Problems solved by technology

[0003] In addition, when the existing grating plate is printed, the printing needs to be aligned with the lens. When the low LPI (Line per Inch) grating plate, that is, when the LPI is less than 150, the above three existing printing methods can still be aligned, but when the LPI is greater than 150 , the alignment of the printing and the lens of the grating plate will be very difficult, and a high-cost control method must be used to successfully align the printing

Abstract

The invention provides a grating plate printing machine. The machine is provided with a printing main wheel, at least one flexible or convex printing base arranged on one side of the printing main wheel and internally provided with an ink groove and a printing device, a T-shaped die head arranged on the upper side of the printing main wheel and a plate wheel arranged on one side of the printing main wheel and adjacent to the printing main wheel; hot plastic can flow out of the T-shaped die head to form a curtain-shaped plastic flow, a grating die with multiple columnar magnifying glasses is arranged on the plate wheel, the plastic flow can flow into the gap between the printing main wheel and the plate wheel and is extruded to form a grating plate, cooling liquid is contained in the plate roller, and the grating plate can be cooled. In addition, the invention provides a grating plate printing method.

Description

technical field [0001] The present invention relates to a lenticular plate printing machine and its method, in particular to a lenticular plate printing machine and its method which are completed in the same process of printing and plate making, which can save cost and facilitate alignment. Background technique [0002] Lenticular sheet printing can produce effects such as 3D stereo, image change, and movement, and lenticular sheet printing is also an existing technology. There are three main technologies, the first is lithography, the second is digital printing, and the third is flexographic or letterpress printing, but these three printings are all made of transparent plastic after extrusion molding and then do the grating (film) , and then printed by the three methods. So the process is composed of two steps: 1. First make the lenticular plate with transparent plastic; and 2. Print. [0003] In addition, when the existing grating plate is printed, the printing needs to ...
