Question 1

Which color depth setting produces the smallest file size when scanning black-and-white text documents?

Accepted Answer

1-bit bitonal

Answer

1-bit bitonal scanning stores each pixel as either black or white, producing the smallest possible file size for text documents.

Question 2

What is the primary purpose of an image endorser in a document scanning workflow?

Accepted Answer

To endorse/stamp scanned documents with a batch identifier or sequence number

Answer

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.

Question 3

In digital imaging, what does the term 'interpolated resolution' mean?

Accepted Answer

Resolution artificially increased by software adding pixels between existing ones

Answer

Interpolated resolution uses software algorithms to insert additional pixels between real captured pixels, creating an apparent higher resolution that lacks true detail.

Question 4

Which storage medium is considered MOST appropriate for long-term archival of critical document images under ANSI/AIIM standards?

Accepted Answer

Microfilm or archival-quality optical media (M-DISC)

Answer

ANSI/AIIM standards recognize microfilm and archival-grade optical media as most suitable for long-term preservation due to their proven multi-decade stability.

Question 5

What is 'deskewing' in document image processing?

Accepted Answer

Correcting the angular tilt of a scanned image so text appears straight

Answer

Deskewing detects and corrects the rotational misalignment that occurs when documents are fed at a slight angle into a scanner.
