What are the preferred file types and size requirements for logos?
Your signature and logo should either be a JPG, JPEG or TIF file. The logo should be at the highest quality possible, 72 dpi is good for viewing on your computer, but the quality should be higher for printing. If you cannot find a high quality logo, you may choose to leave it off the greeting card, or use the logo anyway. The closer to 300 dpi the better. The logo should be at least 1 x 1 inches.
