    Why is InDesign creating PDFs that display negative images in some browsers?

    alisonnnnn Level 1

      I've been laying out a single-colour newsletter using InDesign (Mac) for many years. The photos in it are saved as greyscale and tagged Pantone 343u. The newsletter goes to print as a PDF and I create a web version by exporting as Adobe PDF (interactive) without any problems.


      The last issue I produced using InDesign 2017 ( build). It has been pointed out that the interactive PDF displays the photos as negative images in some browsers - Firefox on Windows 7 and 10, as well as the PDF viewer that Slack app uses.


      Can anyone tell me what I can do to stop this happening?
