# How can a printer or bindery use computer vision to inspect books, catalogs and booklets?
Cameras on the binding line check each book, catalog or booklet as it moves through gathering, binding and trimming, and flag missing, doubled or out-of-order sections, crooked covers, glue spills, torn or wrinkled spines and rough or uneven trims for a person to check. Each flag is saved with a photo and the job and time, so a drift in the gatherer, binder or trimmer shows up sooner. A line lead decides what is pulled, and the usual page count, pull and customer proof checks stay in place.
## What this means in practice
- Cameras read the small marks or codes printed on each section as it is gathered, and take pictures of each book or booklet after binding, covering and trimming.
- The model is trained on the clients own jobs and layouts. It flags missing, doubled or out-of-order sections, covers that are crooked or upside down, glue spills, torn or wrinkled spines, loose staples, and trims that are rough, uneven or too close to the print.
- Each flag is saved with a photo, the job, the machine and the time, so the team can see when the gatherer, binder, stitcher or trimmer starts to drift.
- A line lead checks the flags and decides what is pulled or reworked. The cameras point at the product, not at workers, and any people caught in view are blurred.
- Start with one line and one job type, compare the camera flags with what the crew finds for a few weeks, and keep the existing page count, pull, proof and customer checks in place.
