CDIA Quality Control 4

Question 1

When scanning double-sided (duplex) documents, which QC check is specifically required that is not needed for single-sided scanning?

Accepted Answer

Verifying that blank reverse sides are handled correctly per project specifications

Answer

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'?

Accepted Answer

Horizontal or vertical streaks across an image caused by scanner hardware issues

Answer

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?

Accepted Answer

ANSI/ASQ Z1.4

Answer

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?

Accepted Answer

To ensure consistent, accurate image capture by correcting for hardware variations

Answer

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?

Accepted Answer

Adjust scanner brightness and contrast settings, then rescan the affected batch

Answer

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.
