Lenticular Printing

Lenticular Printing

Converting a 2D images to 3D

An undesirable result of lenticular printing which happens when more than one image is visible at certain viewing angles. Possible causes are: images on the same lenticule (lens) have too much color contrast, poor registration, mismatched pitch, or too many frames.

Technically speaking, rendering and printing a lenticular animation effect image on a lenticular sheet are less difficult than a 3D effect image. However, from the designer's perspective, it is much more difficult to design a ghosting-free animation lenticular effect image than that of a 3D effect image.

In fact, the most common cause of ghosting is when “images on the same lenticule (lens) have too much color contrast”. Color contrast is the most difficult design challenge for the graphic designer who is not used to designing artwork for lenticular printing.

The main focus of this article is to address the ghosting challenge in lenticular printing and introduce a simple method called “Finger Finding” to detect potential ghosting problems.

It concludes by discussing ways to avoid potential ghosting issues in lenticular printing.
