We can work with most image formats, but please feel free to contact us if you have questions or need assistance. We accept .ai, .cdr, .eps, .psd, .jpg, .png, .gif, .tif.  Be sure to convert all fonts to paths or curves.
To avoid any delays, please be sure your images are large enough that when re-sized to a printable size they will not pixelate.
If you have questions about this, please contact us.
