Traditional and digital manuscript essay

although Hong Kong is still in its infancy in adopting digital manuscript, some printing houses have printed works satisfactory to customers only based on digital manuscript, which proves that digital manuscript is not as difficult to master as rumors. This paper tries to start with analyzing the elements of digital manuscript, and summarizes the advantages and limitations of digital manuscript, so that readers can refer to it in application

the relationship between typewriting and printing

from the perspective of production, color printing is a process based on the point color principle, and production requires strict accuracy and stable repeatability. However, there are many factors that affect the printing color, such as the characteristics of paper, ink thickness, printing pressure, air humidity, and the quality of plate making. Some factors will affect each other, and the increase or decrease of each factor will lead to changes in other factors, thus affecting the quality of printing color. Therefore, it is necessary to estimate the comprehensive effect of various factors on the printed parts before production, so as to make adjustments, and proofing is a production simulation before actual printing

generally speaking, typewriting provides the following three functions: first, it is used to check the effect of color separation and plate making, to determine whether the color of the picture is processed correctly, and to provide a basis for revision. Second, it is worth learning from the technical requirements used by Chinese plasticizing enterprises to check the registration and point spread value of film, which can be used as a reference for actual printing. Third, as a communication tool, it will be signed and confirmed by customers before printing, and it will be the standard for future receipt

color quality of ink proofing

due to the importance of proofing in the printing process, printing plants with strict requirements will not only establish data to control production, but also adjust the proofing conditions to be very close to the actual printing situation. For example, the paper used for each typewriting is the same batch of paper used for actual printing. During typewriting, wet printing and wet inking method is adopted, and the printing pressure of typewriting is also adjusted to the pressure used for actual printing. With this arrangement, the printing characteristics and dot expansion of the paper are reflected, and the produced manuscript is of course of great value as a reference in actual printing

however, it takes a certain cost to print such a high-quality manuscript. In addition to investing in additional space for stacking paper, we need to invest in additional equipment to control humidity. There are also technical specifications for the process of typing itself. A particularly important point is the overlapping field density of the manuscript, which is required to be the same every time

monochrome flatting machines are generally used in the drafting service in the market. The ink supply and pressure regulation are decided by the master according to the situation, and the goal is to make the drafting effect pleasing to the eye. However, this practice often sacrifices the stability of the color of the manuscript and takes less account of the requirements of printing, resulting in the same set of films. If you draft twice, you will get two different results, which also makes the actual printing and the color of the manuscript often differ greatly. Disputes often arise between printers and buyers

due to the serious shortcomings of color instability in the manual printing method, foreign printing plants gave up ink printing after the 1980s. A) according to the type of output source, there are mainly Electromechanical, hydraulic, pneumatic, electromagnetic and other types; b) According to the types of instigation at the end of measurement, there are mainly digital display and pointer; c) According to the relationship between the load on the sample and time, there are mainly static machine and fatigue machine, which are replaced by more stable chemical proofing, among which colorart, cromelin, matchprint, etc. are commonly used. However, chemical proofing only produces one sample at a time, and there is no staccato proofing. For masters who are used to monochrome and two-color machines, it undoubtedly increases the difficulties in color matching, so it is not popular. In addition, the materials used are more expensive, and chemical proofing has never been popular in Hong Kong. As a result, printing masters in Hong Kong generally lack experience in dealing with non ink proofing

great breakthrough in process: first look at the manuscript, then print the film

digital manuscript is a matter after the emergence of large-scale electronic composition system. Because the technology of image digitization is becoming more and more mature, manuscript writing also began to develop in the direction of digital. It is also divided into soft type and hard type. The so-called soft typewriting refers to viewing color on the screen. Its main purpose is to facilitate the trimming in the process of color separation. It is generally only used for internal control. However, with the popularity of color management and network technology, some 4A advertisers have used remote soft typing to communicate with customers

hard typewriting is represented by iris2044 inkjet typewriter, which won the printing technology award of GATF that year. Due to the advantages of iris printed samples, such as stable color and very close to the printing effect, many foreign printing buyers are willing to take iris samples as the receiving standard. However, the machine must be operated with Scitex color system, and it is only used by a few printing plants in Hong Kong that print foreign books and periodicals

one of the most important contributions of digital typewriting is to improve communication with customers. Before digital proofing, the film must be output first, and then the proofing. If customers are not satisfied with the color, they have to re print the film before proofing, which often wastes a lot of money and time. With digital proofing, customers can first see the manuscript samples and output the film only when they are satisfied. This can not only save costs but also improve communication. It can even be done while separating colors. It can be described as an important breakthrough in the printing process

color simulation, each method applied

at present, the more common digital typewriting, including inkjet printing technology, thermal sublimation printing technology, and thermal wax pad printing technology, how can these different materials and printing methods achieve the effect of simulated printing? In addition to constantly improving the pigments of printing materials to make them as close as possible to the hue of inks, developers are committed to developing exclusive gamut compression technology in color simulation. The so-called color gamut refers to the full range of colors that a device can express. Theoretically, if the color gamut of digital proofing and printing absolutely coincides, it can completely simulate all the color effects of printing. Although various developers have invested a lot of research in gamut compression, it is a pity that there is still no recognized best scheme at present, especially in the simulation of spot color, the simulation of printing effect in order to make the residual clean resin flow out of different papers, dot structure and printing density, there is still considerable room for development. Therefore, gamut compression is a special test item when choosing digital typewriting

printing technology is the key

it is very important for printing technology and printing stability of printing plants to obtain the expected printing effect according to digital proofing. In foreign countries, some people have done experiments and exported 16 sets of the same film to 16 factories for printing. In Wuzhou, Guangxi, the factory price of scrap steel increased by 20 yuan/ton; Yantai new Oriental metallurgical scrap purchase price increased by 20 yuan/ton; The scrap price of Henan Minyuan special steel increased by 30 yuan/ton; The scrap purchase price of Guangdong Jieyang Daxing steel plant increased by 20 yuan/ton; When the benchmark price of Jincheng Fusheng scrap steel increased by 30 yuan/ton, these factories were asked to produce according to daily standards. Among them, 8 have good technology, and the colors printed are very similar, while the other 8 have weak technology, but the effect is very uneven. Because digital proofing is more stable than manual proofing, if the selected printing factory has insufficient technical strength, it will take more time to make trial printing adjustments each time, so as to be consistent with digital proofing, and additional surcharges may be charged. (don't be surprised, because it's very, very difficult to achieve the stability of a code printer. It's easy to understand the difference between the two in automation and production speed.)

in foreign countries, chemical drafting and digital drafting are currently in parallel. In Hong Kong, ink drafting is also believed to be popular for some time. However, with the popularity of computer direct plate making, the increasingly mature room (riponceoutputmany) output technology, and the continuous decline in the price of typewriters using printing points, digital typewriting will gradually become the mainstream. When using digital typewriting, readers only need to pay attention to the color gamut compression of digital typewriting, and fully discuss with the printing factory in advance. They can absolutely print satisfactory prints based on digital typewriting
