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 rollers and the reel or sheet systems for coating a range of carbon, carbonless, latex, wax, resin and metallic coatings, aqueous and UV varnishes and machine varnishes. 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 for THREE complex coating operations (one spot coating, one overall coating and one fine detail, using THREE different coatings of which one must be metallic) and if possible including at least ONE in-line process) according to manufacturer's 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 dedicated coating 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 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, for example: ICPPR472C Produce complex coated 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: | narrow or wide reel handling, and small and large sheet systems. |
Coatings may include: | a range of carbon, carbonless, latex, wax, resin and metallic coatings, aqueous and UV varnishes and machine varnishes. |
Machines may include: | a range of dedicated coating machines with manual, semi-automated, fully automated or computerised process control. |
Colour matching systems may include: | use of visual colour assessment and densitometry to match basic standard tints under controlled lighting conditions. |
Design may include: | spot coating, overall coating and fine detail coating. |
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. |
Substrate types may include: | full range of substrates within the major categories of paper, pressure sensitive material, board, plastics and related films, or metal. |
