Which document imaging defect is characterized by dark spots or marks appearing on scanned images that were not present on the original document?
Answer: Speckling or noise
Speckling or image noise appears as random dark pixels on the scanned image, typically caused by dust on the scanner glass or sensor imperfections.
What is the recommended approach when a QC inspector finds that an entire day's scanning production fails to meet quality standards?
Answer: Halt production, identify and fix the root cause, then rescan the entire affected batch
When a full day's production fails QC, the root cause must be corrected before rescanning to prevent the same defects from recurring.
In document imaging, what does 'Acceptable Quality Level' (AQL) define?
Answer: The maximum percentage of defective items considered acceptable in a sampled batch
AQL is the worst acceptable average quality level in a sampling plan; batches with defect rates at or below the AQL are accepted, while those above are rejected.
Which post-scan image processing step directly improves OCR accuracy by straightening tilted text lines within an image?
Answer: Deskewing
Deskewing algorithmically rotates a tilted scanned image to align text lines horizontally, which significantly improves OCR recognition accuracy.
A CDIA project manager wants to track QC performance trends over time. Which tool is most useful for visualizing whether the defect rate is remaining stable or drifting?
Answer: Statistical process control (SPC) chart
SPC charts plot defect rates over time and use control limits to distinguish normal variation from statistically significant quality trends or shifts.
What is the significance of maintaining a 'quality control log' throughout a document imaging project?
Answer: It provides an auditable record of defects found, corrective actions taken, and final disposition of batches
A QC log creates an audit trail demonstrating that quality standards were monitored and enforced, which is essential for compliance and process improvement.
During a document imaging QC review, an inspector notices that 5% of images have headers and footers cut off. What scanner setting most likely caused this issue?
Answer: Incorrect page size or crop settings
Incorrect crop or page size settings cause the scanner to capture a smaller area than the actual document, resulting in clipped margins and missing content.
