I have a white drop shadow with a text box placed in it, set on top of a Photoshop image. The drop shadow transparency image box stretches across to the joining/facing page. When I create the pdf for each page, the part of the transparency image box that is created in the bleed/gutter and that stretches into the facing page comes out as lo-res (118 dpi). The rasterized/tiled images that were created when flattened within the page are 300 dpi.
Why is the bleed and facing page image(s) coming out lo-res?
