What are the best practices for 3D lenticular cup design?

Lenticular artwork lives or dies on file quality and contrast, because the lens splits your image into interlaced strips. Set the specs up correctly before you design, not after.

• Start with high-resolution source images, generally 300 to 600 DPI.
• Use bold, high-contrast compositions and avoid busy backgrounds that muddy the effect.
• Increase color saturation by roughly 10 to 15 percent to offset lens diffusion.
• Decide your effect early, since flip, animation, or 3D depth each change the file requirements.
• Always request a physical proof before approving a full production run.
