Elements and Performance Criteria

1. Calibrate proofing device
   • Machine calibration is checked for conformance to job specifications
   • Appropriate International Colour Consortium (ICC) profiles are applied to meet colour requirements
   • Paper for outputis matched to profile
2. Produce proofs from digital data
   • Image is retrieved from the database using industry software
   • Data file is checked for structural compatibility with capability of the Raster Image Processor (RIP)
   • Special colours are sent to the RIP where appropriate
   • Proof is produced according to job specifications and workflow procedures
   • Proof is evaluated against job specifications using a densitometer, and checked against changes and original working data
   • Proof is prepared for client submission
   • Proof is used as a contract proof only if RIP is the same for both proof and film, and if client accepts it as such

Performance Evidence

Evidence of the ability to:

transfer underlying skills of proofing across the design and pre-press sectors

identify the substrate for reproduction and ensure quality of image is suitable for the printing process

produce image file(s) compatible with a Raster Image Processor (RIP) including an example with special colours

produce proofs to job specifications and client submission using quality control devices and colour evaluation charts.

Note: If a specific volume or frequency is not stated, then evidence must be provided at least once.

list constraints on file structure imposed by RIP

describe the function of an International Colour Consortium (ICC) profile

list differences that various RIPs can have on output

Use of quality control devices for colour appraisal

describe how a densitometer is used for proof evaluation

explain the function of calibration software for the output device

explain the purpose of colour evaluation charts and how they are used

Evaluation of the proof

list criteria for evaluating a colour proof

explain differences that can occur between preliminary proofs and a contract proof
