Spine Corner Forming Position Adjustment

You can adjust the cover paper of a perfect-bound book so that the spine is flat.

As an example, this section explains how to adjust the spine when it is 2 mm dented on the forward side.

Meaning and Purpose of Spine Corner Forming Position Adjustment

  • When the spine of a perfect-bound book is not even in the scanning direction or is rounded or dented, this function allows you to adjust the spine so that it is flat, by specifying the desired value. Select the forward side of the spine (Up/Down Forward Adj.) or rear side of the spine (Up/Down Rear Adj.) for adjustment.

  • - value: Makes the spine rounder.

  • + value: Makes the spine straighter.

  • An example of adjusting the forward side of the spine (Up/Down Forward Adj.) is covered below.
