2.2 Graphical Graphic Processing The flat design draft of the product packaging completed in the graphic design software is an overall planar graphic. This type of graphic file cannot be directly used for the generation of the subsequent three-dimensional visualization, and further processing and modification is required. .
Photoshop is currently the most widely used graphic graphics processing software for PCs and Macs. Now Photoshop is an important guarantee for high-quality color desktop printing systems, preprinting, multimedia, animation, digital photography and coloring. It will be used here to segment the designed packaging plane graphics. The principle of segmentation is the shape and structure of each structural surface in the product packaging structure design. Each structural surface must be divided into a separate figure and named according to the features of the structural face in order to prevent confusion.
On the other hand, photos or pictures are often used in graphic design. After they are acquired by the computer, they are often not directly used. They must be processed as necessary. In addition, after the basic three-dimensional visualization graphics are basically completed, they often need to be processed to obtain a beautiful rendering. This is again only Photoshop. Software is competent. Therefore, in the multimedia design of product packaging, Photoshop is an indispensable application software.
2.3 Real-time realization of three-dimensional visualization Three-dimensional visualization technology is the use of three-dimensional graphics software in the computer to create a completely virtual three-dimensional space on the computer screen. In this virtual space, designers can directly perform various types of three-dimensional designs in three-dimensional ways, such as interior design and product design. The two-dimensional CAD system can only help designers reduce the workload of manual design and drawing. The three-dimensional visualization technology can not only reflect people's rich creative results, but also can grasp the random chance results generated in the process of shape creation. Designers are particularly valuable, and it can inspire people in the design of creative inspiration. Three-dimensional visualization technology can also be very simple to complete the real-time graphical editing and modification, operation is particularly convenient, can most directly reflect the designer's creative intentions.
The packaging itself is a spatial three-dimensional structure. The use of three-dimensional visualization technology to assist in design is the best choice. There are many three-dimensional software on the market, but the most frequently used is 3D studio. MAX software. The three-dimensional texture material can be made from the divided graphics of the graphic design. After the structural modeling is completed, the texture materials are respectively assigned to the corresponding structural surfaces according to the structural plane, and the product packaging can be obtained after the rendering. 3D visualization of the virtual model. Certainly, after the material is specified, some parameter adjustments are necessary. This is because when the 3D studio MAX software generates the spatial structure plane, the “face†is positively and negatively controlled, and is controlled by the normal direction of the “faceâ€; On the one hand, each structural plane has its own three-dimensional coordinate system. The three-dimensional coordinates of the material must be consistent with the coordinates of the "plane." If you do not make the corresponding parameter adjustment, some texture faces will not see the texture effect when rendering. The 3D studio MAX software has good animation capabilities. If necessary, the product packaging design scene can be animated to dynamically display its three-dimensional effect. The general steps of 3D visualization of digital design of product packaging are: firstly use 3D stu-dio MAX software to design and model the packaging structure; and the 3D studio MAX texture material is used to divide the graphic image of the graphic design of the partitioned graphic image. Make; Use the minor object texture edit command to assign the texture materials of each structural surface to the corresponding structural surface respectively, and adjust the parameters to make the visualization effect consistent with its design concept; adjust the output perspective of the effect map and render the output. Finally, design and evaluate the effect of the output. If it is not satisfied, return to the modification.
3 Packaging prepress publishing technology Prepress printing system is a new field developed under the promotion of computer technology. Its production is inseparable from people's pursuit of high-end packaging. The development of packaging and printing requires a pre-press packaging system, but due to some special needs of the packaging, such as hot stamping, embossing and other processes, the thickness of the paper, the requirements of the puzzle and die-cutting plate making, a large number of technical standards and specifications of the box products and other requirements The general prepress system is far from meeting the needs, which requires the development of a prepress system for special requirements for packaging and printing. Peking University is launching a world-class packaging prepress system. This is China's first self-developed professional packaging design system based on the Chinese platform. The system integrates the carton structure design, decoration design and color printing into one, and its function is perfect. If the system is based on the structural characteristics of the packaging carton, it provides a flexible and convenient box-shaped design tool, and the most complete box-shaped database for the collection box type in China, which can be used to complete the packaging carton more conveniently, with high quality and with high precision. The structure design and drawing; The software has a good openness, can output a common data format, can be combined with a variety of graphic images on different application platforms, flexible and convenient processing of high-quality text, graphics and images in the packaging layout Information; interactively imposition on the entire screen on the computer screen, without having to carry out cumbersome continuous operation; in the production stage, the software can output the die-cut data of the packaging carton, such as die-cut data output in the form of processing code, can Direct control of laser processing equipment open mold. The system enables the pre-press graphic design and production to be linked with the post-press processing links organically through a computer, which comprehensively improves the production efficiency of packaging production and the accuracy of manual control of packaging production quality. In short, the Founder packaging system has been able to accurately control all aspects of packaging design, production and processing with all-digital means, and has made China's packaging CAD technology a welcome step toward integration.
In the multimedia age, packaging and printing are an important part of the multimedia world. With the development of modern science and technology, the design of outer packaging of goods has become an important factor in determining whether a commodity can win customers and markets. Digital process flow has become the basis for the development of the packaging and printing industry, resulting in a new digital production system.
4 Conclusion In the developed countries of the Internet, the transformation of packaging design to digitalization has been completed. The design ideas of packaging products also go to the computer platform, including the desktop system, page synthesis, etc. can be completed on the computer, scanning by digital scanners, digital cameras or digital cameras instead. The use of high-tech information technology by the packaging industry to improve its own production capabilities and production efficiency is a concrete manifestation of the development and application of the digital era.
In this era of rapid technological development and increasingly fierce market competition, how can package design adapt to the development of the times, achieve design goals quickly, accurately, and economically; how to find a reasonable, effective, and efficient method and technology to meet the development of the times? The development of packaging itself has become particularly important. Futurists have predicted that the 21st century is a century of digital, network, and multimedia.
