Acobat 8.3 creates bounding box around hyperlink in InDesign CS2 file. Here is our work flow and problem:
1. Original article is submitted in MS Word, in which the author has embedded hyperlinks that appear appropriately in blue, underscored text. It is edited and proofread in Word. Once done, text and paragraph formatting is applied while still in Word (much faster here than in InDesign).
2. Word file is placed in InDesign CS2. Hyperlinks appear correctly.
3. Using the InDesign export function (not "print to" PDF) file is exported to Acrobat 8.3, "include hyperlinks" box is selected.
4. Acrobat 8 creates PDF, however it creates a hairline bounding box around all hyperlink text!
In PDF a "link" is provided by the Link annotation. It is not a part of the PDF page content.
An annotations "box" defines the annotations location on the specific PDF page.
For a Link it is the means of associating the action performed by the annotation and the character string in the PDF page content.
In short, the "box" is supposed to be present.
For reference, see Section 12.5.6 of ISO 32000-1 (ISO Standard for what PDF 'is').
