Elements and Performance Criteria

  1. Confirm job specifications
  2. Set up delivery systems
  3. Select and prepare inks and additives (basic)
  4. Set up machine for basic offset lithographic printing
  5. Conduct ok 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

Setting up and adjusting MUST include EITHER:

unwind and rewind reels

webbing procedures and web control systems

splicing reels

folder and sheeter

OR

feeder and delivery

registration systems

sheet pick-up and transportation, control and transfer systems


Performance Evidence

Evidence of the ability to:

demonstrate use of control, monitoring and data entry systems

demonstrate all safety devices on the machine

set up for TWO basic lithographic printing jobs using either a wide or narrow reel or sheet-fed lithographic machine according to manufacturer’s specifications and enterprise procedures and 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:
