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 following is essential:

correctly manufacture inks and coatings according to job specifications

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

use a mixer/disperser and EITHER a bead mill OR a 3-roll mill to manufacture TWO batches of ink/coating according to manufacturer's and job specifications, OHS requirements, enterprise procedures and the listed Performance Criteria.

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.

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/observation 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

communicating ideas and information by completing logs and checklists during manufacturing

collecting, analysing and organising information by sampling the mix to maintain quality standards

planning and organising activities by completing startup checks prior to manufacture

teamwork when completing the mix in association with fellow workers

mathematical ideas and techniques by correctly measuring materials required for the mix

problem-solving skills by anticipating production difficulties and taking preventive action

use of technology by using manufacturing and measuring equipment

Required knowledge

safety requirements for adding powders during the mixing stage of ink manufacture

OHS considerations when cleaning bowls, vats, and pots

other OHS issues that arise in the manufacture of ink or coatings

safety equipment that is required and what do you need to check when fitting and using it

batch coding system used in the work area and the recording procedures used

checks to be made when preparing containers and equipment for ink/coating manufacture

checks to be made when measuring raw materials for ink production

factors that determine the position of the mixing head

purpose of using low speed early in the mixing process

function of antioxidants in the mixing process

action taken when the mixture has a skin on it

particular requirements for coating manufacture

characteristics of the end product of the mixing phase of ink manufacture

purpose of milling ink

ideal conditions for milling ink

adjusted of the mill for low or high grind values

procedures for potting off the mill

system that is in place for labelling containers of ink

sampling and testing procedures that are used at each stage of the ink or coating manufacture process

in-process testing and how is the grind of the ink determined

checks of the ink texture and viscosity that are made during the milling process

environmental issues that need to be considered when working with the range of materials used in the manufacture of ink/coatings

manuals, safety and other documentation that are relevant to this task and where they are 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.

Materials may include:

Range of raw materials/consumables, pigment, varnish, inks, chemicals used in cleaning.

Enterprise procedures may include:

Range of enterprise procedures within defined work area as documented in enterprise procedures (SOPs).

Machines/equipment may include:

Machines/equipment may include high and low speed dispersers, mills, pan washer/scrubbers, pumps, valves, other vessels.

OHS may include:

Includes relevant legislation, regulations and enterprise policies/guidelines.

Adjustments/corrections may include:

In the range from normal operating to emergency response.

Shutdown may include:

In the range from planned shutdown to emergency response.

may include:

Liquid ink/coating manufacture and associated tasks are typically performed by operators working under limited supervision to ensure production requirements are met.

Documentation may include:

Range of work instructions including formulae, job dockets, work sheets, specifications, labels, material safety data sheets.
