Test Pattern 4: Color Alignment Quality Test
This test pattern is to check the color alignment, and produces six patterns each with
two different primary colors. In each pattern you will see primary color circles. If
there is misalignment between the primary colors the composite color will be
present in one part of the circle and white will be visible at the opposite side of the
circle.
There are two types of misalignment (See Example F ):
n Horizontal - when the misalignment is in the horizontal axis
n Vertical - when the misalignment is in the vertical axis
