In this article, you will learn,
- which prerequisites are required for this Fixup, and
- how to apply this Fixup.
1. Introduction
2. General
This Fixup Resize TrimBox and set Bleed is useful when, after checking in the print data, the TrimBox is not set to the desired size. In addition, the BleedBox can be adjusted to match the TrimBox. The Bleed values must be specified in the Article or Print Item.
You can find this Fixup in the footer of the sections Document Information and User-defined Fields in the tab Print Data of Articles, Production Jobs or Orders or under the tab Data Preparation.
3. Description
This Fixup can be used to adjust the size of the TrimBox by modifying its position on the specified page. In addition, the BleedBox can be set at the defined distance to the TrimBox. You can move the selected side of the box – enlarging it with "+" and reducing it with "-". Note that entering an absolute size for the TrimBox is not possible. All other existing PageBoxes are adjusted automatically to align with the BleedBox.
3.1. Prerequisites and Functionality
For the Fixup to perform as intended, the following requirements must be met:
- The Print Item must have a defined TrimBox.
- The Print Item should already include the appropriate Bleed, as the Fixup does not create additional Bleed automatically.
Figure 1: The dialog of the Fixup Resize TrimBox and set Bleed
Choose from the following options to change the size of the TrimBox:
- Templates [1] – settings selected in the dialog can be saved as a template and applied to other Articles/Print Items, as well as used within Fixup Chains and in the Operations Apply Fixups and Check Print Item and Apply Fixups.
TrimBox [2]
- Top – moves the top edge of the TrimBox ("+" moves up or "-" moves down)
- Bottom – moves the bottom edge of the TrimBox ("+" moves up or "-" moves down)
- Left – moves the left edge of the TrimBox ("+" moves up or "-" moves down)
- Right – moves the right edge of the TrimBox ("+" moves up or "-" moves down)
- Variable Content [4] – for Variable Content [4], select the desired placeholder – Database Field or User-defined Field – from which the values for Top, Bottom, Left and Right should be retrieved.
BleedBox [3]
- Top – creates the BleedBox using the defined distance from the TrimBox on the top edge.
- Bottom – creates the BleedBox using the defined distance from the TrimBox on the bottom edge.
- Left – creates the BleedBox using the defined distance from the TrimBox on the left edge.
- Right – creates the BleedBox using the defined distance from the TrimBox on the right edge.
- Variable Content [5] – for Variable Content [5], select the desired placeholder - database field or user-defined field - from which the values for top, bottom, left and right should be retrieved.
Create the TrimBox
The TrimBox can be easily created using one of the following Fixups: Set TrimBox to the Dieline, Derive PageBoxes from CropMarks, Derive a PageBox from Colored Objects or Set PageBoxes.
3.2. Before/After
To experiment with this function, refer to the sample file "Yard_Sign_no_Bleed_Start.pdf". In this source file, the TrimBox is too large, with an effective width of 560 mm and a height of 400 mm. The BleedBox matches the size of the TrimBox, and the existing Bleed in the file is sufficient.
Since the Print Item will be inserted in a 560 x 390 mm stretcher frame, the height of the TrimBox must be reduced slightly, and the BleedBox must be set according to the existing Bleed. By moving the upper and lower edges by -5 mm each, the TrimBox will match the exact height. The BleedBox is offset by 10 mm from the effective TrimBox.
After applying the Fixup, the corrected file "Yard_Sign_no_Bleed_End.pdf" is created. The MediaBox and the BleedBox are automatically adjusted to match the new size of the BleedBox.
