What are the best practices for 3D lenticular postcard trends?

Great lenticular postcards come down to file prep and choosing the right effect for your content. Because the lens magnifies every flaw, start with clean, high-resolution artwork and test before you commit to a full run.

• Use 300 DPI or higher source images so the effect stays crisp under the lens.
• Build strong contrast between layers for maximum depth and pop.
• Keep fine text off the lenticular side, where small type can blur.
• Match the effect to the message, whether that is depth, flip, animation, or morph.
• Order a proof before full production to confirm the effect reads sharp.

Nailing the file interlacing is the single biggest factor in the final result, so budget time for proper prep or bring in a designer who has done it before.
