Hi Scott, Personally I don't use Illustrator. I use Photoshop CS for intricate work and Elements for quick jobs. For jpg's there is a general rule to never overwrite the image, delete it first then save, but never "replace". Not abiding by this rule can result in a lower quality output. Also, in Photoshop it, for whatever reason, is better to flatten the layers before saving as a jpg, I don't know why but my final quality seems to better that way. When you save as a jpg where are the seams being a problem? What specifically are turning out bad? Tim
