Kissprint
The use of just enough impression to allow ink to transfer from the blanket to the substrate. Too little impression will cause the image to appear to be cloudy or have breaks. Too much impression will cause dot gain and/or the lenticular sheet to stretch or be squeezed and augment. < back >


Lamination
The process of adhering a preprinted media to the lens sheet. It is commonly used to apply both photographically imaged and digitally outputted images to the lens sheets. < back >


Lens Count
The number of lenticules-per-inch (LPI.) < back >


Lens Sheet
A sheet of transparent plastic material that has been extruded, cast, or embossed with an array of identical parallel lenses. < back >


Lenticular
A specialized printing process that allows depth, motion, or a little of each to be shown in a flat sheet of plastic. The effect is created using lenticules in the plastic sheet that serves as a decoder for the image that is printed behind it. < back >


Lenticule(s)
A single (or multiple) lens in a lenticular sheet. < back >
 

LPI
Lines-per-Inch. In the lenticular process, this would also mean "Lenticules-per-Inch." < back >


Morph
A lenticular effect that begins with one image which is then transformed in stages to a second, perhaps unrelated, image. < back >


Motion
A lenticular effect that utilizes selected highlights of frames from animated illustrations, video, or film originals. The frames are displayed to the viewer one sequence at a time. The viewer is given an impression of movement from one frame to the next. < back >


Narrow-angle Lens
A lenticular lens sheet with a viewing angle between 15-30 degrees. Narrow-angle lenses work best for 3D effects. < back >


Parallax / Parallax Shift
In a 3D image, the phenomenon where objects in a scene seem to shift relative to one another as the angle of view is changed. Objects closer, or in front of the keyplane, will be opposite objects behind the keyplane. < back >


Phase
The number of discrete frames of a lenticular image. For example, a three-phase "flip" has three images (or frames) of information. < back >


Pitch
The exact count, or number of, lenticules-per-inch (LPI.) < back >


Mechanical Pitch
The exact, and true, physical pitch of a lens. (Although a lens manufacturer may label their lens to be a 75 lpi, the true mechanical pitch will not be exactly 75 lpi. This is due largely to the fact that there are slight variances that take place during the extrusion or manufacturing of a lens.) < back >
