DPI

  1. Short for Dot Per Inch, DPI is a measurement of printer resolution indicating how many ink dots the printer can place in one square inch, the higher the DPI the sharper the image. Therefore a printer that may have 600 DPI is a printer that can print 600 x 600 per square inch or 360,000 dots per inch. Because all printers print by a series of dots, printers that do not have high DPI ratings may encounter jaggies. Resolution Enhancement and other edge enhancements help correct the appearance of jaggies with printers that support this technology.
  2. DPI, or Dots Per Inch, is also used to determine an image resolution.
