Performance Evidence

Evidence of the ability to:

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

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