DPI stands for dots per inch and indicates how many pixels (dots) there are per inch (2.54 cm) in an image. The higher the number of DPI, the sharper your image will print.

When printing, high image quality is important, because a blurred or blocky image quickly looks unprofessional. Therefore, we recommend a minimum resolution of 150 DPI, and preferably 300 DPI for all your printing.

Note that a low DPI may look good on the screen, but in print the image will become blurry or grainy.
