Evidence Required

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

set up reel or sheetfed platen cylinder or rotary printing machines for nonroutine print jobs The individual will conduct a proof run and adjust settings to ensure production speeds are attained

demonstrate use of computerised control monitoring and data entry systems if available and appropriate

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

set up a relief printing machine for complex printing on TWO occasions if possible using different substrates and if possible including at least TWO inline processes according to manufacturers and job specifications enterprise procedures and the Performance Criteria

evidence for assessment may be gathered from assessment of the unit of competency alone or through an integrated assessment activity

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

reel or sheetfed platen cylinder or rotary printing machine

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 onthejob performance by the candidate

Guidance information for assessment

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

ICPPRC Produce complex relief printed product

ICPPR352C Produce complex relief printed product.

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.

Substrate handling may include:

wide and narrow reel, and large and small sheet handling systems.

Inks/coatings may include:

range of inks commonly used in 3 or more colour printing, including standard and special colours.

Colour matching systems may include:

use of densitometers and spectrophotometry.

Machines may include:

range of platen, cylinder and rotary machines with manual, semi-automated, fully automated or computerised process control.

Design may include:

3 or more colours, complex graphics and text. Critical "tight" registration, fit and position, registration should be at least that required for four-colour process work.

In-line processes may include:

minor processes that are integral to this competency can include basic in-line operations such as perforating, numbering, date coding, slitting that do not in themselves constitute another defined unit of competency. Where a major in-line process is defined as a separate competency (eg flat-bed cutting, folding) it should be assessed as such.

Substratetypes may include:

range of substrates within the major categories of paper, pressure sensitive material, board, plastics and related films, or metal.

Non-routine may include:

non-routine within this context relates to the set up and production of print runs. The set up of equipment and production involves a significant amount of deviation from using standard equipment settings. It also involves significant problem solving and the development of new criteria and procedures for performing current practices. It does not refer to a job that an individual does only occasionally.
