The image-forming principle of column mirror grating is lens curve refraction catoptric imaging principle, and there are many lens pillars closely in its front usually, and its back side is the plane.
Common column mirror grating has film material column mirror grating (being the mold pressing grating), film material column mirror grating is by the principle that two main pressure rollers are pressed the film material to be carried out the grating that thermoforming processing forms, belong to post forming, article two, one of main pressure roller is the mould roller that there is strip post mirror former on the surface, another is the elasticity pressure roller that the surface has certain elastic material, adopt the elasticity pressure roller can not operate the mould roller easily, the convenient manufacturing and use, but the elasticity pressure roller can produce surface deformation inevitably in the process of press membrane 3 D grating, thereby influence the film material column mirror grating lenticular shape in surface and smooth finish, flatness, make product thickness inhomogeneous, mouldability, focusing is very poor, the product of producing sometimes in addition pro and con all can not distinguish, therefore can only process some more coarse products, produce low line number, broad-brush grating, the stereogram made from this grating, the pattern fineness is low, and stereoscopic sensation and sharpness are very poor.
The utility model content
The purpose of this utility model is at above-mentioned the deficiencies in the prior art, provides a kind of for stereoeffect and the good grating sheet of sharpness of making three-dimensional postcard.
The technical solution of the utility model is achieved in that a kind of for the grating sheet of making postcard, its upper surface is arranged with some being parallel to each other and continuous lens pillar, the lower surface of grating sheet is the plane, the top of described lens pillar is arc-shaped curved surface, orientation along each lens pillar forms continuous curve, and the grating sheet of per inch is distributed with 89.5～90.5 lens pillars.
The grid stroke number of described grating sheet is 90 lines.
Described arc-shaped curved surface is one section circular arc camber.
The radius of described circular arc camber is 0.1458～0.1877mm.
The thickness range of described grating sheet is 0.45～0.75mm.
Described grating sheet is polypropylene, Polyvinylchloride, poly-to stupid dioctyl phthalate ethyl ester or polymethacrylate.
The utility model be used for to be made the grating sheet of three-dimensional postcard can one-shot forming, transparency height, good moldability, not yielding, sharpness is high, easy post-production; Line number that be used for to make the grating sheet of three-dimensional postcard is set to 90 lines, and making and viewing and admiring distance usually behind the stereogram is 0.3-1 rice, and the increment that is mainly used in postcard or some little shape cards, all kinds of commodity packagings is decorated; Grating sheet of the present utility model cooperates the clear fineness of three-dimensional postcard that makes with corresponding high precision printed patterns.
