The PRINTING United Alliance Glossary of Terms serves as an excellent industry terminology resource. It is the language by which we all communicate, without it universal understanding would be impossible. Language and our ideas about how it is interpreted change rapidly. PRINTING United Alliance is aware of this and continues its effort to keep our constituents well informed about changes to the increasingly complex industry terminology. The definitions are for general reference only. Usage may vary between companies, individuals, or national and country customs. The information presented is as accurate as the authors and editors can ascertain and PRINTING United Alliance assumes no responsibility for the use of information presented herein.
The number of lines of halftone dots per centimeter or linear inch.
Artwork, originals or printed matter consisting of lines or solids or dark and light tones.
Subsampling to reduce the number of raster lines in an image by dropping every nth raster line from the scan. See also pixel dropping.
A ruler scaled in picas and points, but may also include inches and agate measurements, used by printers.
A photographic image that is composed of fine, solid lines or dots or other shapes, all solid black or color, with no graduations of tones as in a continuous tone image.
Creating more raster lines than are actually scanned by replicating every nth raster line from the scan. See also pixel replication.
An exposure, made in a camera, of line art copy or larger solid areas that are not graduated in tones.
The rate of travel of a substrate through a production line such as a drying or curing line.
A form of halftone made up of parallel lines instead of dots.
The actual width of a screen printed line measured very accurately and precisely in mils; also refer to conductor width.

(1) Thin markings denoting the contour of a design; (2) Parallel rows of halftone dots.
Lines per centimeter (LPC)
The number of dots per centimeter. (As a general rule the higher the dot count per centimeter, the higher the resolution).
Lines per inch (LPI)
The number of dots per inch. (As a general rule the higher the dot count per inch, the higher the resolution).
Face sheet or cardboard stock where the face or surface material differs from the center core laminations.
Lining gold (lining palladium) (lining platinum)

Liquid bright gold
A complex organic resonate of colloidal gold, fluxes, organic resins, and organic solvents suitable for application to glass or china, where high temperature firing develops a bright mirror finish.
A chromographic process for analyzing liquids and solutions where the moving phase is a liquid.
Liquid crystal display (LCD)
Type of electronic changeable copy sign using liquid crystals that become opaque or clear when exposed to a controlled voltage.
