Three-dimensional grating plate Print With the present three-dimensional features, so viewers can see objects from different viewing angle, can see the changes of objects, to be on the three-dimensional objects, but used three-dimensional grating plate before printing, it must rely on artificial photographs of the object, making the time-consuming, and the results may not meet the demand. This article aims to use a three dimensional effect grating array can show the characteristics of their building for the production of dimensional printing, by computer soft, it will be taken to reduce labor difficulties, to improve results and consistency of finished products, and improve processing efficiency.
I. Introduction Common market at present three-dimensional color pictures printed, generally refers to three-dimensional grating plate printing, the current direction of this three-dimensional imaging technology and more commercial development, combined with printing, creative arts and science and technology refined and is widely used
Package Decoration, commodity Advertisement , Interior and postcards, the use of such technology in Nepal had also produced a three-dimensional stamp. Compared with three-dimensional printing and traditional printing, has the following characteristics:
Design Or scenery shot is made, printed materials and more ink for the coated paper and high temperature, so good gloss, bright color will not fade.
3. Three-dimensional printing are coated with concave and convex cylindrical prism-like grating plate, can see the whole picture looks three-dimensional effect.
4. Aids without wearing a three-dimensional display system, will not arise often does not wear aids salt: but also for people watching.
With the computer To plate CTP Technology appears, using high-precision multi-color printing FM outlets. UV technology continues to mature, many equipment manufacturers introduced a variety of types of UV
Offset . Heidelberg, MAN Roland, KBA, Komori and Ryobi have been introduced such as oak printer has this feature. Printer with direct printing rubber plastic grating material is no longer a problem, three-dimensional printing quality is assured, so grating three-dimensional printing plate developed rapidly. In recent years, the domestic three-dimensional printing has been greatly developed. Start printing plate using grating three-dimensional printing technology to produce more complex products. From
Label , Posters to packaging products, and even the plastic cups are examples of its application. Although the three-dimensional printing plate grating products that are not true three-dimensional visual effect, but the grating three-dimensional printing is not just propaganda or art products. Three-dimensional photograph made with the traditional technique compared to the use flexibility in the economy and so on have shown its unique advantage. For example, raster printing three-dimensional map used in the production, in addition to easy to carry, easy to store the merits, but also get three-dimensional map of the concept of entities as a result, when combined with aerial photos or satellite photo images, but also provide a rich visual landscape conducive to the topography, surface features of the judged.
Traditional leaflets of three-dimensional view or print pictures of people, although you can use the single photo of the principle of making false 3D stereoscopic imaging, but the content object to photographs of subjective distance determined by the production staff, then according to the results of such judgments, Use image processing software to artificial methods described hierarchical, stratified and then use the grating plate to complete pre-press processing software, produced original. The results of this approach, changing the surface features of height difference between the real and artificial layered process is quite time-consuming, but also make the results vary, the lack of product consistency.
Plane or image for a three-dimensional map coordinates, the island has been measured with the system of DTM (DigitalTerrainModel, DTM) sets together, thus providing an added layer of objective basis. The purpose of this is grating array can show the characteristics of three-dimensional effect will be applied to produce three-dimensional map plane, by DTM for assistance, the design of a geographic information system software using a hierarchical approach to reduce the manual check and improve product consistency and objectivity, and improve processing efficiency. As the small number of hierarchical concept as that may arise in three-dimensional model of the phenomenon of discontinuous or indistinct, too layered to be increased production time, this article also different hierarchical way, to compare their results to understand the way for the production of .
