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:

prepare and mount flexographic plates and plate cylinders for complex printing to meet job specifications, including checking registration if necessary

mount and demount plates and install in a flexographic printing machine for a variety of different complex print jobs on TWO occasions according to job specifications.

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:

list work health and safety (WHS) concerns of mounting and demounting plates

describe the most common cause of photopolymer plates crazing on the image side

explain the importance of printing plate resiliency

list the main advantage of using thin photopolymer plates in process printing

outline faults that may be detected on new plates

identify type of solvents used on photopolymer plates

describe benefits of optical mounting

explain the purpose of binding plates after mounting

outline possible print faults that could be eliminated by using cushion mount

describe the result of air being trapped under plates

explain how to eliminate low spots

explain how to minimise press bounce in jobs that are mounted more than one across

list some possible causes of print slur

explain how to prevent or minimise plate lifting

explain the method used to make registering the job easier on the press
