Welcome to the National Council National Council Flexographic Practice Test

Below is a practice test to gauge your knowledge and expertise on the flexographic printing process. This is not a pass/fail test, rather helps you determine how prepared you are to take other tests offered by the National Council. All questions and answers are copyrighted material and are the sole property of the National Council for Print Industry Certifications.

1. A test of ink adhesion to film substrates is a:

2. The UPC printed on a flexo press will not scan. A verifier indicates a bar growth problem. What should the press operator do first:

3. A four-color process print appears to have a magenta cast. The anilox and plate pressures are set accurately. Density readings started at: Y=1.00; M=1.34; C=1.35; K=1.51. Now Magenta has increased to 1.54. To correct the problem you should first:

4. Slipping of successive winds of a material roll so that the edge is conical rather than flat is called:

5. The appearance of a halo around all printed areas could be caused by:

6. A scored anilox roll could cause which of the following print defects:

7. Mottling can be caused by which of the following?

8. When running a four color press job and a void of all four colors is detected in an area where they all overprint, the problem could be:

9. The industry standard light source for viewing color is:
