DPI

Stands for "Dots Per Inch." DPI is a measurement of print resolution that describes how many individual ink dots a printer can place within one inch of paper. The higher the DPI, the more detail and sharpness of a printed image.

For example, a 600 DPI printer can print 600 dots horizontally and 600 dots vertically within a single inch — a total of 360,000 dots per square inch (600 x 600). Modern printers may support 1200 DPI or more, producing smoother gradients and finer detail.

DPI affects the quality of printed photos, graphics, and text. Professional-quality printing typically uses images prepared at 300 pixels per inch (PPI) to ensure sharp results on paper.

NOTE: It is important to understand that DPI refers specifically to printed dots — not screen pixels (PPI). While the terms are often used interchangeably in casual conversation, DPI technically measures printer output, not display resolution.
