See the image below, I'm having trouble with InDesign it just keeps creating a grey border on the edge of any document but only on the left side? There are no bleed settings and the line isn't physically there. But easily identifiable when opened in Acrobat.
The grey on each side of the document is the default acrobat background panel, you can see the right side of the document is seamless with the back panel, the left though shows this mystery line. Is this perhaps something to do with overprint/pixel-perfection? Thanks in advance community.
Machine: Win8.1 InDesign/Acrobat PRO DC CC 2015.
Your screenshot is too small.
Why are you not using a bleed, if it is print?
Sorry they are terrible,
Herewith 2 screenshots of files that were exported with the exact same settings but one with Acrobat PRO DC running in the background and one without. It seemed that running Acrobat PRO DC in the background whilst exporting from InDesign caused the top/left grey border. Perhaps the issues is within the 'view after exporting' option? Feel free to try and duplicate the issue, let me know your results
