Refer to Figure 7.5.3.5. Observe the three image areas on several System Controller Test
Patterns. Check the resolution of the images in each of the areas:
Area 1:
When set at 600 DPI, the two pixel vertical, horizontal and diagonal lines should be clear and
continuous. The diagonal lines might appear to be narrower than the others.
Area 2:
The text paragraphs should be roughly equal in density.
Area 3:
The half-tone patches adjacent to the solid blocks in the corners should be uniform in
appearance.
