History and present
The first pioneer of this technology was in 1692 French painterG. A. Gois-Clair. He mutually interchanged strips of two paintings and put it behind a grid of vertical wooden sticks with same span. From right side was seen one painting and the other one from left.
Photographic methods were implemented to this technology independently from each other by Jacobson and Berthier around 1896.
The first application was in 1903 by American Frederick E. Ives and later by Estenave in France in 1906. Ives named it „Parallax Stereogram“ thereby he explained that instrument for stereoscopic viewing is placed on the image and not on eyes – barrier grid was created by strips of hiding paint. 
Disadvantage was visibility only from narrow range which was largely eliminated by adding more perspectives to the original two. This was first proposed in January 1915 by Clarence W. Kanolt and this method named „Parallax Panoramagram“. Barrier methods gradually disappeared with start of industry-made plastic lenticular foils.
March 3, 1908 physicist Gabriel M. Lippmann replaced opaque links by series of lenses. He used little konvex spheric lenses called integral.
In late 20. of past century Herbert Ives and his coleagues simplyfied his idea of thin konvex lenses known as „lenticuls“.
The first truly lenticular images were produced in thirties by Victor Anderson`s company Vari-Vue. In late fourties of past century produced millions of prints each year. 
Mass production became reality when in 25.2.1964 magazine Look published first „parallax panoramagram“ with 3D image printed by offset machine laminated with thin layer of plastic. Process known as „Xograph“ was developed by Arthur Rothstein and Marvin Whatmore from Eastman Kodak. Coloured print again for Look followed in 7.4.1964.
Creating 3D images by digital interlacing of computer-generated 2D images was firstly demonstrated by Japanese Jutaka Igarashi, Hiroshi Murata and Micuhiro in 1978.
Digital interlacing of colour images with high resolution was first proposed in 1990. National Graphics became a pioneer of direct offset printing on reverse side of the lenticular foil in 1994. This method was patented as „Extreme Vision“. 
In 2002 patented thin lens with high resolution Crystal lens (200 lpi, thickness 0,007´´).
The technology has spread only when decreased price of the plastic (PVC) and new material PETG has been discovered. To mass production also contributed progress in commercial print.
In late 80. computers became usual in polygraphy and along with modern lenses revived interest in efficient promotion tool. At first lenticular images speaded as attractive novelty alone, today it is used mainly as marketing tool.
