Problems solved by technology
[0004] There are two production methods for 3D stereoscopic pictures: one is printing. At present, the largest printing screen of printing machines at home and abroad is only about 600mm*800mm; the other is printing. The largest printing method is inkjet printer, which can print hundreds of Square, but because 3D stereoscopic pictures have extremely high requirements on the accuracy of image formation, it must be measured with four decimal places. The printer’s movement accuracy is 0.01mm, and the ink drop accuracy needs to reach 6 picoliters. Ordinary printers cannot be used to make 3D stereoscopic pictures at all. , high-precision printing equipment has a limited format. For the current largest UV flatbed printing equipment, the largest single screen can only be printed to 2000mm*3000mm
[0005] If the market requires huge 3D poster advertisements, the maximum size of a single screen is limited by the size of the machine itself. If it exceeds the printing range of the machine, it must be printed in several parts and then spliced, which will cause too many spliced pictures to affect the overall appearance and quality. Three-dimensional rendering effect, and inaccurate measurement when cutting the finished product, it is extremely easy to cause loss of splicing patterns, inaccurate alignment, and picture misalignment

Embodiment Construction
[0021] see Figures 1 to 3 , the present embodiment adopts the existing flatbed straight printer 800, computer 600 and optical microscope 700, which specifically includes the following steps:
[0022] 1) Operate the computer 600, and divide the picture file into two image areas 100 and 200 of upper and lower A1 and A2 on the computer 600; and set the left alignment cross line 300 and the right cross alignment line 301 and Leave a blank area, and also set a left alignment cross 400 and a right cross alignment 401 above the A2 image area 200 and leave a blank area.
[0023] 2) Place the cut lenticular plate on the bearing platform of the flatbed straight printer 800, and after it is precisely aligned and fixed on the bearing platform, the image 500 of the A1 image area 100 and the image 500 of the A1 image area 100 are actually printed out. The left cross aligns the bit line 302 and the right cross aligns the bit line 303 .
[0024] 3) The grating plate obtained in step 3) is ...

The invention relates to 3D (three dimensional) stereograph printing methods, in particular to a raster plate seamless splicing type printing method for 3D stereographs. By the raster plate seamless splicing type printing method for the 3D stereographs, 3D stereographs out of fixed printing range of a machine can be printed on the machine, and splicing accuracy can be achieved so as to eliminate broken layers and light waves. The 3D stereographs out of fixed printing range of the machine can be printed on a flat straight printer without using a plurality of raster plates for splicing, three-dimensional effect influences caused by image splicing are reduced, and effects in printing of large stereographs are excellent.
Description
technical field [0001] The invention relates to a 3D three-dimensional painting printing method, in particular to a seamless splicing and printing method for a 3D three-dimensional painting grating plate. Background technique [0002] With the rapid development of science and technology, 3D stereoscopic paintings are more and more popular among people, and its application scope is constantly expanding. Only in the advertising industry with huge commercial output value, how to successfully cut 3D products into the advertising market will be the booming 3D industry. eruption point. [0003] Because 3D image products are limited by their materials and production equipment, the production of large-format advertisements has always been the bottleneck of 3D image development. How to break through the bottleneck and create new models is the direction of our unremitting efforts. [0004] There are two production methods for 3D three-dimensional paintings: one is printing. At presen...
