Tips for gathering evidence to demonstrate your skills

The important thing to remember when gathering evidence is that the more evidence the better - that is, the more evidence you gather to demonstrate your skills, the more confident an assessor can be that you have learned the skills not just at one point in time, but are continuing to apply and develop those skills (as opposed to just learning for the test!). Furthermore, one piece of evidence that you collect will not usualy demonstrate all the required criteria for a unit of competency, whereas multiple overlapping pieces of evidence will usually do the trick!

Evidence of the ability to:

produce TWO photopolymer plates with different characteristics according to the listed performance criteria

transfer underlying skills of plate making across the design and pre-press sectors (it is important the substrate for reproduction is identified and the quality of the plate is fit for the identified printing processes)

correctly prepare plate to meet the job brief and manufacturer’s specifications

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

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

To complete the unit requirements safely and effectively, the individual must:

explain effect screen dot has on the printing process

outline work health and safety (WHS) requirements for photopolymer plate chemicals

explain how to overcome undercutting of screens

outline methods to counteract air entrapments between film and plate

list manuals, safety and other documentation relevant to this task and identify where are they kept and what information is included.
