Lenticular book

A lenticular book[1] is a book that includes images created with lenticular printing technology. This special type of printing has given rise to books where the text is accompanied by pictures with 3D graphics. Pictures in lenticular books create the illusion of depth or transition depending on one's perspective. A lenticular book can also called a stereoscopic or 3D book. The first 3D lenticular book with a story was Lentibook Pirate Girl.

## Lenticular printing technology

Lenticular printing technology and stereoscopy is a complicated method of producing imagery that allows spatial visual perception. There are different types of lenticular printing, and over time the technology has evolved from simpler to more complex methods. Initially, it was accomplished with a combination of two alternating images. With this basic application lenticular printing can be found, for example, on children's rulers with varying images depending on the inclination of rulers and angle of view. Gradually the technology has improved and allowed the creation of images with stereoscopic 3D effects that are used in many applications, such as posters, billboards or postcards. This advanced technological stereoscopic 3D effect is often used in the production of lenticular books.

## Lenticular books

Currently, lenticular printing has mostly been used in children's' books. Over time the printing technology has improved, allowing more varied and detailed images with increasingly complex effects. The use of 3D images in educational material is hoped to increase attention and comprehension of the text. Although the process is expensive, in terms of both cost per page and technology required, lenticular book printing has seen considerable use in the Czech Republic, due to the country's long tradition of lenticular manufacturing. The aforemention Lentilbook Pirate Girl, or Pirátka Kačenka is a Czech product.
