DPI

DPI refers to a measurement of how many tiny dots of ink a printer can place in one inch of paper, the higher DPI is, the sharper and more detailed the printed image appears. For example, 300 DPI is the standard for high-quality printing like books, photos, and magazines. Lower DPI such as 72 or 150 might look fine on the screen but it is going to be blurry or pixelated when printed.
