8、stomer- Defined Quality Orientation（为客户定义的质量定位）Key Terms Questions Chapter 1The Printing IndustryIntroductionPrinting has been identified as the single most significant technological development in the human history. Prior（原始的） to the invention of printing all information and communication was trans
9、mitted（传播） verbally（口头的，书面的）. Ideas（观念） survived as long as someone could remember the concept. Little information was retained unchanged for more than tree generations. Folklore（民间传说） and legend（铭文，图例） formed the base for all cultures. It was not easy to communicate messages to a large number of pe
10、ople until the invention of printing. The oral tradition（口头流传的故事） was limited to small groups and the memory of the speaker.Printing created the ability to record ideas（观念） so they could survive across many generations. It also allowed information to be communicated exactly to any number of people.
11、Once ideas and information were made permanent（永久的，永恒的） and everyone had access to them, true science and technological development began.The foundation, and power of print is the ability to reproduce graphic（形象生动的） symbols and messages in large quantities. Graphic messages are possible because line
12、s can be made into shapes that have meanings to human beings.Printing TechnologyAll printing processes reproduce（复制，重现） lines and/or dots（圆点） that form an image. Printing is the process of manufacturing multiple copies of graphic images. Although most people think of printing as putting ink on paper
13、, printing is not limited to any particular materials of inks. The embossing process（击凸压凹） uses no ink at all, and all shapes and sizes of metals, wood（木材）, and plastics are common receivers（承印物）of printed messages.Major Printing ProcessesThe following five major printing processes are used to repro
14、duce graphic images:l Relief printing（凸版印刷）l Intaglio printing（凹版印刷）l Screen printing（丝网印刷）l Lithographic printing（平板印刷）l Electrostatic printing（静电印刷）Each of these processes is suited for specific applications（具体应用）, such as newspaper, book, package, or textile printing.Relief PrintingThe relief pri
15、nting process includes letterpress printing（凸印）, flexographic printing（柔性印刷）, and all other methods of transferring an image from a raised surface (Fig. 1a). Although it was once a major process in the printing industry, letterpress printing has been replaced largely by other printing processes. Mos
16、t relief printing done today is done with flexography. Flexographic printing is used extensively（广大地） in the packaging industry for printing on corrugated（有波纹面的） board, paper cartons, and plastic film（塑料胶片）. Flexography is also becoming a significant process for printing newspapers, newspaper insert
17、s, catalogs, and directories.Intaglio PrintingIntaglio printing is the reverse of（的反面） relief printing. An intaglio image is transferred from a sunken（凹的） surface (Fig. 1b). Copperplate（铜版） etching（蚀刻版画） and engraving（雕刻） are two intaglio processes. Industrial intaglio printing is called gravure（凹印）
18、. Gravure is used for extremely long press runs. Cellophane（玻璃纸） and aluminum-foil（铝箔） candy bar wrappers are two common packaging materials printed with gravure printing. Readers Digest（读者） and National Geographic are two of the many national magazines which printed with gravure.Screen Printing（丝网印
19、刷，Artron）Screen printing transfers an image by allowing ink to pass through openings in a stencil（模板） that has been applied to a screen mesh（筛眼） (Fig. 1c). The screen printing process is sometimes called silk screen printing. Silk is rarely used to hold the stencil industrially, however, because sil
20、k is not as durable（耐用的） as industrial screen materials. Some of the industrial uses for screen printing include printing on plastic such as round plastic containers（塑料容器）, printing large display signs and billboards（广告牌）, and printing on textiles（纺织品印刷）. Another major use for screen printing is in
21、the manufacture of printed circuit boards （电路板）for electrical/electronic equipment.Lithography（平板印刷，Artron）Lithography as it is known today is a relatively new process, dating from around 1798. A lithographic image is transferred from a flat surface (Fig. 1d). Certain areas on the surface are chemic
22、ally treated to accept ink while other areas are left untreated so that they will repel ink. When the surface is inked, the ink remains in the ink-receptive areas, but not in the untreated areas. When a material such as paper contacts the surface, ink is transferred to（转移） the paper. This process is
23、 sometimes called planography.Offset lithographic printing（平版胶印） is the most widely used printing process in the commercial（商业的） printing industry. Its major application is for printing on paper; thus it is ideal for printing newspapers, books, magazines, pamphlets, and all other forms of paper publ
24、ications.Electrostatic Printing（电子印刷）Electrostatic printing was invented in 1937 by Chester Carlson. It involves creating an image by electrostatically charging areas of a special drum（鼓声） (Fig. 1e). As a result, the drum attracts a dry or liquid toner（调色液、调色剂）. The toner is then transferred and fus
25、ed（融合） to a sheet of paper.Even a decade ago, electrostatic printing would not have been classified as one of the major printing processes. However, today electrostatic reproduction has become a standard part of digital printing. When a “copier or printer” can deliver 6000 or more images that meet o
26、r exceed traditional ink density（密度） targets per hour, the “copier or printer” must be recognized as a printing press.Although there are several older printing processes, such as collography（书法）, which prints from a fragile（脆弱的） gelatin（透明的） emulsion（乳胶）, these five major printing processes account
27、for（说明，导致，引起） nearly 99 percent of all work done in the contemporary printing industry.Fig. 1 Five main printing processes(a) Relief printing transfers an image from a raised surface(b) Intaglio printing transfers an image from a sunken surface(c) Screen printing transfers an image through a stencil
28、(d) Lithographic printing transfers an image chemically from a flat surface(e) Electrostatic printing transfers an image electromagneticallyPrinting technology has long been a powerful tool for social change. Edward George Bulwer-Lytton wrote, “The pen is mightier（锋利的） than the sword（文笔比刀剑更锋利）.” But
29、 his statement（声明） assumes that the ideas the pen recorded are distributed. Without printing, few would read the words, and the pen would be a very weak weapon.Printing Cycle（周期）Since the time of Franklin, the basic cycle of the printing industry has not changed much from the following procedures:1.
30、 Identifying a need2. Creating an image design3. Reproducing the image design4. Distributing the printed messageThe printing cycle begins with an identified need. The need might be as simple as the reproduction of a form or as sophisticated as a poster intended to change human attitudes. It could be
31、 as ordinary as a package designed to convince a consumer to buy one designed to convince a consumer to buy one brand of cereal rather than another. Whatever the need, a graphic design evolves. Special design agencies are often set up whose sole purpose is to sell ideas to clients and work closely w
32、ith the printer as the design is turned into print.The function of printing management is to be responsible for creating and controlling the reproduction process. Skilled workers must be employed and an organization created that efficiently and effectively delivers printed products. Once a job is pr
33、oposed, the most efficient printing process must be identified. Such variables as the type pf material to be printed, length of run, number and types of colors, time requirements, desired quality, and customers cost limitations must all be considered. An estimate must be made for each job. A profit
34、must be made, and yet the estimate must be low enough to attract work in a very competitive market. If the customer approves the estimate, management must schedule the job, arrange to obtain all materials, ensure quality control, and keep track of all phases of production so the job is finished on s
35、chedule.Sequence of（连续） Steps in the Printing ProcessesThe printing industry has historically consisted of shops identified with particular processes, such as relief printing or lithography. Craftsmen were trained and then bound by union or guild structure to a particular process. Recently it has be
36、come common for a printing establishment to use a variety of printing processes. Regardless of the printing process used, however, there is a sequence of production steps that all printing follows. This sequence consists of the following steps:l Image designl Image generationl Image conversionl Imag
37、e carrier preparationl Image transferl FinishingThe point of a printed product is to meet a need, such as to inform（通知）, persuade（说服，信服）, entertain（考虑）, or convince（相信，确认）. The design must fulfill（满足） the customers need. In the image design variables（可变化的） such as type style, visual position, type s
38、ize, balance, and harmony（风格，视觉定位，类型，大小，平衡，和谐） are all considered. After the customer approves the design, the image must be generated and made into a final form. Specifications（规格） developed during the image design stage（舞台形象设计协调） are carefully followed during image generation（图像形成）. Traditionally,
39、 image generation was performed by hand, perhaps using photographic techniques. Advances in computer technology, however, have moved most image generation to the computer monitor and keyboard.Traditionally, printing processes relied to a large degree（程度） on photography. Images were converted to（转变）
40、transparent film in the image conversion step and then photographically transferred to an image carrier（载体） during the image carrier preparation step. Computers have revolutionized image generation and forever changed the way that image conversion and assembly（配页） happen. It is now a digital process
41、 happening within software. But no matter how advanced the processes have become, images and pages must still be assembled and prepared for a digital venue like the Internet.The image must be printed onto a receiver material during the image transfer step. Finishing is the last step, which combines
42、the printed material into a final finished form that can be delivered to the customer. This may include cutting, perforating（打孔）, scoring, folding, inserting, stapling, binding（结合）, or packaging.Organization of Printing ServicesThere are several ways to categorize（分类） printing companies. One traditi
43、onal way is by the kinds of services or produces the companies deliver（公司提供）. With this view, printing organizations can be classified into eight distinct areas:l Commercial（商业的）l Trade shops（交易商店）l Special purpose（特殊目的）l Quick printing（打印店）l In-plant（厂内）l Publishing（出版社）l Packaging（包装类）l Related in
44、dustries（相关产业）Commercial PrintingCommercial printing is done by a company that is willing to take on nearly any sort of printing job. Commercial printers can usually handle a large variety of printing jobs, regardless of sheet size, number of ink colors, length of run, or even binding requirements.
45、Typical products produced in a commercial printing shop include small business cards, letterhead stationery, posters, and four-color glossy advertising sheets for mailing. If a commercial printer does not have all of the equipment or skilled staff to perform a whole job, parts of the job, such as di
46、e cutting, foil stamping, or binding, he may be subcontracted to trade shops.Trade ShopsSome companies provide services only to the printing trade. These are called trade shops. Not all commercial, special purpose, in-plant, publishing, or packaging companies can afford to own and operate all the eq
47、uipment necessary to meet their total production requirements. For example, a company might decide not to buy bindery equipment because only a small percentage of its work requires folding, collating, or binding. When the company receives a contract that requires binding, it sends it to a trade shop
48、 that specializes in binding.Special Purpose PrintingSpecial purpose printing is defined（定义） by the limited type of jobs performed by a company. One printer might print only labels. The printer would purchase special equipment and accept orders for only labels. However, the printer would make labels to any size, shape, number of colors, length of run, or purpose. A
