Tasks

  • Activate scanners to produce positive or negative films for the black-and-white, cyan, yellow, and magenta separations from each original copy.
  • Analyze originals to evaluate color density, gradation highlights, middle tones, and shadows, using densitometers and knowledge of light and color.
  • Arrange and mount typeset material and illustrations into paste-ups for printing reproduction, based on artists' or editors' layouts.
  • Correct minor film mask defects with litho tape or opaquing fluid.
  • Enter, position, and alter text size, using computers, to make up and arrange pages so that printed materials can be produced.
  • Enter, store, and retrieve information on computer-aided equipment.
  • Examine finished plates to detect flaws, verify conformity with master plates, and measure dot sizes and centers, using light-boxes and microscopes.
  • Examine photographic images for obvious imperfections prior to plate making.
  • Examine unexposed photographic plates to detect flaws or foreign particles prior to printing.
  • Inspect developed film for specified results and quality, using magnifying glasses and scopes; forward acceptable negatives or positives to other workers or to customers.
  • Lower vacuum frames onto plate-film assemblies, activate vacuums to establish contact between film and plates, and set timers to activate ultraviolet lights that expose plates.
  • Maintain, adjust, and clean equipment, and perform minor repairs.
  • Mix solutions such as developing solutions and colored coating solutions.
  • Monitor contact between cover glass and masks inside vacuum frames, in order to prevent flaws resulting from overexposure or light reflection.
  • Mount negatives and plates in cameras, set exposure controls, and expose plates to light through negatives in order to transfer images onto plates.
  • Operate and maintain a variety of cameras and equipment, such as process, line, halftone, and color separation cameras, enlargers, electronic scanners, and contact equipment.
  • Operate and maintain laser plate-making equipment that converts electronic data to plates without the use of film.
  • Operate presses to print proofs of plates, monitoring printing quality to ensure that it is adequate.
  • Perform close alignment or registration of double and single flats to sensitized plates prior to exposure, in order to produce composite images.
  • Perform minor deletions, additions, or corrections to completed plates, on or off printing presses, using tusche, printing ink, erasers, and needles.
  • Perform tests to determine lengths of exposures, by exposing plates, scanning line copy, and comparing exposures to tone range scales.
  • Place masking paper on areas of plates not covered by positives or negatives, in order to prevent exposure.
  • Position and angle screens for proper exposure.
  • Position color transparencies, negatives, or reflection copies on scanning drums, and mount drums and heads on scanners.
  • Punch holes in light-sensitive plates and insert pins in holes to prepare plates for contact with positive or negative film.
  • Remove plate-film assemblies from vacuum frames, and place exposed plates in automatic processors to develop images and dry plates.
  • Reposition lamps and adjust aperture controls in order to provide high quality images.
  • Scale copy for reductions and enlargements, using proportion wheels.
  • Select proper types of plates according to press run lengths.
  • Set scanners to specific color densities, sizes, screen rulings, and exposure adjustments, using scanner keyboards or computers.
  • Transfer images from master plates to unexposed plates, and immerse plates in developing solutions to develop images.
  • Unload exposed film from scanners, and place film in automatic processors to develop images.
