Elements and Performance Criteria

Required Skills

This describes the essential skills and knowledge and their level required for this unit

Required skills

This competency requires the skills of

interpolation and extrapolation of data

Required knowledge

Competence includes an understanding of colour and how the pigments used interact with the process to develop the required colour in the final product In particular it includes the ability to

recognise hue value and chroma or colourtone lightnessshade and saturation differences

describe the effect of a change of light conditions on the appearance of the colour for the pigment combination used as relevant to the product

recognise colourant addition and colourant dispersion differences

make judgements based on

acceptabilitytolerance

grade or match as required by specification

describe the impact of opacity on colour as relevant to the product

Evidence Required

The Evidence Guide provides advice on assessment and must be read in conjunction with the Performance Criteria Required Skills and Knowledge the Range Statement and the Assessment Guidelines for the Training Package

Overview of assessment

Assessment of this unit should include demonstrated competence on actual plant and equipment in a work environment The unit will be assessed in as holistic a manner as is practical and may be integrated with the assessment of other relevant units of competency Assessment will occur over a range of situations which will include disruptions to normal smooth operation

Simulation may be required to allow for assessment of parts of this unit Simulation should be based on the actual plant and will include walkthroughs of the relevant competency components Simulations may also include the use of case studiesscenarios and role plays

This unit of competency requires a significant body of knowledge which will be assessed through questioning and the use of whatif scenarios both on the plant during demonstration of normal operations and walkthroughs of abnormal operations and off the plant

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

Competence must be demonstrated in the ability to recognise and analyse potential situations requiring action and then in implementing appropriate corrective action

The emphasis should be on the ability to stay out of trouble rather than on recovery from a disaster

Consistent performance should be demonstrated In particular look to see that

estimates of required adjustments are consistent with the colour match data

adjustments are made cautiously and without overshooting

adjustments are made efficiently with a minimum number of adjustments to bring the batch into specification

These aspects may be assessed using a range of scenarioscase studieswhatifs as the stimulus with a walk through forming part of the response These assessment activities should include a range of problems including new unusual and improbable situations which may have been generated from the past incident history of the plant

Context of and specific resources for assessment

Assessment will require access to an operating plant over an extended period of time or a suitable method of gathering evidence of operating ability over a range of situations A bank of scenarioscase studieswhatifs will be required as will a bank of questions which will be used to probe the reasoning behind the observable actions

Method of assessment

In all plants it may be appropriate to assess this unit concurrently with relevant teamwork and communication units

Guidance information for assessment

Assessment processes and techniques must be culturally appropriate and appropriate to the oracy language and literacy capacity of the assessee and the work being performed

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. Add any essential operating conditions that may be present with training and assessment depending on the work situation, needs if the candidate, accessibility of the item, and local industry and regional contexts.

Codes of practice/ standards

Where reference is made to industry codes of practice, and/or Australian/international standards, the latest version must be used.

Context

This unit of competency includes the use of items of equipment required for colour sample preparation and colour matching.

Sample properties may include:

substrate properties.

Sample preparation methods may include:

Sample preparation conditions may include:

Colourants may include:

Health, safety and environment (HSE)

All operations to which this unit applies are subject to stringent health, safety and environment requirements, which may be imposed through State or Federal legislation, and these must not be compromised at any time. Where there is an apparent conflict between Performance Criteria and HSE requirements, the HSE requirements take precedence.
