CUVPHI515A
Prepare digital images for pre-press printing

This unit describes the performance outcomes, skills and knowledge required to prepare client image files for pre-press processing.This unit is based on CUVCRS16A Prepare text and graphic files for print processing and ICPPP430A Manage colour and has been contextualised for application to the photoimaging industry.No licensing, legislative, regulatory or certification requirements apply to this unit at the time of endorsement.

Application

This unit applies to the digital imaging industry where image files require processing before printing. It requires the self-directed application of skills and knowledge to prepare digital images for pre-press processing.

This work would usually be carried out independently although guidance would be available if required.


Prerequisites

The following units or demonstrated equivalence are required prior to undertaking this unit:

CUFDIG303A Produce and prepare photo images

CUVPHI07A Process photoimages to work print/file stage

CUVPHI514A Employ colour management in a digital imaging workplace

problem solving skills sufficient to identify/resolve common colour management problems in pre-press processing

technology skills sufficient to use/calibrate scanning and digital proofing devices.

Required knowledge:

colour theory/management associated with pre-press processing

copyright, moral rights, intellectual property and legislative issues associated with pre-press processing

different printing/diffusion techniques and their constraints with respect to design

environmental issues associated with pre-press processing

equipment, tools and materials associated with pre-press processing

Evidence Required

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.

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

Evidence of the following is essential:

production of CMYK, CMYK with spot colour channel and Duo/Tri/Quad tone image files which cause no pre-press processing problems

production of clipping paths (deep etched) to suit the needs of the image and client/job requirements

management of colour in pre-press processing to ensure test prints and final products match.

Context of and specific resources for assessment

Assessment must ensure:

access to an environment where digital image files can be prepared for pre-press processing

access to appropriate sources of information to research colour theory/management

access to appropriate learning and assessment support when required

the use of culturally appropriate processes, and techniques appropriate to the oracy, language and literacy capacity of the assessee and the work being performed.

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 candidate

case studies to assess candidate's ability to manage colour in pre-press processing

direct observation of candidate preparing digital image files for print processing

problem solving activities to assess candidate's critical thinking skills.

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

CUVPHI506A Produce commercial photoimages

CUVPHI508A Produce media photoimages

CUVPHI510A Plan, capture and exploit art photoimages

CUVPHI511A Produce technical photoimages

CUVPHI512A Make illustrative images for publication and display

CUVPHI513A Plan, capture and exploit stock photoimages.
