How do I prepare files for 3D lenticular posters?

Lenticular posters are built from multiple images that get interlaced under the lens, so file prep differs from a flat poster.

• Supply a separate file for each flip, frame, or image layer
• Keep every layer at the same dimensions and resolution
• The images are interlaced during production to create the motion or 3D effect
• Ask 4OVER4 support for the exact format and layer specs for your project

Clean separation between frames matters most: the sharper each source image, the crisper the final lenticular effect.
