Engineering:Drop-out ink
From HandWiki
Short description: Type of ink ignored by OCR scanners
 | This article relies largely or entirely on a single source. (June 2024) |
Drop-out ink is ink specifically colored to avoid reading in high-speed OCR scanners. It is often a pastel yellow, red or orange.
The purpose for dropping out specific colors is to allow the OCR scanner to ignore those colors and operate only on the foreground information.[1]
Drop-out ink is often used in the finance industry for automated paper invoice processing.
Drop-out ink is not the same as inks that have been screened down.
