Which color depth setting produces the smallest file size when scanning black-and-white text documents?
Answer: 1-bit bitonal
1-bit bitonal scanning stores each pixel as either black or white, producing the smallest possible file size for text documents.
What is the primary purpose of an image endorser in a document scanning workflow?
Answer: To endorse/stamp scanned documents with a batch identifier or sequence number
An image endorser physically stamps or imprints documents as they pass through the scanner to indicate they have been captured and to apply tracking identifiers.
In digital imaging, what does the term 'interpolated resolution' mean?
Answer: Resolution artificially increased by software adding pixels between existing ones
Interpolated resolution uses software algorithms to insert additional pixels between real captured pixels, creating an apparent higher resolution that lacks true detail.
Which storage medium is considered MOST appropriate for long-term archival of critical document images under ANSI/AIIM standards?
Answer: Microfilm or archival-quality optical media (M-DISC)
ANSI/AIIM standards recognize microfilm and archival-grade optical media as most suitable for long-term preservation due to their proven multi-decade stability.
What is 'deskewing' in document image processing?
Answer: Correcting the angular tilt of a scanned image so text appears straight
Deskewing detects and corrects the rotational misalignment that occurs when documents are fed at a slight angle into a scanner.
Which TIFF compression option is lossless and specifically designed for bitonal (black-and-white) document images?
Answer: CCITT Group 4
CCITT Group 4 (also called G4) is a lossless fax-based compression standard optimized for bitonal document images and widely used in document management.
What does 'document destruction certification' refer to in a records management context?
Answer: A formal document attesting that physical records were destroyed after imaging verification
Destruction certification is a legally significant record confirming that physical originals were properly disposed of after digitization and quality verification.
