Center Along Height
Centers the imposition plan along the vertical axis of the media.
Shift Along Width
(See

)
Available if the
Center Along Width
check box is cleared.
Shifts the imposition plan from the left edge of the media along
the horizontal axis.
Shift Along Height
(See

)
Available if the
Center Along Height
check box is cleared.
Shifts the imposition plan from the bottom edge of the media
along the vertical axis.
Flat Rotation
Makes a small angle rotation of the flat or output image. Also
called plate cocking. Derive the
(0.0)
percentage value, or
gradient, in one of two ways:
●
Physically measure the first occurrence of a rotation to find
the gradient that you can then apply for all jobs that use that
rotation
●
Convert a given angle into its gradient
To measure for a gradient:
●
Formula: gradient = rise/run x 100 where:
●
Rise: (y-axis) measure the distance between where the flat's
rotating corner started and where it must be moved as a
straight line that meets the x-axis at a 90° angle. Example: 2
units
●
Run: (x-axis) measure the distance along the x-axis from the
non-rotated corner of the flat to the point where the vertical
line transects the x-axis at a right angle. Example: 90 units
●
Calculation: 2/90 x 100 = 2.2
●
The maximum percentage value is 3.1.
