All About Lenticular Printing and The New World of 3D Printing
Lenticular
With a 3D application, lenticular is probably the best-known printing technology. When it first came into the scene, it was mainly about creating moving images or morphing one image into but these days the most popular use seems to be as 3D images.
How does it work?
To give a true stereoscopic image
for 3D lenticular, the same image needs to be seen by the viewer but from a
slightly different viewpoint with each eye. Into very thin strips the images to
be viewed are sliced and the two images interlaced with each other. The surface
of the soft lenticular sticker print mimics the length and
size of the images beneath.
Printing Considerations of 3D
Lenticular
By lenticular printing companies
two approaches have been taken; either to print straight onto the synthetic
paper or transparent lens material stock to which the lens is then laminated.
Since the key is accurate interlaced image registration to the lens in creating
a quality result but it is equally crucial to trace a supplier having good
experience of working with this material.
Typically 3D soft
lenticular printing processes print straight onto the smooth side of
the lens is commonly made from PVC or acrylic or polymers such as PET
(polythene). Now a day’s Flexo, inkjet, or screen printing are becoming
increasingly popular and as a continuous web it allows the lens substrate to be
fed into the press and for long-run applications, it increases the speed and
reducing the cost.
Artwork Considerations
To digitally interlace the picture the digital image is typically manipulated with a prepress software package and then it is ready for the lenticular Tpu printing process. All image files are created to produce a 3D image and as separate element layers in an Adobe Photoshop file, it is provided to the printer. Within the finished image 3D effects display depth information in relative terms between objects, so to accentuate the 3D effect a few objects within the image are advised.
