Even minor changes in InCopy and InDesign affect the layout of the document
While the Table tagging and the TextBlock tagging of the CtrlPrint Frames are pretty stable from one version of the annual report to another, layouts modifications can have an impact on the restoration of the previous tag mapping. Some of the tags can be lost to unresolved mappings or text selections can be altered with different starting or end points.
We have run some tests on the current best configuration for improving the text block tagging restoration. Please be aware that the suggestions on this page can have an affect on the tagging that is currently on the page, but their intention is to potentially prevent as much amending to be required later in the process.
In the ESEF settings of the chapters eligible to ESEF or in the ESEF settings of the whole project, The selection of the Force mode for the option “PDF Unicode CMAPs Handling” was already helping a lot in order to prevent the presence of hidden data in the XHTML documents.
As this option improves the quality of the XHTML version of the annual report, it also improves the consistency of the selected text zones from a version to another if the zone has been manually selected.
Important note: If the tables in InDesign/InCopy are not built using the actual tables functionality but with spaces and tabs, columns will not be correctly aligned. Therefore we strongly recommend using the functions to create a table in InDesign if you intend on changing this setting
Manual text selection
In the tagger, there are two ways to select a text zone where to apply a TextBlock tag:
- To manually select a text by moving the selection blue dots to the beginning and the end of the text (Manual text selection).
- To select a geometric text area by holding the shift touch key (Area selection).
The manual text selection (used with the CMAP force mode) is less sensitive to layouts modifications. The layout modification described previously wouldn’t impact the tagged text zones.
The area selection, as it uses mainly the geometric positions of the elements in a page, is very sensitive to changes in the document layout. For example, moving text down a few rows could modify the starting and end points of each granular tag.
We recommend that you use the manual text selection as much as possible with the Force setting above applied.
- Regardless of the settings or selection mode, if a tag starts on a page and continues on the following page, modifications that will move the page break might result in a hole in the tagged text block where the former page break was.
- If the master tag “Disclosure of notes and other explanatory information” has been applied with the “Tagging text block from page to page” feature then it uses the functionality of the geometric text area selection by holding the shift touch key. This implies that any layout modifications will probably have an impact on the restoration of this tag. We recommend applying this tag as a final step of the report creation.
