The d.p.i. is a measurement of detail. A digital image is broken down into tiny dots. As registered onscreen, theyâ€™re known as pixels. The more pixels there are, the more detail and clarity is in the print. Thus, the higher your d.p.i. (which also means the higher your resolution), the more stunning your finished print will be when doing significant enlargements. Also referred to as p.p.i. (pixels per inch).
