Definition of lenticular term

Pitch
It refers to the number of lenticules per inch (LPI). The standard is 75lpi. The figure gives us some idea of how many lenticules could be found in inch but the exact figure will vary from sheet to sheet and some from pallet to pallet. It is important to carry out the process called "pitch test" to find out which is the actual figure before printing as incorrect matching of lenticular sheet with the interlaced images will result in poor lenticular printing result which is named as "incomplete changing".
