2. Maintain in-line systems | 2.1 In-line loading is monitored, evaluated and adjusted to ensure quality of printed product meets the approved proof standard 2.2 In-line pre-treatment is monitored, evaluated and adjusted to ensure quality of printed product meets the approved proof standard 2.3 In-line drying is monitored, evaluated and adjusted to ensure quality of printed product meets the approved proof standard |
3. Maintain production process | 3.1 Production process is operated in association with fellow workers and according to enterprise procedures and planned daily schedule 3.2 Production is maintained according to work health and safety (WHS) requirements, manufacturer’s specifications and enterprise procedures 3.3 Manual and/or automatic control is used as required according to job specifications 3.4 Performance is monitored and verified using the process control system according to enterprise procedures 3.5 Ink performance, colour, register and position of print are monitored and adjusted throughout production run 3.6 Production difficulties are anticipated and preventive action is taken to prevent occurrence by timely intervention 3.7 Process adjustments to eliminate problems are reported according to enterprise procedures 3.8 Waste is sorted according to enterprise procedures |
4. Tune and adjust machinery | 4.1 Idiosyncrasies of machines are reviewed and adjustments or tuning undertaken to compensate, or to exploit the idiosyncrasy, within manufacturer’s specifications 4.2 Options are assessed to determine most effective/efficient method of production, ensuring highest quality and yield from machinery 4.3 Test run confirms correct options and settings, or need for further adjustment or tuning to meet quality standards 4.4 Options and recommendations are documented for future reference according to enterprise procedures 4.5 Instruction on new practices is provided to machine operator or finisher, if required |
5. Troubleshoot machinery and material problems | 5.1 Corrective or preventive action is recommended and implemented where appropriate 5.2 Changes are communicated to relevant personnel in a logical and easily understood manner 5.3 Changes are monitored to confirm improvement to production efficiency 5.4 Ongoing problems are reported according to enterprise procedures |
6. Conduct shutdown of production process | 6.1 Correct shutdown sequence is followed according to manufacturer’s specifications and enterprise procedures 6.2 Shutdown is conducted in association with fellow workers and in compliance with WHS requirements 6.3 Unused ink is correctly labelled and stored according to manufacturer’s/supplier’s specifications and enterprise procedures 6.4 Solid and liquid waste is removed from operating area and recycled or disposed of, where required, according to regulatory requirements and enterprise procedures 6.5 All product is removed from operating area 6.6 Machine faults requiring repair are identified and reported, according to enterprise procedures 6.7 Repair/adjustment is verified prior to resumption of operations |
Evidence of the ability to:
operate a pad printing machine ensuring an efficient specialised production flow that maintains product quality standards, including rectifying production problems with minimum downtime, and shutting down and cleaning the machine according to work health and safety (WHS) guidelines
produce TWO complex pad printing jobs (if possible on different substrates) according to job specifications, enterprise procedures and performance criteria.
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:
identify major WHS concerns when operating this machine
locate where Material Safety Data Sheets (MSDS)s are stored and describe the information they contain
explain how colour density of a light image on a dark substrate can be improved by selecting a different machine cycle mode
explain how to select appropriate machine cycle mode to provide the highest production output for a particular product
describe special cycle modes available on the machine and their application
describe how to determine that ink has been mixed to the correct viscosity
explain how to correct ink viscosity during production
list causes of unreleased ink remaining on the printing pad, and how to identify them
describe the effect of adding a catalyst on the pot life of ink and other factors that affect pot life
explain how to recognise a damaged pad
demonstrate the correct method of cleaning a pad during production
describe the effect of different pad shapes for different colours In multi-coloured printing
determine the time ink should take to cure before scratch and adhesion tests can be performed
describe the method used to check for correct pre-treatment of polypropylene during production
explain how to ensure correct drying conditions for the product
describe the visible effects on the image if ink viscosity is incorrect
identify the cause of incorrect registration and how to prevent its recurrence
explain what can cause a fine coating of ink over the whole cliché surface
locate machine manuals, safety and other documentation relevant to this task, and outline the information in them.
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 special purpose tools, equipment and materials, including a pad printing machine.
Assessors must satisfy NVR/AQTF assessor requirements.
