Modification History

Release	Comments
Release 1	This version first released with ICP Printing and Graphic Arts Training Package Version 1.0.

Performance Evidence

Evidence of the ability to:

operate a lithographic press using an efficient, specialised production flow that maintains product quality standards, including rectifying production problems with minimum downtime, and cleaning and shutting down the machine according to work health and safety (WHS) guidelines

monitor production output and make necessary adjustments to maintain print quality on a lithographic machine while producing a specialised print on TWO occasions (if possible using different types and sizes of substrates) 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.

Knowledge Evidence

Assessment Conditions

Gather evidence to demonstrate consistent performance in conditions that are safe and replicate the workplace. Noise levels, production flow, interruptions and time variances must be typical of those experienced in the printing field of work and include access to:

special purpose tools, equipment and materials

lithographic printing machine with in-line units.

Assessors must satisfy NVR/AQTF assessor requirements.
