☛ Transfer images from master plates to unexposed plates, and immerse plates in developing solutions to develop images.

☛ Examine unexposed photographic plates to detect flaws or foreign particles prior to printing.

☛ 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.

☛ Examine finished plates to detect flaws, verify conformity with master plates, and measure dot sizes and centers, using light-boxes and microscopes.

☛ Perform close alignment or registration of double and single flats to sensitized plates prior to exposure, in order to produce composite images.

☛ Remove plate-film assemblies from vacuum frames, and place exposed plates in automatic processors to develop images and dry plates
