Elements and Performance Criteria

  1. Maintain specialised relief printing process
  2. Maintain production process
  3. Tune and adjust machinery
  4. Troubleshoot machinery and material problems
  5. Conduct shutdown of production process

Performance Evidence

Evidence of the ability to:

operate a platen, cylinder or rotary printing machine to produce a specialised printed product that maintains product quality standards, including anticipating and rectifying production problems, minimum downtime, and cleaning and shutting down the machine according to work health and safety (WHS) guidelines

access and use information relevant to the task from a variety of information sources

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

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