Definitions

• the present invention in some embodiments thereof, relates to lenticular printing and, more particularly, but not exclusively, to lenticular image articles and methods for reducing or eliminating banding artifacts in lenticular printing products such as lenticular image articles.
• Lenticular printing is a process consisting of creating a composite interlaced image by interlacing various images, and attaching it with a lenticular lens arrangement, such as a sheet, to form a lenticular image article.
• a lenticular lens arrangement such as a sheet
• the lenticular printing can be used to create a dynamic image, for example by offsetting the various layers at different increments in order to give a three dimension (3D) effect to the observer, various frames of animation that gives a motion effect to the observer, a set of alternate images that each appears to the observer as transforming into another.
• 3D three dimension
• One of the most common methods of lenticular printing which accounts for the vast majority of lenticular images in the world today, is lithographic printing of the composite interlaced image directly onto lower surface of a lenticular lens sheet.
• banding In order to improve the clarity of the effect of the dynamic image to the observer, some artifacts may be reduced.
• One of the reduced artifacts is banding.
• the banding artifact is formed when transition starts in several places and progresses from each starting point towards the next, giving the impression of several curtains crossing the visual.

These separator images are created, for example, as an averaging of the input images. It should be noted that the use of separator images increases the mixing among views and hence increases ghosting and blur and provides only a partial reduction in the banding artifact.
