Packaging and Printing Engineering

Commodities into circulation, consumption indispensable conditions. The role of packaging has the following aspects: ① to achieve the value of goods and use value, packaging printing (packagprint to a variety of packaging materials for the main products of printing. Packaging packagecontainer or wrapping, packing, packing, decorating and other operational processes. Packaging is a continuation of the commodity production process in the process of circulation. And is a means of increasing the value of goods; ② protection of goods from the sun, wind, rain, dust and other natural factors, to prevent volatilization, leakage, melting, staining, collision, extrusion, loss and theft and other losses; ③ to the flow of storage, transportation, transfer, marketing, such as loading and unloading, inventory, palletizing, shipping, receiving, transfer, sales counting, etc.; ④ beautify the goods, attract customers. conducive to promotion. Packaging refers to the design and production of containers or wrapping a series of activities. Packaging as a supporting service industry of the national economy, along with the continuous development and growth of China’s socialist construction, especially since the reform and opening up, the socialist market economy system, the packaging industry has been able to develop rapidly, is forming a paper, plastic, metal, glass, printing, machinery as the main components, with certain modern technology and equipment, more complete categories of modern industrial system. China’s packaging industry has used more than 20 years to complete the developed countries nearly 40 years of development journey, basically changed the first-class products, second-rate packaging, third-rate price “situation. Packaging industry has been scattered from a backward industry, the development of a certain modern technology and equipment, classification of a more complete industrial system. The significant feature of the development of today’s packaging industry is the internationalization of the packaging market, the globalization of the development of the packaging industry, the development of the packaging industry in various countries are increasingly interrelated and interdependent degree. Into the mall, almost anyone understands what is packaging. But once engaged in packaging design, but inevitably often by the dazzling brand of goods, a variety of packaging forms coupled with a variety of advice “can not get the main pulse. Although the definition of packaging in various countries are under a clear and concise provisions, such as the United States: packaging is the preparation of products shipped and sold. Britain: packaging is the art, science and technology for the transport and sale of goods made in preparation. Canada believes that packaging is the product from the supplier to the hands of the customer or consumer and can maintain the product in good condition tools. The country has long defined packaging: for the protection of the product in the process of circulation, to facilitate storage and transportation, to promote the sale of aids, etc. The general term. Packaging printing – color blending Packaging printing If the packaging printing and decorative design of the color and then fully conceived, from the three primary colors of yellow, magenta, blue to the three primary colors of red, green, blue, and then four complex colors of purple red, bronze, olive green, black, will be able to combine into a new form of expression, just as people are already familiar with if the different ink color shades (hue) different ink brightness and different ink color Color degree combination of blending together, will also give a soft and harmonious feeling of beauty. Throughout the domestic and foreign packaging printing ink color card selected colors, in addition to the three primary colors, the vast majority of composite colors, compound (combined) color blending itself is a color science, formulated packaging printing color is ultimately used I visually to determine its effect, good, poor and poor. The use of packaging printing decorative colors to the goods I need, decorate a dazzling array of colors, constantly adjust the work, life environment, will give a positive stimulus, conducive to the work, quality of life. The same environment of commodity packaging decoration and the coexistence of several colors, so the coordination between the color is always the subject of endless research. (Such as complementary red and green) color (two colors add up to white) sometimes with bad will give people a sense of tackiness, well blended, will give people a strong and eye-catching feeling. Light yellow with red-brown, will be close to the color between the yellow and red, the tone is similar to give people a harmonious beauty. There are dark green and light green with the color of fresh and eye-catching. The use of the elimination of color and color at the same time with the method, giving a bright feeling, but also to protect the eyes. Red, white, blue three hues at the same time in a package, giving people the feeling of: red hot, white pure, blue solemn, reflecting the beauty of a commodity material. Although China has been developed as early as the 1950s, China’s color chromatography, and more than 4,000 varieties in 56 enterprises are summarized as now unified PTAWZ and other five major types of 86 printing inks, and the successive development of 29 testing standards. In addition to the various packaging printing ink factory printing ink color card in the packaging printing enterprises to promote and distribute, as a packaging printing and printing ink designers and workers should not be limited to the existing ink color card and color range, can often be combined through the use of Menzel color chart Chinese color system physical sample book and electronic computer color matching, to gradually meet the different requirements of the user’s purpose printing printing printing:GraphArts/GraphicCommun the process of using printing plates or other means to transfer graphic information from the original to the substrate. Printing is one of the four major inventions of ancient China. Together with the compass, gunpowder, and paper, it is known as one of the four great inventions of ancient China. The invention of printing, the representative of the wisdom of the ancient working people of China, has made an immeasurable contribution to human civilization, so it is only fitting that some people call printing the “mother of civilization. In a literal sense, printing is the process of making a mark, and rubbing is the process of brushing. When a brush is used to make a mark on another object, it is called printing. In short, printing is an industry that produces printed matter. The production of printed matter is similar to that of seals. First, the seal (plate) is engraved and then the seal (plate) is stained with printing oil, and then the printing oil on the seal (plate) is transferred to paper, silk, leather, and other substrates, which is a printed product. Bark cloth printing picture In terms of the scientific point of view, where the object (narrowly defined only in terms of paper) with traces, and the traces (by a large number of copies) can reflect or absorb the light irradiation, through the human eye, so that the human visual nerve to identify the shape and tone of the traces, said to be printing. From a cultural point of view, printing is a method of expressing and transmitting human thoughts. In ancient China, printing was done by using a brush with ink to coat the printing plate, covering the paper on the page, and then using another dry brush to lightly brush the back of the paper, so that the raised reverse text on the plate would be printed on the paper as a positive text ink mark, because a brush would be a print, so it was called printing. In general, printing is a direct or indirect method, the original image or text for the printing plate, the plate coated with color printing ink, the color printing ink transfer on paper or other substrates by pressure, and rapid mass reproduction of an industrial project. The oracle bone picture now has long been without brush printing, and there is even no need to press, that is, the printing method can be printed copies. Chinese printing has a long history and has spread far and wide. It has been an important part of Chinese culture; it sprouted with the birth of Chinese culture and evolved with its development. If we count from its origin, it has so far undergone four historical periods: the source, ancient, modern and contemporary, a development spanning more than 5,000 years. In the early days, people created early written symbols and sought a medium to record these characters in order to record events and spread experiences and knowledge. Due to the limitations of the means of production at the time, people could only use natural objects to record written symbols. For example, characters were carved and written on natural materials such as rock walls, leaves, animal bones, rocks, and bark. Since the materials for recording writing were very expensive, only important events could be recorded briefly. Most people’s experiences could only be transmitted orally, which seriously affected the development of society and culture. The invention of the seal picture The invention of printing greatly changed this landscape, and people’s accumulated experience could be written down, reproduced and disseminated in large quantities, which is a huge change in the cultural landscape of society, thus allowing more people to have the opportunity to read. With the passage of time and the development process of social and cultural undertakings, the hand-carving techniques that emerged during the Neolithic period in China and were used for the engraving and patting of written symbols and patterns, as well as the bark cloth printing process, gradually developed from rudimentary and rough engraving to complex, refined and standardized engraving. Eleven centuries BC before the Shang and Yin period, has been used for oracle bone characters carved Western Zhou, engraving technology combined with the ancient smelting technology, the emergence and development of the casting or engraved bronze vessels. From the Eastern Zhou to the Qin Dynasty, the style of stone engraving became increasingly popular, making this ancient hand-carving technology progress by leaps and bounds in both quantity and quality, and opening up the precedent of seal stamping. It made an important contribution to the development of Chinese culture. At the same time, it also created opportunities and conditions for the further development and perfection of hand-carving techniques. Since the Qin and Han dynasties, the seal sealing clay, mold printing tiles, belong to the expansion of the field of application of hand carving and the widespread use of transfer reproduction. As for the subsequent emergence of topography and the further development of fabric printing, which is essentially a prototype of printing printing can be divided into four basic categories: a letterpress printing; b intaglio printing; c lithography; d hole plate printing. Letterpress printing is one of the oldest printing methods. When printing using a letterpress plate with a raised surface for printing, ink is applied to the surface of the letterpress die and then embossed onto the paper, and the ink on the surface of the die is transferred to the surface of the paper to form an impression. Hand printing, Leno whole line cast printing, lead plate printing, electroplate printing, and photographic
