DPI

• DPI is a measurement of printer resolution indicating how many ink dots the printer can place in one square inch, the higher DPI the sharper image will get.
• Therefore, a printer that may have 72 DPI is a printer that can print 72 x 72 per square inch or 1,584 dots per inch. Dots Per Inch means number of dots in a printed inch.

PPI

• Short for Pixels Per Inch, PPI is the number of pixels per inch that makes a pixel image.
• Most commonly used to describe the pixel density of a screen (computer monitor, smart phone, etc…).
• The more pixels per inch the image contains, the higher quality of the image.
