CDT Document Imaging & Digital Storage 3 — Questions and Answers
Question 1: What is the recommended scanning resolution for capturing fine-detail engineering drawings for archival purposes according to AIIM guidelines?
- 400 DPI or higher (Correct answer)
- 72 DPI
- 150 DPI
- 200 DPI
Correct answer: 400 DPI or higher
Engineering drawings with fine lines and detailed annotations typically require 400 DPI or higher to ensure all detail is captured accurately for archival use.
Question 2: In a document imaging system, what is a 'batch header sheet'?
- A separator page scanned at the start of a batch that carries index data or batch identifiers (Correct answer)
- A printout summarizing the scan job statistics
- A quality control checklist for operators
- The first page of every document in a batch
Correct answer: A separator page scanned at the start of a batch that carries index data or batch identifiers
A batch header sheet is a physical separator page placed before a set of documents that contains indexing information readable by the capture software.
Question 3: Which image file format natively supports multiple pages within a single file, making it well-suited for multi-page document storage?
- Multi-page TIFF (Correct answer)
- BMP
- PNG
- JPEG
Correct answer: Multi-page TIFF
TIFF supports multi-page (multi-image) storage within one file, a feature not natively available in JPEG, PNG, or BMP formats.
Question 4: What is 'index verification' in the context of document capture?
- A quality check confirming that metadata index values accurately correspond to the correct document images (Correct answer)
- Verifying the file index table on a storage device
- Checking that index terms appear in the document text
- Confirming an index file was saved to the correct directory
Correct answer: A quality check confirming that metadata index values accurately correspond to the correct document images
Index verification ensures that the metadata (document number, date, author, etc.) captured or keyed during scanning correctly matches the content of the associated image file.
Question 5: What does 'throughput' measure in scanner performance specifications?
- The number of pages or images a scanner can capture per minute (Correct answer)
- The file size output of a scanned image
- The maximum document length the scanner can handle
- The speed at which images are transferred from scanner to workstation
Correct answer: The number of pages or images a scanner can capture per minute
Throughput, expressed in pages per minute (PPM) or images per minute (IPM), measures the scanning speed under specified conditions.
Question 6: Which process automatically detects and removes entirely blank pages from a scanned document set?
- Blank page deletion (Correct answer)
- Deskewing
- Binarization
- Despeckling
Correct answer: Blank page deletion
Blank page deletion software analyzes each scanned image and discards pages that contain no meaningful content, reducing storage requirements.
Question 7: In document imaging, what is the function of an 'optical character recognition confidence score'?
- A numeric indicator of how accurately the OCR engine believes it recognized a particular character or word (Correct answer)
- A rating of scanner optical quality
- A measure of document image contrast
- An assessment of compression ratio effectiveness
Correct answer: A numeric indicator of how accurately the OCR engine believes it recognized a particular character or word
OCR confidence scores help identify characters or zones where recognition is uncertain, flagging them for human review to improve data extraction accuracy.
