List the assessment methods to be used and the context and resources required for assessment. Copy and paste the relevant sections from the evidence guide below and then re-write these in plain English.
ELEMENT | PERFORMANCE CRITERIA |
Elements describe the essential outcomes. | Performance criteria describe the performance needed to demonstrate achievement of the element. |
1. Finger-print press | 1.1 Suitable test charts are selected or produced 1.2 Press is optimised to workplace standard, in collaboration with 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 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 colour workflow |
4. Create and use digital device profiles | 4.1 Suitable test charts are selected 4.2 Device is calibrated and test chart is output or digitised 4.3 Test chart is measured using a colour measurement device 4.4 Appropriate reference file is selected to match test chart 4.5 Software is used to create a profile 4.6 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 |
Evidence of the ability to:
create custom device profiles in a digital production workflow to enhance the match across proofs, monitors and final products
identify and use information relevant to the task from a variety of information sources
complete THREE custom device profiles that have been used within a colour workflow
produce a final product from the colour workflow.
Note: If a specific volume or frequency is not stated, then evidence must be provided at least once.
To complete the unit requirements safely and effectively, the individual must:
list work health and safety (WHS) issues to be considered when managing colour for digital production
discuss importance of bringing a device into a known state
explain how often to calibrate devices
outline what condition changes result in the need for re-calibration
describe colour measurement devices and usage
list various types of proprietary software used for colour measurement
discuss comparison of test charts, their advantages and disadvantages
describe the process of determining grey balance and white points
identify colour profiles and their use
describe the effect colour profiles have on output
explain the difference between input, output and display profiles
outline various colour management systems
describe components of a colour management system
outline components of a colour-managed workflow
discuss red, green blue (RGB) versus cyan, magenta, yellow, black (CMYK), spot colour versus mixed colour workflows
describe how to implement colour management on a system
identify workplace and international publication and printing standards
explain effects different substrates have on colour reproduction for proofing and final production
describe how dot gain effects colour
discuss under colour removal (UCR) and grey component replacement (GCR).
Gather evidence to demonstrate consistent performance in conditions that are safe and replicate the workplace. Noise levels, production flow, interruptions and time variances must be typical of those experienced in the printing field of work and include access to:
printing presses
raster image processors (RIPs) with colour management features
profiling software
colour output devices
densitometers and spectrometers.
Assessors must satisfy NVR/AQTF assessor requirements.
