I am trying to take photo, remove the background and print to pdf to send to local printer to have printed on vinyl banner. When they open it up they tell that the photo is made up of gradient lines instead of a solid photo. I am doing an edit bitmap and going through photopaint to cut out the background in image lab. How can I accomplish this so that when the printer opens up the image it is a solid image and not an of gradient lines?? Is it an issue of how it is being saved maybe??
