I am getting black pixals that show up around my photo when I export to PDF High Quality Print and print. Some of my other photos have the pixals show up when I open them up in preview but they are white. How are you able to get rid of these? Any help is much appreciated.
Have you taken an image of this with a white background and used the 'Magic Wand' tool to remove the Whites?
In Photoshop, can you put this image in 1 layer and create a new layer underneath this layer and fill it with black? Can you then see the white pixels?
If you do, the problem is 'white pixels' are present in your source image itself.
