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:

should meet client requirements and enterprise and industry standards

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

prepare at least TWO different lots of ink and additives that require special colour matching and match colour sample by manual and electronic means to job specification, industry standards and listed performance criteria. Ideally each lot of ink should be a different type for use on a different substrate

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

inks and additives.

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

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

communication of ideas and information by correctly labelling inks and additives

process for recording the recipe for the colour

labelling mixed inks systems

environmental conditions that are in place for the storage of inks

keeping manufacturer's specifications and MSDSs

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

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.

Type of ink, substrate may include:

ink and substrates used for special inks used in printing processes relative to industry sectors.

Quality standards may include:

should meet client requirements and enterprise and industry standards.

Type of equipment may include:

manual and electronic measuring equipment.

Colour matching systems may include:

colour matching systems commonly used in the industry.

Enterprise procedures may include:

range of enterprise procedures within defined work area.
