What are the best practices for how 3D posters are made?

A convincing 3D lenticular poster comes down to clean source art, smart layering, and a proof before the full run. The lenticular lens splits your image into angles, so the file has to be prepared with that in mind.

• High-resolution files: start at 300 DPI or higher so detail holds up through interlacing.
• Separate your layers: split the design into distinct foreground, midground, and background layers for real depth.
• Bold, saturated color: strong contrast reads better through the lens than subtle gradients.
• Mind the depth zone: keep fine text and small type out of the deepest 3D layers so it stays legible.
• Always proof first: order a lenticular proof to confirm the interlaced image lines up with the lens pitch before committing to a run.
