    I have a placed a square photograph with a drop shadow. All is well until I rotate it. It looks fine in InDesign but when I export to Press Quality PDF I get a strange effect: A grey “ghost” square of flat shading appears on the area where the square would have been had I not rotated it. The drop shadow is fine but this “effect” is an additional piece of shading separate from the drop shadow. If I decrease the percentage of the drop shadow, the grey shading in the square also decreases but is still obvious. Is there something I need to check when outputting the PDF? The “ghost square” does not appear on low-res PDF. The image plus drop shadow looks fine on the InDesign page.

    Your help much appreciated.

    I have not experienced this problem myself but am wondering if it could be solved by adding the drop shadow AFTER you have rotated the photograph?

    Thanks so much Furry, that was worth a try but didn't work.

    I've noticed two things since: That the “ghost” square does not simply cover the area of where the initial square was but that it covers the area that the square and the drop shadow would cover (had they not been rotated). Scouring the Net I've found similar instances of ghosts appearing when people printed out documents. In my case, the ghost is only visible on the high-res PDF, not on the InDesign document and not visible when I do an overprint preview (View >> overprint preview). I don't have a printer here so can't check it if would print.

    Incidentally, the photo is placed on a CMYK background with a 30% tint.

    Thanks again
