Elements and Performance Criteria

  1. Maintain operations of delivery systems
  2. Maintain coating process
  3. Maintain production process
  4. Identify and rectify problems
  5. Conduct shutdown of production process
  6. Clean and wash up coating machine at end of print run

Range Statement

This section specifies different work environments and conditions that may affect performance. Essential operating conditions that may be present (depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts) are included.

Delivery systems MUST include EITHER:

reel

OR

sheet

Monitoring and adjusting MUST include EITHER:

reel stand and rewind section

web control system

sheeting section

OR

feeder and delivery

sheet pick-up and transport system

transfer and control system


Performance Evidence

Evidence of the ability to:

complete THREE complex coating jobs (one spot coating, one overall coating and one fine detail, using three different coatings – one of which must be metallic, and include at least one in-line process) including:

producing a complex coated product on either a reel- or sheet-fed machine ensuring an efficient production flow maintaining product quality standards

anticipate and rectify production problems with minimum downtime

shutdown and clean the machine according to work health and safety (WHS) guidelines

use control, monitoring and data entry systems

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:

outline what to do if vital information is missing from the job ticket

outline checks to do prior to set up (availability of materials etc.)

identify major WHS concerns of:

setting up the sheet or reel transportation system

coating

For reel systems only

describe the effect:

on the print of excessive tension on the rewinding reel

if the web is not spliced correctly

outline precautions to ensure the rewound product is of consistent, acceptable quality

For sheet systems only

describe the effect of:

fanning sheets before loading into the press

anti-set off spray on finished job

explain how to set and check the double sheet detector during the print run

identify components that can be adjusted to ensure correct delivery in sheet systems

identify printed material below acceptable standard

outline what to do if the aqueous coating is smudging on the delivery section of the machine

explain the effects of :

UV lamp on the UV coating

varying temperature and volume of hot and cold air knives

using IR radiation (including choice of medium or short wave lamps) on coatings

identify the coating level to maintain in the pan

explain dangers of solvents and solutions used to clean the coating system, plates, cylinders and press

identify machine parts to be thoroughly cleaned following the coating of the job

identify components to be inspected for wear following the print run

identify records important for following or repeat prints

identify key types of information in, and the location of, machine manuals, safety and other documentation relevant to this task.
