Fig. 3 is the flowage structure schematic diagram realizing holographic discoloration method in the embodiment of the present invention; As shown in Figure 3, first, adopting three-dimensional image acquisition equipment to carry out 3 d image data collection to the source object of holographic discoloration, taking 3-d photographs etc., to obtain the 3 d image data that source object is greater than 700dpi as utilized 3D camera.
Secondly, grating photo analysis machine is utilized to carry out copying (copying of volume hologram) of plane transmission hologram to collecting 3 d image data, so that 3 d image data is copied to view data decomposer, as being provided with the computer etc. of light tools program, recycle as the 3 d image data of above-mentioned source object is carried out importing graphical analysis by the light tools programs such as 3D4U Printing, and according to analyzed result, pattern being decomposed into some interference lines, the 3 d image data by source object is decomposed into the view data of two dimension.
Then, above-mentioned some interference lines are imported analysis of image data device entirely, be provided with on the computer of two dimensional image analysis program as imported, after the interference lines decomposited are analyzed according to interference condition by the routine analyzer of recycling as Coreldraw, Illustrator etc., carry out screening, color-dividing process, and then export film source data and individual-layer data.
Afterwards, by film source data input film film setter, adopt the plate-making screen density being greater than 120 lines/cm to make stereosopic printing half tone, and the stereosopic printing half tone made comprise yellow version (Y), pinkish red color version (M), cyan version (C) and black version (K); Wherein, the processing procedure making stereosopic printing half tone comprises the color-dividing process of the number of scanning lines of more than employing 400 line, adds network process etc.; Because stereo-picture pixel is comparatively fine and smooth, and cylindrical lens raster has the reasons such as amplification, in order to obtain the higher printed matter of quality, needs to adopt compared with fine mesh as the mesh of 450-500 carries out adding network process.
Further, in order to improve the color separation linked network of plate-making, the precision of copy, site requires solidly not emptyly to be not less than 5% as site spreading rate, just scene image can be made to keep the level enriched.
Finally, silk-screen printing device is adopted to complete the making of holographic discoloration product according to stereosopic printing half tone and individual-layer data, in stereosopic printing process, because the view data of source object is through decomposing, be made up of the compact arranged pixel of a rule after analysis, through plate-making, combined column runner plate is also wanted after printing, so when selecting cable angle, except will considering the moire that formed between half tone, be also noted that each screen angle and pixel line, the moire that cylindrieal lens plate line is formed, and the netting twine of transverse direction is the most obvious, and 0 degree and pixel line, post mirror line is orthogonal, disturb definition and the depth perception of image, so, 0 degree of screening should not be selected in stereosopic printing, in addition, in stereosopic printing, the screen angle of C, K version should be consistent, and its color ink field density wants high, wherein, during follow-up different pitch stereosopic printing, need the netting twine combination angle adopting different yellow versions (Y), pinkish red color version (M), cyan version (C), black version (K), to avoid the generation of interference fringe, be specially:
When at 0.6 pitch/cm, during the color separation of 100 lines/cm, the angle of yellow version screening be 75-85 ° as 75 °, 78 °, 81 ° or 85 ° etc., the angle of pinkish red version screening be 32-38 ° as 32 °, 34 °, 36 ° or 38 ° etc., the angle of cyan version screening be 62-68 ° as 62 °, 64 °, 66 ° or 68 ° etc., the angle of black version screening be 62-68 ° as 62 °, 64 °, 66 ° or 68 ° etc.;
When at 0.44 pitch/cm, during the color separation of 58 lines/cm, the angle of yellow version screening be 50-55 ° as 50 °, 52 °, 53 ° or 55 ° etc., the angle of pinkish red version screening be 20-25 ° as 20 °, 21 °, 23 ° or 25 ° etc., the angle of cyan version screening be 65-70 ° as 65 °, 66 °, 68 ° or 70 ° etc., the angle of black version screening be 65-70 ° as 65 °, 67 °, 68 ° or 70 ° etc.;
When at 0.31 pitch/cm, during the color separation of 81 lines/cm, the angle of yellow version screening be 62-68 ° as 62 °, 64 °, 66 ° or 68 ° etc., the angle of pinkish red version screening be 20-25 ° as 20 °, 22 °, 23 ° or 25 ° etc., the angle of cyan version screening be 50-55 ° as 50 °, 51 °, 53 ° or 55 ° etc., the angle of black version screening be 50-55 ° as 50 °, 51 °, 54 ° or 55 ° etc.
Further, because the chromatography precision of stereosopic printing requires very high, generally need to adopt PS version to print, but other the positive-type PS plate except the special positive-type PS plate of UV ink, if not through baking process, its pressrun is all lower; So, when selecting other positive-type PS plates except UV ink is special to make stereosopic printing half tone, need under temperature is 250 DEG C of conditions, carry out the printing down technique of 6-8 minute, to increase its pressrun, and when selecting negative-type PS plate to make stereosopic printing half tone, then high pressrun plate to be selected to make a plate.
Preferably, because of the final many and plastic plate compound of stereoscopic print, and cylindrieal lens plate is mostly with certain gray scale, and stereosopic printing uses is 300 wire-mesh screens of very fine, only need shine when printing down to 8.5 ~ 9 one-tenth points, otherwise easy scumming during printing, so just need strengthen the colo(u)r specification in shadow region, to reach the effect of 9 ~ 9.5 one-tenth points.So stereosopic printing is higher than the colored ink field density of lithographic plate four-color process; As Y is 1 ~ 1.1, M in offset lithography be 1.4 ~ 1.5, C is 1.5 ~ 1.6; And in stereosopic printing, Y is 1.33 ~ 1.35, M be 1.31 ~ 1.33, C is 2.
Further, the finished surface of printing also needs covering to boil face lens light screen, so just can have third dimension; The cylindrical lens raster plate of current use has duroplasts and flexible plastic two kinds, and the former mainly contains polystyrene, and the latter mainly contains polyvinyl chloride.Need before cylindrical lens compound to follow and make a cylindrical lens negative template according to relevant parameter, then boundary layer flanging is shaping; Conventional method mainly contains concora crush laminating method, cylinder laminating method and rear subsides method.
In sum, a kind of system and method realizing holographic discoloration of the present invention, holographic discoloration technology is realized by using silk-screen printing technique, and then realize the optical material adopting lower price, print out and have that fineness is higher, color reprodubility good, color fastness is high, and can the hologram image of the advantage such as anti-light illumination aging, tropical deterioration, not only reduce process costs, also improve the image imaging effect of handicraft product, increase adaptability and the range of application thereof of holographic discoloration product.
Above specific embodiments of the invention are described.It is to be appreciated that the present invention is not limited to above-mentioned particular implementation, the equipment wherein do not described in detail to the greatest extent and structure are construed as to be implemented with the common mode in this area; Those skilled in the art can make various distortion or amendment within the scope of the claims, and this does not affect flesh and blood of the present invention.
