Perform tests to determine lengths of exposures, by exposing plates, scanning line copy, and comparing exposures to tone range scales.

“Perform tests to determine lengths of exposures, by exposing plates, scanning line copy, and comparing exposures to tone range scales.” is a supplemental task performed by Prepress Technicians and Workers. Among the occupation's 25 rated tasks, workers place it 2nd by importance (#24 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: T1.
