In this article, you will learn
- which prerequisites are required for this Fixup, and
- how to apply this Fixup.
1. Introduction
The Fixup Remove BX and EX Entries is available in the Workflow. The purpose of this Fixup is to remove these entries. Page operators that are bracketed by BX and EX can be ignored by a PDF display program if it is not supported.
2. General
The Fixup Remove BX and EX Entries can be used to remove just such entries. If programs want to embed operators in a PostScript code that are not part of the current specification, this can be done using the BX and EX operator. The incompatible operators must be located within the BX and EX operator. Everything within BX and EX will be read and executed by the interpreter, but recognizing an unknown operator will not lead to a PostScript error.
You can find this Fixup on the tab Data Preparation of an Article, Order or Production Job by:
- entering the name of the Fixup in the area Filter,
- activating the option Page Content in the area Category,
- activating the option Delete in the area Action.
3. Description
This Fixup can be used to remove BX and EX entries in the page description. It only removes entries in the PDF that are suppressed during rendering. In some PDF files, this may also eliminate non-existent Spot Color entries. Therefore, this Fixup can be used without restrictions, as moving these entries does not delete any content required for printing.
3.1. Prerequisites and Functionality
For the Fixup to perform as intended, the following requirement must be met:
- BX and EX entries must be included in the PDF.
