The Principle And Viewing Method Of Lenticular

2024-07-09

1. What is a lenticular?

 

  The term Lenticular is derived from the word lenticules. A virtual image is printed and interlaced on a plastic material with tiny grooves, also known as lenticules. The finished product is an image that gives off the illusion of movement when viewed from a different angle. Lenticular printing is a technology in which a lenticular lens is used to produce images with an illusion of depth, or the ability to change or move as the image is viewed from different angles. This technology was created in the 1940s but has evolved in recent years to show more motion and increased depth. Originally used mostly in novelty items, lenticular prints are now being used as a marketing tool to show products in motion.

 

 

2. How to view a lenticular:

 

2.1. What is lens direction and how does it affect the lenticular print?

 

  The lens direction is the direction that the lenticular print would need to be moved in to view the lenticular effect. For example, lenticular prints with the 3D depth effect, the lens direction goes up and down. For lenticular prints with the Animation effect, the lens direction goes from side to side.

 

2.2 Different lens direction for different effects

 

① 3D effects

 

  • In a lenticular effect, the lines of the lenticular must be vertical if the effect is to be rendered in 3D.

 

② Flip Effect

 

  • If it looks like a different picture is being switched, and the effect is been seen by flipping left and right, we call this is a left-right change. In this case, the lenticular lines must be vertical. Due to the limitations of the lenticular imaging principle, it is recommended that two changes is the most suitable, as more than two changes are prone to ghosting.

 

  • If the 3D product is turned up and down, the lens direction must be horizontal.
