Making a book to be printed. Imported many images cropped to circles in Photoshop, all at 300ppi or greater. They look fine in In Design, but when I export to a PDF the edges of the circles show strange burrs at the top, bottom, left and/or right. These need to print cleanly. Help!
Try printing them on your desktop printer. Sometimes, by nature of pixel-based screens, Acrobat doesn't show images and graphical elements as cleanly as they'll actually print.
