Subsequently, What is 3D lenticular printing? In simple terms, lenticular printing is about creating images that move or show depth using 3D illusion. Lenticular means relating to lenses which are called lenticules. These lenticules are made of plastic lenses that create the illusion of dimension in-depth imaging and or movement.
What is a negative lenticular lens?

What is the difference between lenticular and hologram?
Do you know the difference between lenticular printing and holograms? Lenticular printing is a special print process giving images an illusion of depth or motion when viewed from different angles. Holograms, on the contrary, demand for special light incidence, show only one single image and are monochromatic.
What are blended lenticular lenses?
The fourth type was a ‘blended lenticular’ lens. This is different from a conventional lenticular lens in that the corrective portion and the carrier portion are blended into one another to improve the cosmetic appearance.

What is a lenticular prescription?
Lenticular means the correction in the lens does not extend all the way to the outer edge of the lens. Since most people can’t see this part of the lens this has been a non-issue. This results in a lens that is about 50% – 70% thinner than a lens where the prescription extends all the way to the edge.
What are lenticular lenses made of?

Acrylic is known for its clarity, especially when used in thicker sheet products.

- Avoid type smaller than 14 points.
