Elements and Performance Criteria

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

Performance Evidence

Evidence of the ability to:

operate a reel-fed flexographic press ensuring an efficient THREE or more colour production flow that maintains product quality standards. Any production problems are anticipated and rectified with minimum downtime. The machine is correctly shut down and cleaned according to work health and safety (WHS) guidelines

demonstrate use of control, monitoring and data entry systems

monitor production output and make necessary adjustments to maintain print quality on a flexographic 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.


Knowledge Evidence
