In the increasingly fierce market competition, the packaging of goods is particularly important. Good packaging not only give consumers direct visual enjoyment, but also to businesses in similar products in a favorable competitive position. Therefore, the use of advanced packaging and decoration printing technology will be a multiplier effect. Lenticular printing as a special printing method, not only in packaging appearance gives a more rich visual effects, but also to achieve anti-counterfeiting packaging of goods. Lenticular printing anti-counterfeiting packaging can be applied to alcohol and tobacco packaging, food packaging boxes, medicine packing boxes, cosmetic boxes, packing boxes clothing, daily necessities packing boxes, bags and other products. It not only improves the product's worth and popularity, but also for companies dominate the majority of the consumer market has played a role.

The characteristics of 3d lenticular printing

3d lenticular printing is a special printing method, it is through the cylindrical lens lenticular sheet plate specially treated flat image showing a lenticular feeling, sense of depth to produce an image, so that the viewer produce immersive feel. Lenticular printing can reproduce lifelike 3d lenticular objects, the image is clear, rich layers. The original 3d lenticular printing is typically used for 3d lenticular photo or plane compositing, substrates generally choose lenticular sheet or high-quality coated paper and high temperature ink, so good gloss, bright colors will not fade. 3d lenticular printing using the parallax is human, human binocular stereo vision is due to the observation binocular parallax generated when an object, through the brain to produce the feeling after treatment. The left and right eye with a certain distance to view the same object, right and left eyes presented when viewing an object angle and distance are different, the right and left eye image on the viewing angle or projection angle there is a difference, all of the information through the brain processing after generating a lenticular sense of the spatial distribution of the object.

Cylindrical lens lenticular sheet has points like effects when combined with photographic film can be used for 3d lenticular picture of the shooting, when combined with the lenticular pictures can be used to observe the lenticular images. Is a cylindrical lens lenticular sheet formed by a number of parallel cylindrical lens lenticular sheet, the focal length of each small cylinder and thickness of the lenticular sheet is designed to the same distance. The resulting anaglyph stereo-photography lenticular sheet placed back plate, or a combination of software processing after image arrangement of dislocations on the lens focal plane position corresponding to the optical axis. When the eye passed through the column at an appropriate distance from the panel, when viewed left pixel left eye, right eye right pixel, the left eye and the right eye falls stimulation is two images of the same object, parallax, different viewing angles can be seen images at different depths, resulting in 3d lenticular.

The main 3d lenticular printing technology

Lenticular printing has two types: one is the traditional 3d lenticular printing that is, first printing lenticular images, and then with lenticular sheet composite; other is directly printed on the back of the lenticular sheet.
Traditional 3d lenticular printing process to obtain the document, there are two: 3d lenticular shooting and software design synthesis. Anaglyph lenticular shooting to get as a printed document, through photography and 3d lenticular photos can be synthesized simultaneously method, you can also use multi-camera stereo camera or with a single lens camera coupled with positioning guide plane shooting scene around a group of plane images, the film re- After post-optical projection synthesis method. Software synthesizer manuscript is now mainstream way, the use of specialized technology and software, will decompose multiple planar images, compressed into stripes to the left and right in order to view images from different stripes alternating permutations and combinations, and each combination corresponds The width of each lens,3d lenticular image production software can be arranged during automatic processing.

Traditionally one of the key lies in 3d lenticular printing plate. From the printed version of the form to be considered, with the collotype printing out the best, because it does not interfere with outlets. However, due to the limited printing, offset printing is generally used at present, and its methods and flat plate printed version of the color separation process is basically the same. Since 3d lenticular image pixel delicate and lenticular plate amplification, to emphasize the use of fine mesh screens. Plate network lines generally require 120lpi more, such as the network can 300lpi screen for screening positive image made from photographic color separations, print better. But doing so will bring overprint printing difficulties.

The quality of printing 3d lenticular, 3d lenticular picture of the visual effects have a significant impact. Lenticular printing methods chosen not to comply with the loss due to 3d lenticular printing, overlay accuracy is good, should be a lot of printing requirements. 3d lenticular printing technology and general printing roughly the same, but because of the focus and hinder the lenticular sheet, requiring clear lines, overlay accuracy, chromatic error requires less than 0.02mm, otherwise it will affect the image clarity and 3d lenticular.
Lenticular sheet with printed stickers synthetic type, is a crucial final 3d lenticular printing process, requiring raster lines and raster lines to be printed on the precise alignment in order to show lenticular effect. Composite cylindrical lens parameters is required before making a cylindrical lens under overcast template, and then laminated side edge molding. The convex portion of the mold required lenticular sheet, lenticular sheet plate that is a recessed portion to be sharp, and the concave portion of the mold should be close to spherical, smooth. lenticular sheet plate bonding methods are flat pressed against legitimate, lawful drum stick, after the paste method. Level pressure bonding method in which a cylindrical lens shade made film with good reproducibility, reproduce high quality, mainly for medium and small batch production; drum fit cylindrical lens molding method to produce high efficiency, suitable for mass production However, compared with the flat pressed against legitimate, somewhat less negative film reproducibility; Then paste method generally used for large, thick cylindrical lens occasions, but the cost is higher, the pressure required to produce a large 3d lenticular prints.

Raster direct printing is relatively advanced 3d lenticular printing process, different from the conventional lenticular printing process that print this step, the back of the lenticular sheet direct printing direct printing methods, it is necessary to use a special alignment system, the printing plate bars and the lenticular sheet strips of the sheet corresponds precisely, which requires a high overlay accuracy press and the side regulation control precision, the thickness of the printing press should be larger. The use of UV ink printing, you need to consider the UV curing assembly. Also on the print finishing process includes die-cutting, laminating or back-coating processing. Back coating process is back after printing lenticular sheet coated with transparent paint or white paint, can improve the brightness of the image, the image is more clear, structured, can effectively prevent the ink fade or fall off.

Extension of 3d lenticular printing

3d lenticular printing is a common 3d lenticular painting becomes an extension of print, as long as the viewing angle changes can produce dynamic changes in painting effect. Lenticular Mural products from a group of related entities original lenticular recording or synthetic. The combination of several pieces of dislocations image corresponds to the width of each of the lenses were printed in sequence on the focal plane of the lenticular sheet lens. Head-lenticular printing products, two see the same image. To carry out the screen flips, people must have a point of view or the screen from moving when the eyes and lenticular sheet angle changes, we will see one by one continuous image, which saw an animation or change the effect of drawing . When the lenticular sheet line is vertical, it is usually through human viewpoint to produce variable displacement painting effects (called horizontal displacement painting); when the lenticular sheet line is horizontal, the general picture is moved up and down to achieve Mural effect (called the vertical displacement painting). Lenticular sheet  Mural print production methods with the ordinary lenticular printing method is basically the same, but in the process of making the original image material Plains colors, brightness, contrast, saturation and other factors will affect the output change after viewing the painting.

3d lenticular printing technology requirements

Lenticular printing than normal printing requirements more stringent requirements on the accuracy is higher. Required on the manuscript collection of high precision camera, and clearly and accurately record screen; in plate making, requires a high dichroic linked network, copy accuracy, and ensure the scene image remains rich level; lenticular sheet spacing and angle with high precision composite molding requires accurate positioning. Printing paper requires a close, smooth, flat, scalability characteristics of small, usually using coated paper or paper jams. Lenticular sheet film materials are hard plastic and soft plastic lenticular sheet. Hard plastic lenticular sheet stability, high image quality, is not easily deformed, not easily yellow color, and its yield is also higher. Soft plastic lenticular sheet because it contains PVC adverse environmental, and its accuracy and stability is not enough, therefore less used. Solid ink printing ink is not foamed, foaming any visible extent will affect the clarity and lenticular  effect. 3d lenticular printing inks, plastics and standard inks with good flexibility, like, 3d lenticular printed image vivid, levels and sharp edges, smooth-walled ink. Adhesive role is to make print and grating film can be firmly stuck together, and be able to protect the ink layer at high temperatures without discoloration.

Lenticular printing status and future

Lenticular printing packaging decoration currently widely used, such as higher food or cosmetics packaging box, container cover, and many other aspects. Lenticular printing can not only beautify the product, its security is also very good. Lenticular printing anti-counterfeiting trademarks are made by optical refraction data encryption, the same can not like ordinary printed on a replica of electronic color scanner. Optical integrated security encryption methods changed in the past a single, ineffective anti-counterfeiting technology status.  Lenticular printing in tobacco, beverages, cosmetics, clothing, medicines and other anti-counterfeit labels on product packaging play an important role, the experts predict that within a few years will inevitably become a major lenticular trademark counterfeiting methods, the market prospects are very broad. However, due to 3d lenticular printing technology involved complicated, so the development of 3d lenticular printing by technical limitations, but also our country is in the early stages. However,3d lenticular printing simplistic image processing and advanced lenticular and 3D image synthesis software applications, CTP platesetters and the deepening of the FM network, lenticular sheet direct printing process simplification, laser holographic lenticular printing technology research, these new technology development, so we have reason to believe that 3d lenticular printing will be more and more attention, and its own development is bound to enter a new era.
