What size and resolution should my logo and other graphics be?

Bigger is not necessarily better. Since the cards are printed at 300 DPI ( dots per inch), there is no need to create huge high resolution graphics. Using a program such as Adobe Photoshop, you can compress and save your graphic files before uploading them to IDs Now. Too much compression results in a poor image, while not enough can result in a large graphic file size. Print some locally and find the balance. Supported file types are: WMF, BMP, JPG, GIF, PNG, TIF & PCX.
