Lenticular Printing: and the Brave New World of 3D Printing

Lenticular Printing: and the Brave New World of 3D Printing

Lenticular is probably the best known printing technology with a 3D application.

Lenticular printing is a technology in which a lenticular sheet is used to let different images be seen by the left and right eyes so that the illusion of depth becomes possible on a 2D image.

The theory is simple and it is based on the principle of binocular disparity. To understand this, one can do a simple experiment by looking at an object using the left and the right eye separately.

You will find that the relative position of an object seen from the left and the right eye is slightly different. By emulating this binocular disparity using a lenticular sheet, one can see an illusive3D effect come alive.

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.
