Drukken - ETIKETTENDRUK OFFSET - VIVA 420
The VIVA 420 is one of the most productive intermittent-feed presses on the market. The press uses the advantages of the intermittent for short make ready combined with a larger print width and higher speed to answer needs on long runs.
The VIVA 420 is fully-servo-driven press, so that many features can be automated, and optimizes all set-up operation.
The VIVA 420 combines the advantages of intermittent feed technologies with the productivity of rotary presses:
Format changes
Format changes are performed without changing any cylinders. Printing plates are mounted quickly onto the press without any tooling.
Changes are entirely electronic. The pre-register position is displayed on every unit depending on format. Unit positioning is motorized and controlled locally or from the central control panel. Pre-positioning is done at press stop without waste.
Productivity
As an example, for a repeat length close to 325mm (13"), the VIVA420 allows a production speed up to 60m/min (180fpm) i.e. a production capacity of 1500m2 (2350 msi/h) thanks to the web width of 420mm (16" ½).
Servo Technology
The VIVA 420 uses the last generation of servo control developed by B&R Automation. The machine is built around a simple architecture with independent print unit communicating through a high speed bus. This network system allows a higher flexibility and an access to all the system components, making diagnosis much simpler.
Advantages are:

The VIVA 420 combines the advantages of intermittent feed technologies with the productivity of rotary presses:
- With a 420mm width, a 19'' print cylinder base, and speeds up to 12000 imp/h in intermittent mode the VIVA420 is the most productive intermittent press.
- Without format depending tools the adjustments to go from one job to another are minimal and therefore set up time and waste are minimized.

This network system allows a higher flexibility and an access to all the system components, making diagnosis much simpler.
Advantages are:
- independent control of each print unit for an optimum flexibility.
- register and print quality is improved.
- communication bus allows access to all press basics press functions like register or fountain roller speed locally
or remotely from the main control touch-screen panel. - control panel uses a touch screen with intuitive interface to ease press operation.
- the operator interface includes wide monitoring and diagnosis functions as well as modem connection for remote diagnosis.
