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 |
Elements and Performance Criteria
ELEMENT | PERFORMANCE CRITERIA |
1 Consult with pre-press bureau about formatting requirements. | 1.1 Source a checklist for printing requirements from appropriate person/s and follow throughout preparation process. 1.2 Obtain relevant specifications for software and image file formatting from appropriate person/s. 1.3 Ensure constraints of different printing processes (and other diffusion techniques) are understood. |
2 Prepare files for pre-press processing. | 2.1 Prepare image files using appropriate pre-press processing techniques. 2.2 Choose suitable test charts/targets and print to appropriate specifications for ink density and stock on a linearised proofer. 2.3 Calibrate digital proofing device to examine test charts and use results to generate colour profile. 2.4 Print test file on calibrated digital proofing device and use results to generate output profile for press and stock. 2.5 Proof sample image and confirm with client. 2.6 Optimise images and output image product to profile specifications using industry standards. 2.7 Save image files in appropriate format for pre-press processing and prepare invoice/account for client. 2.8 Pack completed images for electronic/physical dispatch with invoice/account and deliver to agreed location by appropriate method/s within agreed timeframe. 2.9 Conclude and maintain management procedures. |
3 Wrap up and review print preparation. | 3.1 Catalogue and archive images appropriately. 3.2 Review response from client/s against final printed product. 3.3 Maintain contractual and financial records for business and taxation purposes. 3.4 Review personal performance within job context. 3.5 Identify future opportunities, work directions, equipment needs and workflow changes resulting from job. |
Required Skills
Required skills: research techniques sufficient to access information on colour theory and management (as it applies to pre-press processing) communication skills sufficient to: collaborate/negotiate between client/s and printing bureau discuss colour, its theory and management |
literacy skills sufficient to: interpret a broad range of information on colour theory and management (as it applies to pre-press processing) interpret material specifications necessary for pre-press processing numeracy skills sufficient to: calculate layout requirements/material specifications for pre-press processing compare a colour sampler reading (e.g. eye-dropper value against a 'known value' and calculate a response) determine colour cast and neutrality from a colour sampler reading (e.g. eye-dropper value) identify/assign numeric values to colour as required by pre-press processing read and evaluate Out of Gamut colours and Total Ink/Black Ink limits understand numeric values and meaning against colour theory and how RGB, CMYK and LAB colour values are quantified planning and organising skills sufficient to plan integration of colour management into pre-press processing contexts 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 organisational and OHS requirements associated with pre-press processing and computer usage. |
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. |
Range Statement
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. | |
