CDIA Quality Control 4 — Questions and Answers
Question 1: When scanning double-sided (duplex) documents, which QC check is specifically required that is not needed for single-sided scanning?
- Verifying that blank reverse sides are handled correctly per project specifications (Correct answer)
- Checking that the scanner resolution exceeds 300 DPI
- Confirming that TIFF format is used for all output
- Ensuring that color images are converted to grayscale
Correct answer: Verifying that blank reverse sides are handled correctly per project specifications
Duplex scanning requires a policy for blank reverse pages—whether to include or discard them—and QC must verify this rule is applied consistently.
Question 2: In quality control for document imaging, what is 'banding'?
- Horizontal or vertical streaks across an image caused by scanner hardware issues (Correct answer)
- The grouping of documents into processing batches
- A compression artifact in JPEG images
- The method of organizing files into folders
Correct answer: Horizontal or vertical streaks across an image caused by scanner hardware issues
Banding appears as repeating horizontal or vertical lines in scanned images, typically caused by a dirty or damaged scanner glass or lamp issues.
Question 3: Which acceptance sampling standard is commonly referenced in document imaging QC programs to determine sample sizes and acceptable quality levels?
- ANSI/ASQ Z1.4 (Correct answer)
- ISO 27001
- MIL-STD-810
- NFPA 72
Correct answer: ANSI/ASQ Z1.4
ANSI/ASQ Z1.4 provides attribute sampling plans widely adopted in document imaging QC to determine statistically valid sample sizes and AQL thresholds.
Question 4: What is the purpose of scanner calibration in a document imaging quality program?
- To ensure consistent, accurate image capture by correcting for hardware variations (Correct answer)
- To set the network speed for image transfer
- To configure the document management software interface
- To establish user access permissions for the imaging system
Correct answer: To ensure consistent, accurate image capture by correcting for hardware variations
Scanner calibration uses reference targets to correct for lamp aging, sensor drift, and other hardware variations that degrade image quality over time.
Question 5: A document imaging project discovers that 8% of scanned images have illegible text due to low contrast. What is the most appropriate corrective action?
- Adjust scanner brightness and contrast settings, then rescan the affected batch (Correct answer)
- Apply OCR post-processing to reconstruct the text
- Increase the file compression ratio to enhance sharpness
- Change the output file format from TIFF to PDF
Correct answer: Adjust scanner brightness and contrast settings, then rescan the affected batch
Low contrast issues are a scanning parameter problem that must be corrected at the source by adjusting scanner settings and rescanning—not through post-processing.
Question 6: Which element of a quality control checklist specifically addresses whether all pages of a multi-page document are present and in correct order?
- Completeness and sequence verification (Correct answer)
- Resolution conformance check
- Compression ratio audit
- File naming convention review
Correct answer: Completeness and sequence verification
Completeness and sequence verification ensures that no pages are missing, duplicated, or out of order within a scanned multi-page document.
Question 7: In a large-scale document imaging QC program, what is the primary advantage of implementing a 'tiered' quality review process?
- It allocates intensive inspection resources to higher-risk document types while applying lighter review to lower-risk documents (Correct answer)
- It allows QC to be skipped for documents scanned by experienced operators
- It reduces the total number of documents that must be scanned
- It eliminates the need for automated QC software
Correct answer: It allocates intensive inspection resources to higher-risk document types while applying lighter review to lower-risk documents
A tiered QC approach applies risk-based resource allocation, concentrating thorough inspection where errors would have the greatest impact.
