Top Quality Flexographic Machine - 4 colour CI flexo printing machine for plastic paper – Changhong

Characteristic

• The machine introduction & absorption of European technology / process manufacturing, supporting / full functional.
• After mounting the plate and registration, no longer need registration, improve yield.
• Replacing 1 set of Plate Roller (unloaded old roller, installed six new roller after tightening), only 20 Minute registration can be done by printing.
• The machine first mount plate, pre-trapping function, to be completed in advance prepress trapping in the shortest possible time.
• Maximum production machine speed up 200m/min, registration accuracy ±0.10mm.
• The overlay accuracy does not change during lifting running speed up or down.
• When machine stop, Tension can be maintained, the substrate is not deviation shift.
• The whole production line from the reel to put the finished product to achieve non-stop continuous production, maximize product yield.
• With precision structural, easy operation, easy maintenance, high degree of automation and so on, only one person can operate.
