Description

Double-sided stereoscopic printing method

The invention provides a printing method for double-sided stereoscopic imaging, in particular to a printing method in which two surfaces of the printed material respectively exhibit different three-dimensional image development, and the two surfaces of the transparent printed material are used to respectively print different patterns and structures of different parameters. Graphics, two-sided viewing can display different stereoscopic image display effects.

Press, the cover of various documents, materials or notebooks, back cover or internal mezzanine pages, folders, folders, etc., often have many design artwork or image, texture generation, in order to present different stereoscopic effects, aesthetics, when used It can increase the fun effect, and it is gradually popular with the public, and various images, patterns, patterns, etc., can be applied to books, documents, etc. through printing, list machine printing, plotter drawing, etc. Medium, daily necessities, clothing and other objects; however, the surface decoration effect of the general plane pattern or image is usually monotonous and ordinary, and the resulting 2D image visual effect is not real, not distinctive. It is impossible to highlight the special point of the surface decoration image, and it is less likely to attract attention; therefore, the generation of stereoscopic images (3D), patterns, lines or fonts can be caused by the combination of images and grating plates. The stereoscopic visual perception of the pattern or image presents different stereoscopic aesthetics, while the Lenticular is made up of a number of slender, straight-line plano-convex lenses (Plano-Convex Lens). The transparent sheets formed side by side are products made by the principle of optical refraction, and the images or patterns on the bottom of the transparent sheet must be processed through precise and accurate techniques with the grating plate, that is, the processed image or pattern is passed through the transparent sheet. Refraction, you can view the stereoscopic imaging effects such as changes, movement, deformation, and zoom of the view or image, and apply it to Flips, Motion, 3D stereoscopic effects, etc. The way in which stereoscopic images or patterns are displayed can only be used for simple viewing and does not produce other additional visual effects.

In general printing operations, the plate-making operations of the screens that are often applied must be made by computer to produce optical component images, and then the optical component images are output to the screen, so that a plurality of images with overlapping optical components are generated on the screen. Image, texture, typeface or shape, etc., so that the pattern printed by the printing operation, etc., will produce a stereoscopic (3D) image perception; however, the stereoscopic image currently produced through the printing operation is limited to one-sided Printing, can not form a perspective effect, can only be viewed from the front, and the stereoscopic perception is limited.
