What is resolution?

Resolution is also known as dpi (dots per inch) or ppi (pixels per inch). It indicates the number of colored dots or pixels that make up one image. The higher the dots per inch/pixels per inch, the greater the resolution and the clearer the resulting final print will be.

LPI, or lines per inch, is a measurement of resolution that uses a halftone screen. LPI measures how close together the lines are in this halftone grid. The higher the lines per inch (or the closer the lines are together), the better and clearer the image will be. In order to determine the appropriate image resolution needed for print, the combination of your printer’s DPI and the required LPI must be observed. Whereas the DPI determines the number of dots per inch, the LPI is also needed in order to determine the frequency of the lines containing the dots, per inch of the halftone grid. Once these two elements are calculated, the correct resolution can be determined. The image usually must have 1.5 to 2 times as many dots per inch as lines per inch.
