Resolution - also known as DPI (Dots per Inch for printer) or PPI (Pixels per Inch for the screen). is the number of dots that fit horizontally and vertically into a one-inch space.
Generally, the more dots per inch, the more details captured and the sharper the resulting image.
Note: DPI is not = PPI.
SCREEN PPI vs PRINT DPI
The terms Dots Per Inch (DPI) and Pixels Per Inch (PPI) are commonly used interchangeably to describe the resolution of an image.
However, the terms do not mean the same thing and there are distinct differences between the two:
DPI refers to the number of printed dots contained within one inch of an image printed by a printer.
PPI refers to the number of pixels contained within one inch of an image displayed on a computer monitor.
