What is the difference between packaging printing and printing?
The printing of various graphic and text information on packaging materials and packaging containers is a major category in printing and important link in the production of packaging products. The substrates include not only common paper, plastic, and metal but also wood, glass, ceramics, and textiles. content of the printing is mostly related to the brand, trademark, decoration pattern, advertisement, and instructions for use of the product. It is required that the printed matter a thick ink color, bright color, rich layers, and strong explanatory and appeal power. Printing technology (printing technique) is one of the four great inventions in ancient, and it has made great contributions to the spread and development of human culture. Today, the colorful commodity packaging, newspapers and magazines, trademarks, and advertisements that we in our daily life, as well as the exquisite calendars, desk calendars, and wall calendars, precise maps, banknotes, and stamps, are all products of printing It has become an important means for people to disseminate graphic and text information in large quantities. Packaging printing (package printing) refers to the general term for printing graphics and texts on packaging materials and packaging containers. The national standard (GB9851.1-90) stipulates it as "printing with various packaging as the main products". It is a printing method with a wide range of involvement, complex technology, and special flavor in the printing industry; it has both the technical process as the general printing method and the special process different from the general printing method. With the rapid development of computer technology and the prosperity of the market economy, has effectively promoted the development of the packaging printing industry. As an important medium for disseminating graphic and text information, packaging decoration printing is an effective method for promoting and goods. The diversification of packaging materials has made the process methods of packaging printing change with each passing day. In terms of printing methods, in addition to traditional intlio printing, relief printing, and flat printing, screen printing, flexographic printing, tube printing, decal printing, self-adhesive printing, tin printing, three printing, and processes such as coating, laminating, embossing, die-cutting, and hot stamping are also widely used. The combination of intag and relief printing, the combination of intaglio and screen printing, and the combination of intaglio and flexographic printing have greatly improved the quality of the printed, such as the combination of intaglio and relief printing, where the intaglio part has rich layers and is bright and clear, and the relief part has thick ink color and bright colors. In terms of printing materials, there are paper and cardboard, plastic film, metal, glass, ceramics, leather, wood, and materials, etc. In terms of ink, in addition to intaglio, relief, and flat printing inks, there are also screen printing, tin printing,, scented, and foaming inks, each with its own characteristics. Packaging printing is a kind of printing, which is divided relative to book printing, and is closely linked and inseparable in printing technology.
The concept of printing
The national standard (GB98511.1-90)ulates that printing is "the process technology of transferring the text and image information on the original manuscript to the printing stock by using printing plates or other methods". The traditional of thinking is that: printing is to make the text original (wordoriginal) or image original (pictureoriginal) into a printing plate (printingplate) by using or indirect methods, and then to apply the adhesive color material on the printing plate, and to transfer the adhesive color material on the printing plate to the surface of the stock (printingstock) under the action of external force, so as to obtain the batch of printed matter. Printing is actually the general name of plate making (plaking, which is to copy the original manuscript into a printing plate), printing (the text and image information on the printing plate is transferred to the surface of the stock), and post-press processing (post-pressfinishing, which is the processing of printed products according to the requirements and use performance, such as processing into or making into boxes, etc.). Printed matter has the function of disseminating and storing information. It is different from the information storage methods of recording, video, film and television. It does not need to rely on any instruments and equipment, but can obtain information through the photosensitivity of the eyes. Therefore, since the invention of, it has always occupied an important position in the dissemination and storage of information. With the development of science and technology, there are more and more means of information storage but printing, as the most basic and simplest means of information storage, will still play a role and will not be completely replaced by other information storage methods. The characteristics printing The greatest feature of printing is that it can reproduce the text and image information on the original manuscript in large quantities and economically on a variety of printing stocks. It be said that it can be printed except for air and water. It can be seen that printed matter is the medium of disseminating scientific and cultural knowledge, the material that the education cause must have, and a means of publicity and packaging of goods. The printing industry and the papermaking, ink, and printing machinery manufacturing industries constitute huge industrial system, which belongs to the category of light industry and has the characteristics of general industry. It is based on the basic disciplines such as mathematics, physics,, electronics, mechanics, machinery, and rheology. For a long time, in the process of development, printing technology has gradually formed a set of printing adaptability printing ink transfer principles, etc. around its own printing content. Printing technology is also an art processing technology, which makes people feel pleasant and can't put it down In summary, printed matter is a comprehensive product of science, technology, and art. Therefore, the practitioners of printing should have a high level of culture, master the necessary printing theory knowledge, and also have skilled printing operation skills. They should constantly improve their artistic accomplishment in the production practice in order to produce exquisite and beautiful printed matter
