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!

Pre-plan the process

  1. The work area is tidied and cleaned to ensure quality of output and a safe work site
  2. The exposure and coating equipment is maintained according to manufacturer's specifications and safety requirements
  3. Exposure is controlled using step wedges and densitometry
  4. The cylinder is coated according to manufacturer's specifications
  5. The cylinder is exposed making sure image direction, autotrons and tracker lines are correctly positioned according to job specifications
  6. OHS requirements are observed when handling chemicals

Instructions to Assessors

Evidence Guide

The Evidence Guide provides advice on assessment and must be read in conjunction with the performance criteria, required skills and knowledge, range statement and the Assessment Guidelines for the Training Package.

Overview of assessment

Critical aspects for assessment and evidence required to demonstrate competency in this unit

Evidence of the ability to:

the cylinder is correctly and safely processed and etched to ensure a quality print

the underlying skills of cylinder making should be transferable across the pre-press sector. It is important that the substrate for reproduction is identified and that the quality of the cylinder be suitable for the identified printing processes

demonstrate an ability to find and use information relevant to the task from a variety of information sources

manually produce TWO gravure cylinders and establish and maintain a chemical register according to the listed Performance Criteria.

Context of and specific resources for assessment

Assessment must ensure:

assessment may take place on the job, off the job or a combination of these. Off the job assessment must be undertaken in a closely simulated workplace environment

it is expected that special purpose tools and equipment will be used where appropriate.

Method of assessment

A range of assessment methods should be used to assess practical skills and knowledge. The following examples are appropriate for this unit:

direct questioning combined with review of portfolios of evidence and third party workplace reports of on-the-job performance by the candidate.

Guidance information for assessment

Holistic assessment with other units relevant to the industry sector, workplace and job role is recommended.

Required Skills and Knowledge

Required skills

OHS in relation to operating machinery such as safely switching off machinery before cleaning is started

communication of ideas and information by interpreting the job brief

collecting, analysing and organising information by matching the job brief with production requirements

planning and organising activities by cleaning and preparing the work area

teamwork when maintaining the production process in association with others

mathematical ideas and techniques by calculating exposure and using a densitometer

problem-solving skills by recognising cylinder faults and correcting

use of technology by using equipment correctly to ensure ease of subsequent processing

Required knowledge

chemical names and symbols for three chemicals used in cylinder production

standard safety procedures used when handling gravure chemicals

two methods of manual gravure cylinder production

cylinder balancing and how is it achieved

preparation processes for both steel and aluminium cylinder bases

Blue Print and how is it produced

Direct Transfer method of cylinder production

cell depth determination

chemical of the etching solution

thickness chrome coating on the etched surface

factors that govern the rate of etch

manuals, safety and other documentation that are relevant to this task and where are they kept and information that is included in these documents

Range Statement

The range statement relates to the unit of competency as a whole. It allows for different work environments and situations that may affect performance. Bold italicised wording, if used in the performance criteria, is detailed below. Essential operating conditions that may be present with training and assessment (depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts) may also be included.

Output may include:

a variety of cylinders and shells.

Quality standards may include:

should meet client requirements and enterprise and industry standards.

Input may include:

line and tone images.

Capture may include:

carbon tissue and direct transfer methods.

Manipulation/edit may include:
