For the Fixup to perform as intended, the following requirements must be met:

• A TrimBox must exist in the Print Item. The MediaBox is present in every PDF file by default.
• The BleedBox may be present.
• The Bleed for the Print Item must already be defined.

Figure 1: The dialog Set PageBoxes  

You can choose from the following options:

• Starting point [1] – determines the reference from which the PageBoxes will be adjusted. There are nine options to choose from:
  • Center – sets the width and height of the MediaBox or TrimBox relative to the horizontal and vertical center of the Print Item.
  • Upper Left Corner – sets the width and height of the MediaBox or TrimBox relative to the upper-left corner of the Print Item.
  • Upper Right Corner – sets the width and height of the MediaBox or TrimBox relative to the upper-right corner of the Print Item.
  • Lower Left Corner – sets the width and height of the MediaBox or TrimBox relative to the lower-left corner of the Print Item.
  • Bottom Right Corner – sets the width and height of the MediaBox or TrimBox starting from the horizontal and vertical bottom right corner of the Print Item.
  • Top Center – sets the width and height of the MediaBox or TrimBox relative to the top center of the Print Item.
  • Bottom Center – sets the width and height of the MediaBox or TrimBox relative to the bottom center of the Print Item
  • Center Left – sets the width and height of the MediaBox or TrimBox relative to the center-left of the Print Item.
  • Center Right – sets the width and height of the MediaBox or TrimBox relative to the center-right of the Print Item.
  • Variable Content [5] – for Variable Content [5], select the desired placeholder – Database Field or User-defined Field – from which the value for the starting point is retrieved. The following value has to present in the selected field so that the starting point is carried out:
    • Center
    • UpperLeft
    • UpperRight
    • LowerLeft
    • LowerRight
    • Top
    • Bottom
    • Left
    • Right

Figure 2: Values in the selected field for the option Starting point

MediaBox [2] – by entering the values determine how the MediaBox should change.

• Width – displays the current width of the MediaBox. Entering a different value will recreate the width of the MediaBox, starting from the selected starting point.
• Height – displays the current height of the MediaBox. Entering a different value will recreate the width of the MediaBox, starting from the selected starting point.
• Variable Content [6] – select the desired placeholder – Database or User-defined Field – from which the value for the height or width or the x- and y offset should be retrieved.

TrimBox [3] – by entering values determine how the TrimBox should change.

• X-Offset – specifies the offset by which the width of the TrimBox is to be shifted, starting from the selected starting point.
• Y–Offset – specifies the offset by which the height of the TrimBox should be shifted starting from the selected starting point.
• Width – displays the current width of the TrimBox. By entering another value, the width of the TrimBox, starting from the selected starting point plus X–offset, will be newly created.
• Height – displays the current height of the TrimBox. Entering a different value will recreate the height of the TrimBox, starting from the selected starting point plus Y offset.
• Variable Content [7] – select the desired placeholder – Database or User-defined field – from which the value for the height or width should be retrieved.

BleedBox [4] – by entering values determine at which distance the BleedBox should be set to the TrimBox

• Top – creates the BleedBox at the defined distance from the TrimBox on the top.
• Bottom – creates the BleedBox at the defined distance from the TrimBox on the bottom.
• Left – creates the BleedBox at the defined distance from the TrimBox on the left.
• Right – creates the BleedBox at the defined distance to the TrimBox on the right.
• Variable Content [8] – select the desired placeholder – Database or User-defined Field – from which the value for the height or width should be retrieved.

To experiment with this function, refer to the sample file "Set PageBox Start". In this source file, the MediaBox has a size of 600 x 400 mm, and the TrimBox has a size of 430 x 280 mm. The BleedBox is positioned exactly over the TrimBox.

Task: The Print Item should be produced with a visible format of 420 x 280 mm and a Bleed of 10 mm, resulting in a production format of 440 x 300 mm. In addition, the crop for the visible format should be shifted 10 mm to the right to highlight a more interesting image detail.

After applying the Fixup, the final version "Set PageBox End" is created. Note that by offsetting the TrimBox by 10 mm and adding a 10 mm Bleed on the right side, the Print Item may not have sufficient Bleed. To synchronize the MediaBox and CropBox with the BleedBox, we recommend using the Fixup Synchronize Selected Page Geometry. This is necessary because, when the TrimBox is offset, the MediaBox can be resized but cannot be offset.
