Hey guys, I need help. I have an image that I need printed on a banner either 4x6 or 3x8. The image is a 2048x1010 pixel .png. The banner maker is requesting that I send him a high res vector copy in .eps format that is at least 300DPI. I created the image in pixelmator and pixelmator does not support .eps format. I also do not know how to increase the DPI. Any help is appreciated.
