What is the difference between DPI and LPI?

DPI or Dots Per Inch is a measure of the resolution of an image in a document as measured by however many pixels are contained within a 1 inch square of the image. Thus the more pixels per inch, the greater the resolution.

LPI or Lines Per Inch is generally a measure of the output resolution of the output device printing the image or document. LPI can determine the what the relative DPI of an image being printed should be. For example our platesetter is capable of production resolutions of or greater than 150 lpi at 2400 dpi. For this resolution, an image must be at least 300 dpi, yet for an output resolution of 85 lpi at 1200 dpi, an image resolution of only 150 dpi would be required.
