I apologize if this has already been answered. I am an Illustrator beginner to start. I have been making some dvd covers in illustrator and have come across a little issue. Some elements are extremely blocky/pixelated when printed even though they are not that way in the illustrator interface. Some are elements from after effects that I rendered out as PNG or Photoshop images. Others are some photos taken with a Canon 5D MK2. Even though the pics are huge and perfect image quality they still print pixelated. The only things that turn out sharp are the elements I add in illustrator such as text etc. I know there must be something I am doing wrong, process wise. I know Illustrator is huge and can be complicated and I don't know that much about it. Any help would be appreciated. Thanks in advance!
