[specific embodiment]
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 2 schematically shows according to embodiment of the present utility model, has the cross section structure of the printed matter of stereoscopic visual effect.As seen from the figure, the printed matter with stereoscopic visual effect of the present utility model has four-layer structure: base material and be printed on the picture and text site layer on the base material, transparent basement membrane and grating site layer successively.Base material can use any printing carrier in theory, and printed matter of the present utility model has applicability widely, can use plain paper as the base material of carrying printed patterns.
Picture and text site layer is corresponding to the printing figure message in Fig. 1 schematic diagram, and printing figure message comprises a plurality of picture and text cellular zones through particular design, and each picture and text cellular zone constitutes by linearly aligned picture and text site.
Transparent basement membrane is corresponding to the blank between printing figure message and the parallax barrier in Fig. 1 schematic diagram.Transparent basement membrane is the transparent membrane of uniform thickness, and it can adopt PET, OPP glued membrane or PVC, PE film to make.In theory, basement membrane is more thick, and the depth of field of stereoeffect is more dark, and visual effect can be more good.But take all factors into consideration the factor such as practicality, technology of printed matter, the thickness of transparent basement membrane is usually more than or equal to 30um, and the gross thickness of base material and basement membrane, and namely the gross thickness of printed matter can be smaller or equal to 0.8mm.
Grating site layer is corresponding to the parallax barrier in Fig. 1 schematic diagram.Different with traditional lenticular lenses, grating of the present utility model site layer is by wrong transparent site and the opaque site of arranging of pressroom on transparent basement membrane, and that simulates grating lattice on the lenticular lenses sees through point and shield point.Therefore, can think that grating of the present utility model site layer is the virtual grating that one deck can produce parallax barrier.Grating site floor also comprises a plurality of raster units district corresponding with the picture and text cellular zone of picture and text site floor, grating site linear array, and form an angle with the orientation of the picture and text site of corresponding picture and text cellular zone, can produce Moire effect thereby make between the grating site in corresponding unit district and the picture and text site.
Moire effect is a kind of optical phenomena that 18th century France researcher More at first finds.From technical standpoint, Moire fringe is the visual results that interferes with constant angles and frequency between two lines or two objects, when human eye can't be differentiated these two lines or two objects, can only see the decorative pattern of interference, this optical phenomena is exactly Moire effect.Fig. 3 shows the principle of grating Moire effect: two close transmission gratings (key light grid and indication grating) of parameter superpose with low-angle, produce the grating that amplifies, and therefore also are referred to as More's enlarge-effect.The site direction of key light grid has determined the direction of Moire fringe, and the enlargement ratio of Moire fringe only depends on two angles between the grating, and angle is more big, and enlargement ratio is more low; Angle is more little, and enlargement ratio is more high.
The inventor is applied to printed matter of the present utility model with grating More enlarge-effect, and the picture and text site layer in the utility model printed matter is equivalent to virtual key light grid, and grating site layer is equivalent to virtual indication grating.Arrange angle by the site of designing different picture and text cellular zones and corresponding raster unit district, make the More who produces in various degree between the different cellular zones amplify striped, thereby can be implemented on the planographic product stereoscopic visual effect in various degree.
Be to reduce technical difficulty, can the picture and text site during design and the grating site between width be set to same parameter, namely be equivalent to two virtual gratings that constant is identical.When two virtual grating constants are identical, when namely width was W between the grating fringe lines, the pass between the angle θ between the Moire fringe lines between width L and the two-layer site was L=W/sin (θ/2).Picture and text site layer adopts common 3D principle design, and grating site layer then adopts the design of grating print principle.
Particularly, the direction that can regulate Moire fringe by the linear array direction of design picture and text site, linear array direction by design grating site, regulate the angle between itself and the picture and text site linear array direction, and then the multiplication factor of regulating Moire fringe, to realize the difference of distant view and close shot.That is, the picture and text that enlargement ratio is bigger are rendered as close shot at stereoscopic visual effect, and the angle between the linearly aligned site is less separately in picture and text cellular zone and the corresponding raster unit district; The picture and text that enlargement ratio is less are rendered as distant view in stereoscopic vision, and the angle between the linearly aligned site is relatively large separately in picture and text cellular zone and the corresponding raster unit district.
The schematically illustrated basis of Fig. 4 the utlity model has the structure of the printed matter of stereoscopic visual effect.As seen from the figure, printed matter structurally is followed successively by base material from the bottom to top, is printed on picture and text site layer, transparent basement membrane on the base material, is printed on transparent epilamellar grating site layer.The grating site in grating site district be between the wrong opaque site of linear transparent network Points And lines of arranging, to form parallax barrier.
The picture and text cellular zone of picture and text site floor all has corresponding raster unit district at grating site floor, and the size shape of cellular zone is unrestricted, can be any size, Any shape according to the needs of picture and text.Between the picture and text site orientation of corresponding cellular zone and the orientation of grating site an angle theta is arranged.Thereby, make between the picture and text net in corresponding unit district and the grating site and produce Moire effect, and then realize stronger stereoscopic visual effect.
Can effectively produce the grating angle of Moire effect usually between 3 to 15 degree.Therefore, printed matter of the present utility model can design direction and the angle of linear array site as required in this scope when design picture and text site and grating site.
In addition, the shape of picture and text site and grating site, size also can exert an influence to stereoscopic visual effect.For example, in the printed matter of the present utility model, dot shape preferably adopts spherical or cylindrical, or other etc. multiple shape.This wherein, the printed matter of being made by spherical or columniform site has identical stereoscopic visual effect in each direction, cube cylindricality site may cause when some direction is observed thereby avoided adopting, the shortcoming that stereoscopic visual effect is relatively poor.The size of site, or the site precision in the printing can be in the scope of 1200-2400dpi.The site precision is more big, and the fineness of picture and text is more high, and it is more fine and smooth that stereoscopic visual effect can seem.Yet in actual applications, also need to take all factors into consideration multiple factors such as printed matter area size, typography fineness, to select suitable print dot density.
In the printed matter of the present utility model, the picture and text site can use black and white or colored ink to print; Black and white or colored ink printing also can be used in the transparent and opaque site of grating site, to realize diversified stereoscopic visual effect.
Printed matter with stereoscopic visual effect of the present utility model can adopt at present ripe printing or offset printing to print, and only needs to be printed on successively on the base material and can to finish through the picture and text site of particular design layer, transparent basement membrane with through particular design grating site layer.The existing stereosopic printing technology based on lenticular lenses of comparing need not grate sticking, and printing technology is simple.Preferably can relatively strictly control temperature and humidity in this printing process, keep stationary temperature and humidity can reduce the paper distortion amount, the temperature that for example can control in the printing process is constant in 50-55 degree scope at 20-25 ℃, humidity.
Stereoscopic visual effect of the present utility model utilizes the Moire fringe principle to realize, when two virtual gratings are stacked together, if horizontal displacement can not influence stereoeffect; If angle displacement can have certain influence to the multiplication factor of Moire fringe.Because the precision of the ripe printing machine that uses is enough high at present, above-mentioned factor is very little to stereoscopic visual effect influence of the present utility model.The existing stereosopic printing technology based on lenticular lenses of comparing does not need complicated accurate technique of alignment, has further simplified typography.In the printing process, the preferred higher printing ink of using character prints, and for example the granularity of printing ink can influence the overlay film effect to avoid coarse ink particle and the particle that dusts in the scope of 0.015-0.04um.
Owing in the printed matter of the present utility model, be covered with transparent basement membrane on the picture and text layer, and need not supplementary protection layer again.Not only simplify production technology, also further reduced cost.Be conducive to produce in batches and extensive use.
The printed matter that the utlity model has stereoscopic visual effect utilizes parallax barrier technology and More's enlarge-effect to produce stereoscopic visual effect, the visual effect excellence; The use printing operation is made, and does not contain lenticular lenses, and pliability is good, has widened the range of application of stereosopic printing greatly.For example, can be used for packaging field, particularly, need not special process and can easily carry out cross cutting, sticking box, packing to printed matter of the present utility model, operation is convenient.In addition, printed matter of the present utility model can also be used for multiple fields such as displaying, decoration.
