Question

In measuring ink trapping values of overprint patches and solid color patches, all ink densities must be measured using the

• A. Filter for the first color
• B. Filter for the second color
• C. Filter for the overprint color
• D. Any filter is suitable

Hint:

Proper filtering ensures precise measurement of ink trapping in color overprints.

Answer 1

The Correct Option is C

To accurately measure ink trapping in overprints, the density must be checked using the filter for the overprint color. This ensures proper assessment of how well the second ink layer adheres to the first, providing an accurate reading of trapping efficiency and helping avoid color inconsistencies.
