The specific file formats will depend on your needs, but almost always include a combination of vector-based and bitmap-based graphics.  Vector-based images are scalable and editable – these are the files you will typically provide to the printer, and use to create business cards or signage.

Bitmap-based finals are of a specific width and height, and primarily used for display on websites and electronic documents.  If you need specific file formats, please request these directly from your designer.
