Notice which vertical line color(s) on the print needs to be moved right or
left to line up as closely as possible with the cyan color line.
Measure how much each line needs to move (in millimeters) and
whether it must be moved left or right.
Cyan is the reference color and does not move. Make
Note
the adjustments of M, Y, and K toward Cyan.
