Lines Per Inch (LPI)

Abbreviation for Lines-Per-Inch. A unit for measuring output resolutions for lithography, screen printing and other output methods.

Lithography

A method of printing based on the dissimilar properties of two materials, typically ink and a modified water solution, where image carrying plates are treated so that the non-image area readily accepts the water solution which keeps the ink from adhering to those areas while the image area accepts the ink. Lithography is a unique conventional printing method in that the image and non-image areas of the printing plate are on the same flat surface.
