DPI, which stands for "dots per inch," is a measurement used in the field of digital imaging, particularly in reference to the resolution of images. It quantifies the number of ink dots or pixels that can be present per linear inch in a printed or displayed image. DPI determines the level of detail and clarity in printed or digital visual content.
In printing, DPI refers to the number of dots of ink that a printer can produce within a one-inch span. A higher DPI means more dots are placed in each inch, resulting in a denser image and finer level of detail. For example, a printer with a DPI of 1200 can place 1200 dots of ink horizontally and vertically in one square inch, resulting in a highly detailed image.
In digital imaging, DPI refers to the resolution of images displayed on screens or monitors, such as computer monitors or mobile devices. It measures the number of pixels displayed per inch. A higher DPI value means more pixels are present, resulting in a sharper and more detailed picture.
It is important to note that DPI is different from PPI, which stands for "pixels per inch." While DPI refers to the physical printing or output resolution, PPI is used to describe the resolution of images on digital screens. However, the terms are often used interchangeably, especially in casual usage.
