Elements and Performance Criteria

  1. Maintain non-routine operation of reel transportation system
  2. Maintain non-routine operation of reel delivery system
  3. Maintain complex gravure printing process
  4. Maintain operation of in-line processes
  5. Maintain non-routine production process
  6. Identify and rectify faults
  7. Conduct shutdown of production process
  8. Clean and wash up printing machine at end of print run

Performance Evidence

Evidence of the ability to:

operate a gravure press ensuring an efficient non-routine production flow that maintains product quality standards; any production problems are rectified with minimum downtime; and the machine is correctly shut down and cleaned according to work health and safety (WHS) guidelines

monitor production output and make necessary adjustments to maintain print quality on a gravure machine while producing a complex print on TWO occasions (if possible using different substrates and, if possible, including at least two in-line processes) according to job specifications and enterprise procedures.

Note: If a specific volume or frequency is not stated, then evidence must be provided at least once.
