Elements and Performance Criteria

  1. Confirm job specifications
  2. Set up delivery systems
  3. Select and prepare coating
  4. Set up machine for coating
  5. Conduct proof 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:

unwind and rewind reels

web control system

print web viewing devices

set off / marking prevention devices

OR

feeder and delivery

sheet pick up and transportation system

transfer and control systems

set off / marking prevention devices


Performance Evidence

Evidence of the ability to:

set up rollers and reel or sheet systems for coating a range of aqueous coatings, UV varnishes and machine varnishes and conduct a proof run and adjust settings to ensure production speeds are attained

demonstrate use of control, monitoring and data entry systems

demonstrate all safety devices on the machine

set up for TWO basic coating operations (one spot coating and one overall coating and, if possible, including at least one in-line process) according to manufacturer’s and job specifications, and enterprise procedures.

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:

Interpret job specifications

identify where information about the type of required coating is located on the work ticket

explain actions to be taken if vital information is missing from the job ticket

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

For reel systems only

list major work health and safety (WHS) concerns when setting up the reel transportation system

outline safety risks associated with the machine’s rewind section

explain how low web tension and inefficient web splices impacts the print

identify how the machine recognises if there has been a web break

describe effect of excessive web tension at the rewind section of the machine

discuss how to determine reel position for the job

For sheet systems only

list major WHS concerns when setting up the sheet transportation system

discuss how to determine sheet position for the job

explain how appropriate front lays are selected

list reasons for a two-sheet cut-out on most feeders

identify how the machine recognises if a sheet is missing or late

identify how the coating side of the material is chosen

identify why a register check is carried out

Delivery system

identify impact of too much vacuum on slow-down wheels has on the job

describe what determines position of register or bustle wheels

outline impact of excessive jogging on the stack

Coating preparation

list WHS concerns relevant to use of coatings

list THREE types of coating

describe how suitability of coating for the job is determined

outline how ability of the coat to adhere to the product is determined

explain how to determine how much coating is required

describe range of viscosities to be run with on aqueous coatings

outline the impact of incorrect viscosity

explain how to adjust viscosity of a coating

Machine set-up

explain methods the coating uses to solidify

explain what is required to dry UV coating

explain printing principles used to apply aqueous coating

describe what temperature the drier should be set at to dry aqueous coating

outline how to determine which image carrier (plate or blanket) to use

Proofing and adjustments

describe how position of the coating is checked against the print

discuss the impact skeleton wheels have on the coating surface

outline how the amount of gloss on the surface can be measured

identify who is responsible for the final OK on the job

describe the impact of not enough coating on a sheet

describe the impact a UV coating has on a wet print
