Elements and Performance Criteria
ELEMENT | PERFORMANCE CRITERIA |
1. Finger-print press | 1.1. Suitable test charts are selected or produced 1.2. Press is optimised to workplace standard, in collaboration with the press operator 1.3. Test chart is printed with standard ink densities on any one of a range of stocks |
2. Measure press test charts | 2.1. Colour measurement devices are calibrated and used to measure printed test charts 2.2. Multiple charts are measured and results recorded 2.3. Software is used to average multiple measurements |
3. Create and use custom press profiles | 3.1. Appropriate reference file is selected to match the printed chart 3.2. Profiling software is used to create an output press profile from the averaged measurement file and profile is tested and edited if required 3.3. Profile is inserted into the colour workflow |
4. Create and use digital device profiles | 4.1. Suitable test charts are selected 4.2. The device is calibrated and the test chart is output or digitised 4.3. The test chart is measured using a colour measurement device 4.4. An appropriate reference file is selected to match the test chart 4.5. Software is used to create a profile 4.6. The device profile is inserted into the colour workflow |
5. Maintain custom colour management workflow | 5.1. Printing conditions are monitored and recorded to ensure adherence to workplace standard 5.2. Digital devices are regularly calibrated |
Required Skills

Required skills |
occupational health and safety (OHS) skills for using correct ergonomics when operating the computer communication skills needed to communicate ideas and information by printing a test chart on a press planning, analysing and organising skillsto determine printing conditions and colour management requirements before generating a proof teamwork skills for maintaining the production process in association with others and working independently with responsibility for others numeracy skills used in relation to densitometry, spectrophotometry and colour profiles problem-solving skills used in diagnosing and correcting colour problems technical skills needed for utilising software and hardware correctly when creating a profile |
Required knowledge |
OHS issues to be considered when managing colour for digital production importance of bringing a device into a known state how often to calibrate devices what change of condition would result in the need for re-calibration colour measurement devices and usage types of proprietary software used for colour measurement comparison of test charts, their advantages and disadvantages process of determining grey balance and white points colour profiles and their use effect colour profiles have on output difference between input, output and display profiles colour management systems components of a colour management system components of a colour-managed workflow red, green blue (RGB) versus cyan, magenta, yellow, black (CMYK) versus mixed colour workflows how to implement colour management on a system workplace and international printing standards effects different substrates have on colour reproduction for proofing and final production how dot gain effects colour under colour removal (UCR) and grey component replacement (GCR) |
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: create custom device profiles in a digital production workflow to enhance the match across proofs, monitors and final products find and use information relevant to the task from a variety of information sources create three custom device profiles that have been used within a colour workflow produce a final printed product from the colour workflow. |
Context of and specific resources for assessment | Assessment must ensure: that conditions are typical ambient conditions found in the workplace access to relevant facilities, equipment and materials used for colour management production, such as printing presses, raster image processors (RIPs) with colour management features, profiling software, colour output devices, densitometers and spectrometers evidence of colour management system maintenance procedures use of culturally appropriate processes and techniques appropriate to the language and literacy capacity of learners and the work being performed. |
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 a portfolio that demonstrates all criteria have been met practical demonstration by the candidate in obtaining the best match across colour devices. |
Guidance information for assessment | Holistic assessment with other digital production units relevant to the workplace and job role is recommended, for example: digital production or pre-press units that require the application of colour. For valid and reliable assessment of this unit, evidence should be gathered over a period of time through a range of methods for assessment to indicate consistent performance. |
