Elements and Performance Criteria

1. Evaluate copy
   • Copy is scaled and gradation aim points selected to produce required output
   • Screen rulings, angles, tone gradation, dot percentages, and dot shapes are selected according to job specifications
   • Rescreens and mono conversions from colour originals are evaluated for reproduction requirements
2. Prepare for exposure
   • Camera is cleaned and prepared and lights are set to deliver an even distribution of light
   • Exposure program is set according to stock and print conditions
   • Densities are measured on copy according to evaluation
   • Exposure programs for special effects and duotones are calculated to deliver job requirements
3. Process and evaluate image
   • Processor is checked and maintained within tolerances
   • Film is processed according to job specifications
   • Image is checked for size, gradation, cleanliness and dot percentages according to job specifications
4. Solve technical photographic problems
   • Technical problems relevant to tone and reproduction of photographic images are resolved by reassessing elements for photography, camera operations or brief amendment in consultation with client
   • Images are photographed with potential to be reproduced according to the brief

Performance Evidence

Evidence of the ability to:

correctly use a graphic arts camera to photograph and process at least THREE continuous tone originals with different contrast characteristics according to the specific job requirements.

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

Knowledge Evidence

To complete the unit requirements safely and effectively, the individual must:

describe how halftone images are varied to suit different printing processes

describe main characteristics of a halftone image and factors that influence selection of highlight and shadow points (first and last printing tones)

outline process of overcoming problems associated with reproduction of screened copy

describe method of calibrating densitometer and copy measurement

outline preparation of a basic exposure program and factors that influence basic exposure data

describe process for applying exposure data to selected copy and factors that could cause a change of exposure, including use of a grey scale to assist in exposure control

outline criteria for evaluation of a halftone image and affect a change to processing conditions may have on the final result

describe image requirements for various printing processes

outline evaluation criteria for a duotone

identify manuals, safety and other documentation relevant to this task, where are they kept and information included in these documents.
