Benefits of technology
This approach enables the creation of personalized three-dimensional products with improved viewing angles, high-resolution printing, and the ability to display complex effects, such as motion and transformation, while avoiding moire patterns.
Problems solved by technology
In this case, the lenticular screen that has the plurality of semi-cylindrical lenses serially arranged on the top surface of the plastic sheet gives the three-dimensional effect just to the left and right sides with respect to the length direction of each lens, but does not give any three-dimensional effect to the upper and lower sides thereof, such that there is a defect in that the viewing angle for the three-dimensional image is limited.
At this time, there occurs a problem that since the conventional plastic sheet does not have any high resolution due to the embossing effect of the lenses seen through the lens layer, the printed screen cannot be vivid and clear.
On a general offset printing screen, moreover, numerous dots constituting the printed screen are refracted on the lens layer to cause the generation of moire patterns or dizzy illusion due to the interference of the dots, such that more vivid three-dimensional screen cannot be provided.
With the conventional three-dimensional plastic sheet processed by means of the offset printing, therefore, a simple pattern of three-dimensional image should be displayed through one-color printing, which makes it difficult to display a three-dimensional effect through four-primary color printing or special effects (for example, two-way transformation, motion, and morph effects) in a lenticular technique.

Embodiment Construction
[0043]Embodiments of the present invention may be understood more readily by reference to the following detailed description. It is to be understood that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting.
[0044]As used herein, the singular forms “a,”“an” and “the” include plural referents unless the context clearly dictates otherwise. Thus, for example, reference to a “convex lens” includes embodiments having two or more such convex lenses unless the context clearly indicates otherwise.
[0045]Ranges can be expressed herein as from “about” one particular value, and / or to “about” another particular value. When such a range is expressed, another embodiment includes from the one particular value and / or to the other particular value. Similarly, when values are expressed as approximations, by use of the antecedent “about,” it will be understood that the particular value forms another embodiment. It will be further und...

Abstract
A method of making a personalized three-dimensional product is provided. The method includes identifying a personal graphic. A sheet is provided having a convex lens layer with an array of identical semi-spherical convex lenses formed on the top surface thereof wherein each convex lens has a focal distance, a transparent plate layer disposed at a bottom surface of the convex lens layer and having a thickness corresponding to the focal distance of each convex lens, and a focal distance printed layer disposed at a bottom surface of the transparent plate layer. The personal graphic is applied to the sheet in a non-focal relationship relative to the convex lenses.
Description
CROSS REFERENCE TO RELATED APPLICATIONS [0001]This application claims priority to U.S. Provisional Patent Application No. 61 / 080,800, filed Jul. 15, 2008, which application is incorporated herein by reference in its entirety.FIELD OF THE INVENTION [0002]The present invention relates to methods and assemblies for three-dimensional products, and more particularly, to a personalized three-dimensional product.BACKGROUND [0003]Generally, a three-dimensional plastic sheet is formed of a lenticular screen that has an array of semi-cylindrical lenses each having a pitch of about 0.5 mm formed on the top surface of the sheet. In case of a three-dimensional photographic printing, the images of an object seen by left and right eyes are each printed on a sheet of lenticular screen, thereby obtaining a three-dimensional image where the object looks like floating in the space or going away into the space when seen through the two eyes.[0004]In this case, the lenticular screen that has the plurali...
