The Evidence Guide provides advice on assessment and must be read in conjunction with the performance criteria, required skills and knowledge, range statement and the Assessment Guidelines for the Training Package.

Overview of assessment

Critical aspects for assessment and evidence required to demonstrate competency in this unit

Evidence of the ability to:

managing colour in pre-press operations to ensure that proofs, monitors and final products match

demonstrate an ability to find and use information relevant to the task from a variety of information sources

a portfolio that demonstrates all criteria have been met. This should include evidence of THREE jobs with final product printed on various stocks and matching digital proofs on simulated stock. Monitors should also be checked to ensure that they have different loaded profiles that match jobs. There should also be evidence of colour management system maintenance procedures.

Context of and specific resources for assessment

Assessment must ensure:

assessment may take place on the job, off the job or a combination of these. Off the job assessment must be undertaken in a closely simulated workplace environment.

Method of assessment

A range of assessment methods should be used to assess practical skills and knowledge. The following examples are appropriate for this unit:

direct questioning combined with review of portfolios of evidence and third party workplace reports of on-the-job performance by the candidate.

Guidance information for assessment

Holistic assessment with other units relevant to the industry sector, workplace and job role is recommended.

Required skills

OHS in relation to operating machinery such as safely switching off machinery before cleaning is started

communication of ideas and information by printing a test file on proofer

collecting, analysing and organising information by determining printing conditions in order to identify colour management requirements

planning and organising activities by clarifying colour requirements before generating a proof

teamwork when maintaining the production process in association with others

mathematical ideas and techniques by using densitometry, spectrophotometry and colour profiles

problem-solving skills by diagnosing and correcting colour problems

use of technology by using software and hardware correctly to ensure consistency of output

Required knowledge

OHS issues need to be considered when managing colour for pre-press

measuring light intensity and colour temperature

standard lighting conditions for matching colour

effects different lighting conditions have on using a monitor, proofing and printing

difference between RGB and CMYK colour

theory behind UCR and the effect it has on an image

theory behind GCR and the effect it has on an image

densitometry and spectrophotometry measure

ICC profiles and why are they used

ICC profiles and how they affect output

factors that influence selection of highlight and shadow aim points

grey balance requirements to be determined prior to applying colour correction

factors that determine the requirements for colour correction

use of different ink densities for different stocks

standard ink densities for different types of job

effects different stocks have on colour reproduction

effects different inks have on colour reproduction for proofing and final production

effects the age and configuration of the press (eg 2-colour vs 4-colour) have on colour reproduction

type of press and what printing process are being used for final output

strengths and limitations with respect to colour reproduction of different printing processes

common problems for colour management and how can they be solved

including an ICC profile in a PDF file

affect using the wrong profile has on output

sources of information about colour management

The range statement relates to the unit of competency as a whole. It allows for different work environments and situations that may affect performance. Bold italicised wording, if used in the performance criteria, is detailed below. Essential operating conditions that may be present with training and assessment (depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts) may also be included.

Test charts may include:

3 and 4-colour neutrals

CMYK colour scales and a range of colour patches.

Spectrophotometers may include:

range of strip reader style devices including

Gretag

Macbeth

Xwrite.

Proofing systems may include:

range of digital proofing systems used in the industry.

Software may include:

range of industry colour applications including colour management software (eg Colorsync), profile creating software, scanner profiling software (eg Colortone Pro, Scan Open), densitometry and spectrophotometry software.

Monitors may include:

range of monitors used in the pre-press sector.

Controlled environment may include:

a controlled environment is one in which temperature and humidity are controlled, the press to be used for the job is known as is, preferably, the printer.

Printing processes may include:

all printing processes.
