Zone 4: Scan-axis bidirectional alignment check
This area shows scan-axis bidirectional alignment between colors. As in the description of the previous areas,
in case of misalignment the bottom arrows indicate the pattern of the manual alignment that will correct the
misalignment (I, J patterns). Also, the ‘20’ label indicates the direction in which the line will be moved if a ‘20’
value is applied.
This pattern is formed by a series of vertical lines, printed unpaired as follows:
The correct bidirectional alignment has been found when the Fwd and Rev lines are perfectly aligned.
The following example shows a misalignment situation with an existing correction J=13, and how to correct it.
In this case, the diagram shows that we need to change the value corresponding to the J pattern. Also it
indicates that the correction needs to be moved towards lower values, because the ‘20’ value would move it in
the wrong direction.
Color calibration
Color calibration enables your printer to produce consistent colors with a particular substrate type, even if
printheads, ink cartridges, and environmental conditions change.
