I have made a banner in Illustrator and I've uploaded a jpeg photo as part of it. I'm worried that once it is printed at a much larger scale, I will lose all of the quality of the image. How do I edit the photo so it retains its quality?
Right now the entire banner is 1200 x 575 pts with 300 ppi. I have sharpened the image in Photoshop, but I'm wondering what else I need to do.
