Single color printing method for colored three-dimensional image

Abstract

The invention discloses a single color printing method for a colored three-dimensional image. The method comprises the following steps of: recombining red-green-blue (RGB) three color components of a three-dimensional image to form a single color image; outputting the single color image to a printing plate; and overprinting to an RGB color plate to form a colored image which presents a distinct clear three-dimensional image under the irradiation of a backlight source, wherein the RGB color plate comprises periodically-distributed red (R), green (G) and blue (B) lines and overprinting marks. By the three-dimensional printing method provided by the invention, three-dimension obscuring and giddy feeling which are caused by inaccurate overprinting during four color printing are prevented, the independence of pixels is ensured, the vividness of colors is improved, the stereoscopic impression and the definition of pictures can be substantially improved, and the requirements of low cost and batch production of three-dimensional lamp box sheets are met simultaneously.

Description

Technical field: [0001] The invention belongs to the technical field of printing, and relates to a monochromatic printing method of a color stereoscopic image. More specifically, it relates to a method for printing black and white images on primary color plates to realize color stereoscopic display. Background technique: [0002] The printing of lenticular three-dimensional pictures mainly includes direct printing and stickers. Direct UV printing of stereo images on the back of the lenticular lens is called direct printing, which has high efficiency and good effect, and is very suitable for gratings with a thickness below 0.6mm; printing the stereo images on coated paper, and then compounding them on the back of the lenticular lens is called stickers , the effect is good but the efficiency is low, suitable for thick gratings with a thickness above 0.6mm. The screen screening of three-dimensional printing directly borrows the screen screening technology of the plane, such a...

Problems solved by technology

Three-dimensional printing requires cmyk four-color to have extremely high overprinting accuracy, otherwise it will affect the three-dimensional effect and clarity of the three-dimensional picture, so the usual three-dimensional printed matter is small and medium format, and the three-dimensional effect cannot be designed too large

[0004] Patent No. 200710079378 discloses the high-definition lenticular 3D image, which solves the three-dimensional effect, clarity and viewing comfort of the 3D image. We apply the same idea to 3D printing, bypassing the bottleneck of four-color 3D printing That is, the problem of low overprinting accuracy, while solving the cost and mass production problems of three-dimensional light boxes
