Modification History

Release	Comments
Release 1	This version first released with ICP Printing and Graphic Arts Training Package Version 1.0.

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:

Interpreting job specifications

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

explain checks to be done prior to set-up e.g. availability of materials

Preparing and fitting plates

list problems that can result if the cylinder is not cleaned prior to plate fitting

explain how the grip edge of the plate is identified

describe the effect of over packing the printing plate cylinder

discuss how pitch lines can be used to assist in plate installation

name tools or actions likely to damage the plate

explain why plates should be consistently tensioned

For reel systems only

Reel in-feed

identify work health and safety (WHS) precautions for webbing up the machine

discuss how to determine the printing side of the material

explain the effect of low web tension on the print

explain the purpose of nip rollers

identify types of web splices appropriate for the job

Reel delivery system

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

list risks associated with the rewind of the machine

For sheet systems only

Sheet in-feed and transfer

identify WHS factors to be considered when setting up sheet in-feed and transfer systems

explain why the sheet is normally set up in the middle of the machine

describe the effect of side lay selection on the job

explain how to determine the position of the sheet before it is transported to the printing unit

outline how a register check is carried out

describe why a two-sheet cut is used on most feeders

explain how the machine knows if a sheet is missing or late

explain why the application of spray powder is sometimes advisable

explain the effects of too much spray powder

explain why slowdown devices might be used in delivery

outline the effect of excessive jogging on the stack

Preparation of inks and additives

identify all WHS and environmental concerns associated with inks and additives

explain what details to check for suitability of an ink for a job

describe how to modify ink that is slightly light

outline methods available to check ink for correct colour

identify who passes the colour prior to running the job

Machine set-up

list all work health and safety (WHS) factors to consider when setting up the machine

explain how cylinder (plate, blanket and impression) specifications are determined for the specific job

explain effects an incorrectly set dampening system may have on the job

explain why ink profile varies across the machine

explain what optimum ink duct sweep is

Basic in-line processes

explain the correct machine position to engage in-line processing units

list essential precautions required when setting up in-line processing units

outline necessary precautions if UV drying is utilised to dry the ink film

Proofing and adjustment

identify methods to minimise waste during make ready

describe what to check on the initial print prior to running

explain how the machine is proof tested

outline ideal conditions for inspecting the proof

describe methods to check and adjust ink colour and consistency

identify adjustments that may cause mis-register

list adjustments to position the image laterally

identify adjustments to position the image circumferentially

identify who has the final say in the approval of the job

Information sources

identify machine manuals, safety and other documentation relevant to this task, where are they kept and the information contained.

Assessment Conditions

Gather evidence to demonstrate consistent performance in conditions that are safe and replicate the workplace. Noise levels, production flow, interruptions and time variances must be typical of those experienced in the printing field of work and include access to:

special purpose tools, equipment and materials

lithographic machine.

Assessment processes and techniques must be able to be modified for distance-based learners and be culturally appropriate and suitable to the communication skill level, language, literacy and numeracy capacity of the candidate and the work being performed.

Additional support may be needed for the Indigenous community and others from a non-English speaking background.

Where applicable, physical resources should include equipment modified for people with special needs as well as assistance to support their participation in the assessment process.

Assessors must satisfy NVR/AQTF assessor requirements.
