DPI (Dots Per Inch, dots per inch) is a unit of measurement for dot matrix digital images, which refers to the number of sampled, displayable or output dots per inch of length.

DPI is a unit of measurement for the resolution of devices such as printers and mice. It is one of the main parameters to measure the printing accuracy of the printer. Generally speaking, the higher the DPI value, the higher the printing accuracy of the printer.

DPI refers to pixels per inch, which is the scanning accuracy. The lower the DPI, the lower the resolution of the scan. Due to the influence of network transmission speed, the pictures used on the web are all 72dpi, but this parameter cannot be used for developing photos, it must be 300dpi or higher 350dpi. For example, if you want to develop a 4*6-inch photo, the scanning accuracy must be 300dpi, then the file size should be (4*300)*(6*300)=1200 pixels*1800 pixels.
