Transcription

1 Unit Credit Value: 6 Unit Level: Three Unit Guided Learning Hours: 50 Ofqual Unit Reference Number: M/600/9001 Unit Review Date: 31/12/2016 Unit Sector: 9.3 Media and Communication Unit Summary In this unit learners will undertake colour management procedures. This involves calibrating and profiling hardware to maintain colour accuracy from image capture to output and is likely to include using a range of technology and equipment including, digital cameras, scanners, monitors, proofing devices and printers. Unit Information It is expected that before the unit is delivered, the tutor will have read the Qualification Specification to ensure all conditions regarding Rules of Combination, delivery, assessment and internal quality assurance are fulfilled. Additional guidance is available below as Assessment Guidance for Learning Outcomes and Assessment Criteria in bold. This unit has 5 learning outcomes 1. Understand key issues relating to undertaking colour management procedures 1.1. Explain the principles of colour theory, colour mode and colour profiles 1.2. Explain the process of a colour managed workflow from image capture to image output 1 of 5

3 5. Understand health and safety and business requirements relating to undertaking colour management procedures 5.1. Identify relevant aspects of health and safety legislation 5.2. Take appropriate action to minimise potential risks and hazards 5.3. Check that all business procedures are followed Assessment Guidance Learning Outcome Colour theory, colour mode and colour profiles: Additive primary colours for monitors and displays(rgb) Subtractive primary colours for printing (CMYK) Conversion of RGB colour mode to CMYK colour mode Proofing colours for print Use of 8/16 bit colour editing modes where supported by image capture and image editing software Use of embedded colour profiles in photo images and conversion to working colour space in image editing applications 1.2 Colour managed workflow: use of a fully colour managed workflow to ensure accurate colour reproduction in final work; requirements of colour profiles to be used at image capture e.g. either srgb or Adobe RGB colour profile selected in a digital camera; how image colour profiles are stored with image files throughout the process and used alongside colour calibrated hardware e.g. computer monitor and printer. Learning Outcome Hardware devices: to include: Camera Scanner Display monitor Printer 2.2 Equipment used for calibration: to include for example: Colorimeter Spectrophotometer Colour checker chart Grey scale chart Scanner profiler chart 3 of 5

4 Pantone library 2.3 Controlling the environment of the digital workplace: digital workplace environment to include, for example, ambient light e.g. natural or artificial; neutral grey work surfaces and walls. Effect of ambient lighting on calibration and the human eye; effect of coloured work surfaces and walls on how colours are interpreted by the human eye; how these effects can lead to over compensation of colour inaccuracies in image files. 2.4 Reference material and test cards: to include for example: Colour checker chart Grey scale chart Scanner profiler chart Pantone library 2.5 Calibrate: use colour calibration equipment to: Calibrate a display monitor, using appropriate hardware and software Calibrate a scanner, using appropriate hardware and software Calibrate a printer, using appropriate hardware and software 2.6 Create and store: save the new profile(s) created as a result of colour calibration; ICC and ICM profiles. 2.7 Colour calibration profiles: identify where new profiles are stored on the computer system; configure the operating system and image editing software applications to load the new profiles as required. 2.8 Monitor: compare test prints with reference material e.g. colour charts; identify calibration intervals for each piece of hardware; check for drift and ageing of hardware devices in terms of colour reproduction accuracy. Learning Outcome Embedded colour profile: check image file information and properties; identify what colour profile is embedded. 3.2 Assign and/or convert embedded colour profiles to image: identify organisation policies and procedures for working with colour profiles; assign colour profiles to images that do not have embedded colour profile; convert embedded colour profile to required working colour space. 3.3 Appropriate embedded profile: colour profiles supported by different devices e.g. display monitors, printers; assign or convert embedded colour profile to be srgb for screen/web use. 4 of 5

5 3.4 Appropriate printer profile: colour profiles supported by different devices e.g. display monitors, printers; assign or convert embedded colour profile for print use e.g. using Adobe RGB, ProPhoto RGB. Learning Outcome Intended future use of images: consider whether images created for screen/web use will ever be printed; limitations of permanently restricting colour gamut by saving images only with srgb profile. 4.2 Record and store information: maintain accurate records; identify dates of calibration, profile names stored and next calibration date due. 4.3 Master copy of images: store high resolution, high quality images with appropriate embedded profiles; create lower resolution copies with srgb profiles for screen/web use if and when required. Learning Outcome Health and safety legislation: review organisational health and safety policies; solitary working if applicable; use of computer and electrical equipment; review work area in terms of local hazards, risks, fire evacuation routes, first aid facilities. 5.2 Minimise potential risks and hazards: check information provided on a risk assessment regarding action to be taken to minimise risks. To include for example: Ergonomics of computer use Scheduling of regular breaks Periodic portable appliance testing (PAT) of electrical equipment 5.3 Business procedures: identify business/organisation systems and procedures related to technical adjustment of images; comply with procedures relevant to own work. Delivery Requirements Appropriate physical resources will be required in order to deliver and assess this unit. Evidence Requirements Evidence of practical ability must be demonstrated. 5 of 5
