In-depth Testing
Vibration Analysis
Excessive vibration will reduce print quality and increase
component wear
An Accelerometer was used to measure the vibration of the
Decorator in different directions, and at different speeds

Result was a redesign of the Spindle disc cam profile
which resulted in a significant improvement over the
previous

In-depth Testing
Print Quality Assessment
Use of Finger Print test to remove ambiguity
Uses a special plate with a known dot size
Tested at two different speeds and two ink colours
Compared print consistency at different inker positions
Result is that the distribution of Dot Gain is better than
our targeted range

In-depth Testing
Ink Temperature
Ink temperature is affected by the ambient temperature and
the heat generated by friction between the rollers, which
increases with speed
Managed by 5 water cooled rollers in each Inker
Ink temperature can be controlled by adjusting the
temperature and flow rate of the coolant
Ink temperature affects the viscosity or “tackiness” of the ink,
which in turn affects the final print
Therefore more consistent temperature = more consistent
print quality
Original configuration Inconsistent Response to Inconsistent shapes → changes in speed and flow
Wide range of colours → Wide range of temperatures
Result was a reconfiguration of the cooling hose layout
and an increase in flow rate, which improved response
to changes in speed and flow and reduced range of
temperatures.

Next Steps
Production Testing
Prove out the machine in a production environment
Ensure the machine is robust enough in production
To produce quality printed cans at speed and consistently
To prove quick change features
Fully develop training material
