Vector versus Bitmapped Image
When zoomed in, the bitmapped image appears jagged, whereas the vector graphic appears clear and crisp. You will want to keep this in mind when using images. To get the highest quality we recommend using vector images.
CMYK Color Mode
It is important that you convert your files to CMYK, since this is the only color mode that we accept for printing. Any other color mode will not produce optimal printing results.
