A vector is the very best. These files have suffixes like .ai, .pdf, .eps, .svg. We do not work with Coreldraw files.

A jpg or a png file has to be at least 3 mg in size when closed. When the file is open,  it should be 13″ wide and have the resolution of 200 to 300 dpi. The danger is if we use a low resolution file, it will be blurry when printed on the back.

If you require a sleeve design that use elements from your logo, we will require the vector version of your logo, if at all possible.
