A three-dimensional printing method and the decorative board and light box made therefrom

Abstract

This invention describes a method of stereoscopic printing and its application in decoration plate and light box. The stereoscopic printing method includes a substrate with concave and convex surface micro structures followed by printing with electron beam or UV light curable ink to retain the surface morphology after printing. The printing resolution should be between 5 and 20 times the density of concave and convex surface structure substrate is transparent, a high contrast image on a decoration plate or a light box can be obtained by integration of a reflective film or a back light unit.

Description

technical field

[0001] The invention relates to a three-dimensional printing method, which can be used for printing on various materials, and produces a visual effect of three-dimensional depth of field as the unevenness of the material surface changes. This technology can be used for three-dimensional printing on various objects, from Sheets are used for surface decoration of various furniture or commodities. When the three-dimensional printing is on a transparent lens sheet, it can be combined with a light source to become a light box. Background technique

[0002] Stereoscopic imaging technology can be divided into two categories: (a) the stereoscopic effect can be observed directly with both eyes; (b) the stereoscopic effect can only be observed by wearing auxiliary tools (for example: wearing special glasses□). Among them, the first type of stereoscopic imaging technology includes: parallax barrier stereo method (Parallax Barrier), also known as black line stereo metho...
