6 Colour Rotary Web Offset Printing Machine For Color Box Packaging Printing

Color box packaging: wine box, medicine box, cosmetic box, cake box
Corrugated box: small home appliance box, high-end shoe box, gift box
Label category: oil drum label bucket label oil label clothing tag
Film-based printing: PVC film base
suitable materials:
self-adhisive paper/pvc/pet/opp,polyster film,laminate tubes,flexible packaging material,etc



A) Electric Control System: The main control unit adopts imported electric components, together with CPU via DOS system to control the servo motors, which ensures the machine, high responding, accurate towing, easy operating and safe running.
B) Shaftless Driving: The machine uses servo motor to drive the rollers directly, providing a guarantee for precise high-speed running.
C) Overprinting System: Once printing length is input at the main control unit, every unit will move automatically to the preset position. Each unit is controlled individually by a motor. With the help of CCD image, lateral, longitudinal and bevel direction registration can be achieved without stopping the machine production. This greatly increases the print quality and reduced the production wastage.
D) Printing Unit: Each unit can work independently, which enhance the production efficiency greatly. There is a touch screen on each unit, you can work easily.
E) Water And Ink Control: The machine adopts advanced American water and ink supplying system which ensures the water and ink balance, stability at low and high speed and bright print result. The classic structure, which makes the water and ink perfect mixture and balance on the first printing roller through one bridge roller, greatly reduced the waste of the material. The floating print roller, which is firstly used in China, effectively prevent the ink bar and ghost from the print. Film and paper can be printed on this machine easily.
F) Vacuum Unwinding Device (patented, This is optional. If client do not choose this function we can do roller unwinding system as well): The suction pulling device keeps the tension stable and prevents scratch and napping caused by the friction generated among several parts and printing material. Full version can be printed without blank, which also greatly expands the scope of materials application
G) Lubricating System: The machine uses automatically cycling oil-supply system to ensure the accuracy and service life of the machine.
H) The computer controlled automatic and manual plate mounting and dismounting system shortened the plate changing time and increases the safety level of the machine. ( Plate changing for 6 color only needs 6 minutes)
I) The Japanese origin SMC Pneumatic clutch pressure control system ensures smooth and accurate running of the machine; Twice clutching done by Japanese Fujikoshi three point suspension bearing, makes the PS plate and the water blanket fully pre-inked and then be pressed which greatly reduces the pre-print paper wastage.
J) 7 o'clock arrangement of the rollers, high precision servo drive, twice clutching control and color lose prevention system make high quality prints and competitiveness of the machine.
K) Heidelberg ink fountain partition structure, easier to adjust the ink, reducing printing time and paper waste.
L) This machine can also be equipped with automatic registration system, automatic ink volume control system, flexo press unit, letter press unit, varnishing unit and rotary die-cutter unit, to enable multifunction of the machine and to improve marketing competitiveness.
