Me encontré con la siguiente información espero te sirva. Desgraciadamente no encontré nada en español. Pero es posible que basandote por la definición, puedas llegar a una buena traducción.
Bluelines - An image of your artwork made on photosensitive paper by exposing it to a light source through photographic negatives made from the art. The paper reproduces the artwork exactly, usually in blue, and is therefore called a "blueline". The purpose of a blueline is to check the accuracy of the image itself, by comparing them with your camera-ready art. This is not the place to make editorial changes. Changes at this stage are very expensive. http://oc.nci.nih.gov/services/printing_d.html

BLUELINES AND COLOR PROOFS
A blueline is a one-color representation of what your job will look like. This is the final stage at which to make any corrections; however, please remember that any changes at this point will usually require correcting and reoutputting the film and making a revised blueline. These last-minute changes can be costly and could delay delivery dates.
