PDF Export vs Distiller Resolution Issue - Adobe Acrobat Macintosh

Thanks for responding. Jon: Your comment about exporting from InDesign to generate a PDF. It sounds like the overall image quality is "downgraded" some what by going from InDesign > Postscript > PDF as compared to just exporting to PDF from InDesign no?

    Gene: The image quality does look better when sending data as "All." So why is the "Optimize Subsampling" option the default and available? Is it not appropriate for commercial printing? Unknowingly, I think I have been send PDFs with that default but none of the printers have said anything. The printed pieces generally look good.

    In fact typically, the image resolution and quality of the least
    affected since they are static objects as such.

    The type of quality which can be lost can be layers (OCG), ICC profiles,
    trnsparency, hyperlinks, bookmarks, doent structure as an example.
    Although not all print related - it's interesting to know's going on
    through the conversion.

    Jon,

    I am not sure what you meant by static objects. Please elaborate.

    As for the quality being lost. Were attributing the lost to exporting to PDF from InDesign or generating a PDF via Distiller?

    Thanks.

    images with a specific resolution and indeed, colour space such as
    DeviveCMYK (as an example)

    Not really, more metadata objects as such - the upper most layer in a
    PDF, layers, annotations, links etc., etc
