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 either wide or narrow reel or sheetfed lithographic printing machines for specialised print jobs The individual will conduct a proof run and adjust settings to ensure production speeds are attained in minimum time with minimum wastage

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 lithographic printing machine for a specialised job on TWO occasions if possible using different substrates and sheet sizes if sheetfed 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

lithographic 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
