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

Setting up and adjusting MUST include EITHER:

checking reels for treatment levels, coatings, printing side and age of product

securing reels on reel shaft

correctly positioning reels on unwind stand

positioning and mounting correctly cut cores on rewind shafts

centring and setting edge guide

setting unwind and rewind tension to suit substrate

setting nip rollers

OR

feeder

sheet pick-up and transportation system

transfer system

delivery

sheet transfer and control system

set off / marking prevention devices


Performance Evidence

Evidence of the ability to:

demonstrate all safety devices on the machine

demonstrate use of control, monitoring and data entry systems

set up a press on TWO occasions for basic flexographic printing (if possible including at least ONE in-line process), according to manufacturer’s specifications and enterprise procedures. The individual will also conduct a proof run and adjust settings to ensure production speeds are attained.

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:

ensure all required materials are available prior to set up

Flexographic printing plates and cylinders or sleeves OR plate mounting sheets

identify precautions to avoid damaging plates and cylinders

For reel systems only

Reel in-feed

explain work health and safety (WHS) factors to consider when operating the reel in-feed and delivery system

explain how to correctly select printing side of the material

Proofing and adjustment

identify methods to minimise waste during make-ready

list procedures required to have the print approved

describe quality control measurements to apply to the proof to test against known standards

outline how to check on initial print prior to running

describe how setting adjustments are determined

identify processes to plot success of the machine adjustment

describe how final results are recorded for future reference
