The 1970s and early 1980s set off a digital boom in the printing industry. The understanding of the word digitization at the time was only thought to be due to the use of computers, so digitization was taken for granted and did not feel like it was today. Fifteen years later, the term digital has ringed the world. In the process of gradually infiltrating all fields of society, we are welcoming social transformation that was simply unimaginable at the time. Recently, the word digitization has taken on a global significance. Not only in the field of science, but also in the humanities, social sciences are also widely used. The reason why this vocabulary is recognized by everyone is that the background is due to the rapid development of communication technology that emerged from the advent of the US information highway concept and the interactive network.
The origin of the word "digital"
The word “digital†we often refer to comes from the Latin word “ Digitus, the fingerâ€. Dictionary explanations are "finger", "use numbers", etc. In addition, the word "simulation" is also translated into "similar" and "similar", but the meaning of the two is different. Just as expressed in the etymology, the so-called number refers to the meaning of “scratch index number†and has a “spectral, digital†complex meaning, but in simulation it refers to “counting on the palmâ€. If it is compared with numbers, it becomes "continuity, spectrum". Digital computers are often translated into counted computers, and analog computers are translated into metered computers. If we use the appliances around us as an example, the former is an abacus and the latter is a slide rule.
The effects brought by digitalization The natural phenomena that we have seen around us are all analog. If you think about the continuous changes of light and sound, such as the water in a small river, the sound of a stream, the sound of the wind, the sound of birds, and the light through branches and leaves, you will understand this. We accept these phenomena using analog sensors such as the eyes or ears, and then use the brain for analog processing before memorizing.
Analog information is transmitted through changes in frequency and amplitude. For example, for recording music, the frequency change is expressed from the bass to the treble with a scale, and the change in amplitude indicates the volume.
In 1876, Bell invented the phone and used analog to talk. When you use the phone to make a long-distance call, the voice will be reduced, there will be many noises, and sometimes you may not be able to hear clearly or you may get it wrong. In the simulation, there are problems with signal attenuation and noise effects.
The number is transmitted after the signal is converted into a pulse number, that is to say that it represents a number of pulses per unit time. This is very important. Strictly speaking, it has nothing to do with the height and shape of the pulse. Therefore, it is difficult to be disturbed by noise, and signal distortion may not be caused due to signal attenuation. The Morse signal is one of the digital communications invented 150 years ago. If you can hear two tones, this has nothing to do with the sound quality. It is understandable by remembering what you mean.
Digitally uses pulses to transmit information. For example, even if the amplitude changes, there will be no problem as long as the number of pulses is maintained. This is a major feature of digitalization.
Recently, I have often heard such languages ​​as "from simulation to data." This is a very broad language and represents the movement of society as a whole. However, what we mean here refers to narrowly defined words.
The reason why digital technology has developed so rapidly has fully benefited from the development of various other related technologies. In particular, the development of semiconductor technology and computer technology has played an important role in promoting, and the role of PCM technology cannot be ignored.
PCM is the abbreviation of Pulse Code Modulation Technology. It was a technique invented by a French man named Reeves in the late 1930s. It converted analog amplitudes into impulses and sent it back as digital signals before returning to simulation. Its characteristic is that Information can be transmitted without being influenced by noise, but since the peripheral technology was not sound at the time, it has not been practically used. It has only been used in practice since the 1960s. The key to this technology is to convert analog signals such as pictures or sounds into "standardized", "quantized", and symbolized" signals, which can be used to deliver vivid images from space.
Digitization and printing
In the past, the use of analog processing technology was unconsciously used in the field of plate printing. When the word “digital†became popular all over the world, the printing industry began to vigorously introduce digital technology.
In the electronics field, the first wave of digital computers was created after the University of Pennsylvania developed the first computer. At present, the field of printing has entered the heyday of the wet version and the dry version, or the original color version and the egg green tablet.
The 1960s was a practical period for computerized typesetting and color scanning. The printing industry has begun to use computer machines frequently, but this does not mean that the digital age has arrived. The computer inputs analog information, and then performs S-D conversion processing in the computer, and then performs D-A conversion on the processed data to simulate output.
In 1987, the United States began to enter the practical stage of DTP (Digital Transmission Protocol). There is no change from the original program except for the computer. Japan has also introduced DTP in the printing industry since 1989. From this point on, designers began to use DTP to process text or images, which greatly improved the efficiency of the printing industry. According to the report of the Japan Printing Industry Federation, the number of digital prints for commercial printing in the United States accounted for 25.3% in 1993, 41.8% in 1994, and the exchange rate accounted for 43.7% in 1993 and 59.5% in 1994. Based on this, it is expected that the rate of commercial printing in 1995 will be 52.7%, and digitization will increase efficiency by 72.4%.
On the other hand, the information highway and multimedia that emerged throughout the world from 1994 to 1995 further promoted the digital revolution in the printing field. At present, the printing industry has recently developed multiple CD-ROMs in order to continuously adapt to the output system. One of the biggest characteristics of data output is that it can diversify its output signal. Conventional analog systems, such as printing of film for printing, are limited to output, and data output can correspond to output forms such as communications, multimedia, and databases. Therefore, if it is not diversified, it will be difficult to achieve the digital effect.
Digital countermeasures
There is no special standard model for the digitization of the printing industry, and it is difficult to determine its scope. The most basic is to fully understand the characteristics of digitalization and its effective use in the work.
One of the most important features of digitalization is that it is not limited by distance. It can share information with a computer anywhere and can process information in real time. The realization of the network has effectively played its role. This is not just the meaning of globalization, but it means that digitalization can also play a role in our side. For example, in the field of pre-press printing presses, digitization has continuously promoted the unification and simplification of the program, which allowed the development of pre-pressing to stamping, and then developed from stamping to post-stamping, thus exerting a great influence on the printing form. This will not only make major changes in the elements of printing technology, but will also gradually change people's awareness and ability. At the same time, with the expansion of the scope of internationalization, the scope of people’s technological exchanges has been continuously expanded.
At present, the digitization of the printing industry is moving forward at an unprecedented speed. Therefore, we need to learn more about computer science. At the same time, we also need comprehensive capabilities and extensive knowledge of "printing."
