PRODPP125 – Plan and capture digital images

Overview

This standard is about capturing material in digital form using either a scanner or a digital camera. It includes detailed intervention where automatic settings do not give the required result.

The standard applies if you produce digital artwork for print or work in a pre-press or digital printing environment.

Subject to the demands of any brief, you are responsible for deciding on the approach you want to take, both creative and technical. You need to have enough flexibility to change your approach when you think it is necessary.

Performance criteria

You must be able to:

Decide on approach

  1. assess the likely quality of images that will be captured from material against customer expectations
  2. inform customers of the advantages and disadvantages of capturing material
  3. inform customers when other approaches may be more suitable
  4. assess the operations necessary to produce the required output
  5. make arrangements to sub-contract any work you cannot carry out in the workplace in accordance with organisational procedures
  6. select the most suitable equipment for the material to be captured and the output required

Prepare equipment and material for capture

  1. carry out any low-resolution image capture necessary to establish the required software values
  2. apply the software values which are appropriate for the material to be captured and the output required
  3. check that the equipment to be used, and the material to be captured are clean
  4. handle the material in a safe manner
  5. load the material in line with manufacturer's instructions

Produce images

  1. produce images which comply with specification in terms of physical size, file size, content, orientation, colour, sharpness, brightness (exposure), contrast, colour space - RGB, CMYK and greyscale and output resolution
  2. produce images which are free of unwanted physical defects, fingerprints, dust damage and scratches, newton's rings, moiré patterning from screened originals, pixelisation, colour, posterisation and halo effects
  3. assess images against customer requirements and workplace standards
  4. detect any problems with the images and identify which are due to faulty capture and which are due to other factors
  5. discuss any problems with colleagues and, where necessary, with customers and agree the action to be taken to resolve problems
  6. follow workplace procedures in dealing with potential problems, recognising any potential legal issues
  7. communicate with customers in accordance with organisational requirements
  8. maintain the confidentiality of customer material in line with organisational procedures
  9. save image data files in the correct format in accordance with organisational requirements
  10. produce images to the correct image profiles in accordance with organisational requirements
  11. maintain version control in line with organisational procedures

Knowledge and understanding

You need to know and understand

  1. the law as it affects printing: defamation, copyright and ownership of images, obscenity, incitement, forgery, data protection
  2. ethical issues relevant to printing: confidentiality, the personal issues important to others, including ethnic origin, gender, religion, sexuality
  3. the hazards and risks in your own job, their assessment and the action to take to deal with them
  4. relevant health and safety regulations on the safe handling of equipment and materials, and the safe use of computer equipment
  5. manufacturer's health and safety requirements relevant to your job
  6. the safe handling of customer material
  7. the secure methods for archiving digital and conventional artwork
  8. how to communicate with customers and colleagues
  9. workplace objectives, priorities, standards and procedures
  10. the identification and assessment of printing options
  11. the reasons for selecting one process over another
  12. the choice of processes for any particular product
  13. the role of images in graphic communication
  14. changing image styles, fashions and demands in printed products
  15. the stages in the printing process from pre-press to printed product
  16. the relationship between resource usage and profitability
  17. how to maximise productivity
  18. the set-up of scanning equipment
  19. the operation of scanning equipment
  20. colour theory, including additive and subtractive systems such as RGB and CMYK colour gamuts
  21. the relationship between image size, file size and resolution
  22. the different file formats for digital images and the reasons for using them
  23. the range of methods, equipment, material and software appropriate to the imaging requirements
  24. the methods of controlling contrast, density and colour characteristics during scanning
  25. the relative merits of the methods, equipment, material and software
  26. how to assess material for capture and the potential problems that may be encountered and their solutions
  27. colour management and how to set up, maintain and use image profiles
  28. how to deal with embedded information
  29. file management procedures
  30. the causes and treatment of common faults in scanning
  31. the main features of quality assurance and quality control systems
  32. techniques for controlling quality, including inspection, testing, sampling, use of input and output controls
  33. light standards for viewing and assessing colour print

Scope/range

Materials

The operator can capture the following material:

  • reflective material, e.g. photographic prints and printed material from books, magazines and newspapers.
  • transparencies and photographic negatives.
  • black-and-white and colour material, including line, halftone and continuous tone.
  • material with a wide range of tonal contrast.
  • a key requirement is the ability to handle safely the material, particularly if this is the property of other people.

Equipment

Whichever device is used, it must be capable of allowing the operator to make adjustments covering the range of adjustments to the scanned image set out in this standard. 'All-in-one' devices at the lower end of the market (e.g. fax-copy-scan-print inkjet devices) are unlikely to have sufficient range of operator-selectable settings for this standard.

Operators are able to capture single and multiple originals and handle complex settings for difficult originals, e.g. originals with limited tonal range and with colour faults.

Discussions with customers

Operators will not have to discuss all of image capture with customers, but will be able to do so when the need arises, e.g. when they have questions, when they have to deal with "difficult" material or when there are problems. The operator will tell customers about capacities and limitations and suggest other approaches where necessary.

Assessment of scanned output

Operators are able to make an accurate assessment of the output and detect any defects and the reasons for them.

Legal issues

Legal issues are, by their nature, difficult to predict and are unlikely to occur in most cases. Operators are aware of the legal knowledge specified for this Standard so that they can spot any potential problems and take the action required in your workplace.
