Lenticular signs are made by forming vertical solid shapes usually out of powder-coated aluminium, with graphics applied to the opposing surfaces to create the illusion of movement or depth when viewed from different angles.

Lenticular signs are often used in marketing materials such as posters, packaging, signage, and promotional products. They can be used to create a variety of effects, including:

• Flip effects: One image changes into another
• Animation effects: Such as winking eyes
• 3D effects: Offsetting layers at different increments

Lenticular signs are also known as "flickers", "winkies", "wiggle pictures", and "tilt cards". Here are some tips for creating lenticular signs:

• Use high-resolution images with at least 300 dpi
• Avoid complex animations, difficult-to-read fonts, and white or light-colored backgrounds
• Work with a printing company that has a history of producing quality prints

The quality of a lenticular sign depends on how the images are processed before production.
