Elements and Performance Criteria

1. Confirm specialised job specifications
   • Job requirements are read and interpreted from job documentation or production control system
   • Availability of all job related components is checked
2. Plan and carry out specialised set-up
   • Specialised job specifications are identified and analysed
   • Specialised set-up requirements are determined
   • Specialised set-up is completed in minimum time with minimum wastage
   • Appropriate tampons are selected according to job specifications
   • Tampons are secured into machine
3. Conduct specialised set-up of fixtures onto machine bed or conveyor
   • Appropriate fixtures are selected and secured to xy table or conveyor jig plates
   • Height of machine bed is adjusted to suit size of object to be printed
   • Xy table of machine bed is adjusted to suit position of image on object
4. Select and prepare inks and additives
   • Inks and additives are evaluated according to job specifications
   • Inks and additives are selected according to job specifications
   • Inks and additives are prepared according to work health and safety (WHS) requirements and manufacturer’s/supplier’s instructions with suitable precautions to minimise waste
   • Correct colour and weight/volume of ink are mixed and prepared according to requirements of the printing process and job specifications
   • Formulation of ink, colour match and approved colour are appropriately recorded
   • Inks and additives are appropriately labelled, handled and stored according to manufacturer’s/supplier’s instructions to prevent damage and hazards to personnel and to prolong shelf life
5. Set up machine for specialised pad printing
   • Plate holders are set up and adjusted for register according to job specifications
   • Appropriate plates and plate holders are selected and plates are secured into plate holders
   • Tampons are set up, evaluated and adjusted according to job specifications
   • Spatula and doctor blade are set up, evaluated and adjusted according to requirements of the pad printing process and job specifications
6. OR
   • Ink cups are set up, evaluated and adjusted according to job specifications
7. Set up pre- and post-treatment processes
   • In-line loading is set up according to specialised object requirements and job specifications
   • In-line drying is set up according to specialised object requirements and job specifications
   • In-line ejection is set up according to specialised object requirements and job specifications
8. Conduct specialised proof run
   • Material to be used for proof is organised correctly
   • Machine is operated according to manufacturer’s specifications and enterprise procedures to produce a specified proof
   • Proof is visually inspected and/or tested or laboratory testing is organised according to enterprise procedures
   • Production does not commence without client approval or authority where appropriate
   • Results are interpreted and evaluated with adjustments carried out according to product and machine specifications
9. Troubleshoot machinery and material problems
   • Corrective or preventive action is recommended and implemented where appropriate
   • Changes are communicated to relevant personnel in a logical and easily understood manner
   • Changes are monitored to confirm improvement to production efficiency
   • Ongoing problems are reported according to enterprise procedures

Performance Evidence

Evidence of the ability to:

safely set up a machine for specialised pad printing on TWO occasions, on different substrates, to meet manufacturer’s and job specifications, enterprise procedures and the performance criteria

set up manual pre- and post-treatment processes and conduct a proof run including adjusting settings to ensure production speeds are attained

find and use information relevant to the task from a variety of information sources.

Note: If a specific volume or frequency is not stated, then evidence must be provided at least once.

Knowledge Evidence

To complete the unit requirements safely and effectively, the individual must:

identify FOUR different substrate groups and suggest correct ink type for each group

explain THREE possible sub-groups of plastic in relation to ink selection

explain how to adjust process colour inks for correct colour balance

describe TWO methods of improving opacity of a light coloured ink on a dark substrate

outline how to determine correct pad shape for the FOUR applications

explain the effect that pad shape and hardness have on print quality

describe the effect commonly seen at the contact point of the nipple of a pad in a large solid print and how can it be avoided

outline how to prepare a new pad before its first printing

describe the correct plate type for these (given) applications

explain the difference between steel and photopolymer plates for process printing

discuss reasons for mis-registered images, and how they can be corrected

list work health and safety (WHS) concerns of setting presses and doctor blades

discuss possible machine adjustments so the doctor blade operates correctly

describe the effect of a damaged doctor blade

list various types of doctor blades and explain their applications

list WHS concerns when using pre- and post-treating substrates

outline common pre- and post-treatment methods for different substrates

explain the importance of pre- and post-treatments for different substrates

list causes and solutions for SIX common print problems (eg hairlines around image, loss of density in the centre of a solid image, fine lines of ink running through image, distortion of image, picking up ink from substrate by subsequent pads, washed out images, loss of fine lines in images, inconsistent colour)

identify where machine manuals, safety and other documentation relevant to this task are kept, and describe the information in them.
