Reply To: Crop image data to frames sometimes isn't, and it gets stranger…

I haven't seen this problem, but I have seen one that looks a little like the same thing (very slightly misaligned stroke). I was trying to mimic a Light weight in a font that didn't have one by adding a Paper-coloured stroke around the outside, with the Stroke Alignment set to Center. In the PDF, and when printed out on the office printer, the stroke didn't align properly with the character, so we ended up with what looked like a thin white letter sitting on top, and slightly to the side, of the black one. As with your problem, it looked completely fine in InDesign.

(In that case I found another font, which did have a Light weight, and looked sufficiently similar in the characters I was using. So I don't know whether the misalignment would actually have shown up on the press or not.)
