Mount negatives and plates in cameras, set exposure controls, and expose plates to light through negatives to transfer images onto plates.

“Mount negatives and plates in cameras, set exposure controls, and expose plates to light through negatives to transfer images onto plates.” is a supplemental task performed by Prepress Technicians and Workers. Among the occupation's 25 rated tasks, workers place it 6th by importance (#20 most important).

This is a single occupation-specific task statement from O*NET. The figures below describe how central the task is to the job and what independent studies measure about AI and this kind of work — not a prediction that the task will be automated.

AI exposure

The OpenAI / Eloundou “GPTs are GPTs” study rates this task E2. Exposure with tools — software built on top of a language model (not the model alone) could cut the time by at least half.

Exposure measures whether a model could meaningfully speed the task up — it is an estimate of overlap with model capabilities, not a measure of whether the work will be done by software. The study's intermediate score (β) for this task is 0.50. Automation potential label: T0.
