It can be used. Generally speaking, a single color is used, ranging from 5-100 black. However, pure black also has disadvantages, that is, the color is not rich enough and easy to copy. It depends on the situation in four-color printing. Text, frame lines, and dotted lines generally use solid black, while packaging, shading, trademarks, etc. sometimes use standard colors. In this case, CMYK four colors can be used, which can achieve special color effects and are not easy to imitate, but using If it is not good, it is easy to have a slight color cast.
In actual application, it still depends on the situation. The original color of the sample must be followed when reproducing. The design can be arbitrarily chosen and the colors are appropriate. If it is a printing or typesetting department, then do not change the original manuscript casually, which involves the contract. This is the reason why most printers are unwilling to revise manuscripts due to quality liability issues.

Printing
Printing (Graphic Arts, also used to use Graphic Communications, that is, graphic communication) is the combination of text, pictures, photos, anti-counterfeiting It is a technology that allows the original manuscript to be transferred to the surface of paper, fabrics, plastics, leather and other materials through processes such as plate making, ink application, and pressurization, thereby replicating the contents of the original manuscript in batches. Printing is the process of transferring the approved printing plate to the substrate through printing machinery and special ink.
Definition
In the national standard GB9851.1-1990 "Printing Technical Terms", the definition of printing is: "Printing is the use of printing plates or other methods to transfer images and text on the original manuscript. The process technology of transferring information to the substrate."
To this end, the latest national standard GB/T9851.1-2008 defines printing as: "The use of analog or digital image carriers to develop colorants. /The copying process of transferring color materials (such as ink) to the substrate"
A few keywords
1. Mass copying: It has been previously defined that a large amount of copying is required to distinguish. Photography and printing. With the emergence of digital printing, printing can be printed on a single sheet in a wide range.
2. Printing plate: In the past, printing was distinguished by the need for a printing plate, but digital printing no longer uses printing plates.
Meaning
In the literal sense, making traces is called sealing, and wiping is called brushing. Rubbing with a brush to leave traces on other objects is called printing. In short, printing is the industry that produces printed matter. The production of printed matter is similar to that of seals. The seal (version) is first carved, then the seal (version) is dipped in ink, and then the ink on the seal (ink) is transferred to paper, silk, leather and other printing substrates to create a printed matter. Computer-printed documents can be produced by laser printers, inkjet printers, or other computer printers. In recent years, computer printing and industrial printing processes have merged, leading to the development of digital printing.
Broad definition of printing
Printing in a broad sense includes pre-press, printing, post-press and various processes and techniques related to image and text reproduction.
The current situation of the printing industry
The current situation of China's printing industry
According to data released by the State Administration of Press and Publication, in 2014, there were 105,000 printing companies in the country , employing 3.394 million people, achieving a total printing output value of 1.08575 billion yuan, total industry assets of 1.17630 billion yuan, total profits of 71.42 billion yuan, and printing foreign processing trade volume of 86.62 billion yuan.
The current situation of the global printing market
The "China Printing Industry Market Prospects and Investment Strategic Planning Analysis Report" shows that the global printing market is divided into three major parts: the United States, Europe and Asia each account for the world One-third of the printing market. The total output value of China's printing industry has jumped to the third place in the world in 2006.
The total value of the global printing market is US$610 billion, with North America accounting for 32%, Europe accounting for 32%, Asia accounting for 28%, and other regions accounting for 8%. However, by 2011, the global printing market will "move eastward": North America will account for 28, Europe will account for 31, Asia will account for 30, and other regions will account for 11. The total output value of the global printing market will reach 720 billion US dollars.
There are two opposite trends in the European printing market: the growth rate of the Eastern European printing market in the next five years is as high as 51, while that of Western Europe is only 12.
Judging from the chart of the world's top 12 printing markets from 2006 to 2011, China has replaced Germany and the United Kingdom to become the third largest printing market. However, by 2011, India will jump from 12th to 8th place. Another significant growth market is Indonesia, with total printing volume expected to reach US$10 billion in 2011.
Printing Industry Trends
China's traditional printing industry has developed rapidly but is deformed. Problems such as low profits, serious information asymmetry, poor communication between buyers and sellers, and acquaintance transactions are common. E-books suppress book and periodical printing, the trend of clean government suppresses packaging printing, and digital printing seizes personalized printing. Our traditional printing industry has overcapacity. The average operating hours nationwide are only 50, and there is a huge difference between the north and the south. It is foreseeable that the Internetization of the printing industry and even the Internetization of the manufacturing industry will be a trend! Online channels are more convenient, more convenient, save resources, protect the environment, and save manpower. For this, the traditional printing industry also needs to change as soon as possible.
