What file format should I use for lenticular card printing?

Lenticular printing layers several images so they animate or shift as the card tilts, which means each frame of the effect has to be supplied as its own clearly named file. Consistent naming is what lets the printer stack the frames in the right sequence and align them under the lens.

• Format: supply print-ready PDF files for every frame and for the back.
• Naming for flips: name each frame in sequence, such as flip1, flip2, flip3, so the animation order is unmistakable.
• Back file: label the reverse side clearly as back.
• Consistency: keep every frame the exact same dimensions and alignment so the images register correctly under the lenticular lens.

Clear, sequential naming avoids misordered frames and keeps the flip or depth effect sharp.
