Updated on

In this Article, you will learn

  • which requirements must be met for this Fixup and
  • how to apply this Fixup.

1. Introduction

The Workflow provides the Fixup Derive Page Geometry Boxes from Crop Marks. The purpose of this Fixup is to set the TrimBox and the BleedBox based on the crop marks.

2. General

The Fixup Derive Page Geometry Box from Crop Marks can be used to derive TrimBox from the existing Crop Marks, and to derive the BleedBox from the crop marks.

Find the Fixup in the Data Preparation tab of an Article, Order or Production Job by:

  • entering the name of the Fixup in the Filter area,
  • activating the option PageBox in the Category area,
  • activating the option Change in the Action area,
  • activating the option Bleed, TrimBox, BleedBox or CropMarks in the Search area.

3. Description

This Fixup allows you to derive the TrimBox from the crop marks and place it correctly. In addition, the Bleed is set to the selected values. Use the dialog to select the Color Spaces from which the TrimBox should be derived.

Outer crop marks are used!

Please note that the TrimBox is derived from the outermost crop marks in the file. If the file uses both crop marks and bleed marks, the TrimBox is derived from the bleed marks.

3.1. Requirements and Functionality

For the Fixup to do what it promises, the following requirements must be met:

  • There are Crop Marks in the file.

Figure 1: The dialog of the Fixup Derive Page Geometry Boxes from Crop Marks.

The following options can be selected to derive the Page Boxes from the Crop Marks:

  • All Color Spaces [1] – enable this option to derive the TrimBox from Crop Marks, regardless of the color space in which they are present.
  • Registration Color (Separation "All") [2] – enable this option to derive the TrimBox from the Crop Marks that are colored with Registration Color (All Separation).
  • Spot Color Black (100% Separation Black) [3] – enable this option to derive the TrimBox from Crop Marks colored with Spot Color Black (100% Separation Black).
  • Grayscale (100% DeviceGray) [4] – enable this option to derive the TrimBox from Crop Marks colored with grayscale colors.
  • CMYK (100% Black) [5] – check this option to derive the TrimBox from Crop Marks colored in CMYK (100% Black) only.
  • CMYK (400%) [6] – check this option to derive the TrimBox from the Crop Marks colored in CMYK (all four channels at 100%).
  • RGB (0/0/0) [7] – enable this option if the TrimBox is to be derived from Crop Marks colored in RGB (0/0/0).
  • If no Crop Marks (Vectors) are found on page [8] – activate this option if the Crop Marks have not been created as vectors but as images. This allows you to activate the options Extract crop marks from rendered pages (any Color Space) [9] and/or the option Raster pages into single image pages [10].
  • Extract Crop Marks on rendered pages (any color space) [9] – activate this option to extract Crop Marks on rendered pages. The color space doesn't influence this option.
  • Raster pages into single image pages [10] – by activating this option, the PDF is temporarily rendered into an image and analyzed with regard to Crop Marks in the raster image. However, the Print Items remain unaffected by this process; only the Page Boxes may be adjusted.
  • Bleed [11] –  enter the desired Bleed for top, bottom, left and right. If the Bleed should differ for the input field, unlock the lock symbol first. For the Variable Content [12], select the desired placeholder  database field or custom field  from which the value for the Bleed of the respective page should be retrieved.

3.2. Before/After

Refer to the example file "Sample_Derive PageBoxes from CropMarks.pdf" to experiment with this function. The file contains Crop Marks but no TrimBox or BleedBox. The TrimBox should be derived from the Crop Marks and the BleedBox should be set at the defined distance from the TrimBox.

After applying the Fixup, the resulting file is "Sample_Derive PageBoxes frim CropMarks_End.pdf". Here, the TrimBox and the BleedBox were placed in the desired position. The values from Figure 1 were used for this.
