-wired, factory-tested, and shipped with complete documentation, operator training, and remote technical support.
