The future of European printing industry (Part 2)

digital printing is generally suitable for on-demand printing and short version live printing from the conclusion of digital workflow

digital printing has higher unit cost for variable printing of less than 250 sheets and direct imaging printing of less than 1000 sheets, but its profit and loss is small compared with traditional offset printing. Nevertheless, the value of digital printing does not lie in the cost of production, but in the services provided

the digital printing system has opened up new business opportunities and changed the traditional logistics management. This move has a significant impact on the environment of book publishing because it reduces inventory costs and will never fill the catalog of published books. This is to create the concept of "hypothetical warehouse" and eliminate the necessity of physical warehouse

the early investment in the equipment is very small. It can not go through the traditional printing industry. It is very attractive to the sales agents, bookstores, delivery operators and copy shops and is difficult to purchase


di printing press and digital belong to the end result in theory, but for the long version business, CTP is still used to make printing plates, and the traditional printing press is used to start the business quite a lot

it is quite expensive compared with the previous version, but it has other advantages. On the one hand, the negative production does not rely on manual operation. On the other hand, the pre printing preparation time can be shortened according to the perfect overprint accuracy of the processing center in Shenzhen, China that has post-processing Tyvek

in the CTP market, it is roughly divided into thermal imaging and visible light imaging. Recently, people are also concerned about the mode of UV laser. At present, enterprises considering setting CTP processor in the printing workshop have also emerged

on demand printing

the concept of on demand printing is to achieve continuous variable output. It can be generated according to the development of advanced software driver for digital printer input. Once the data is input into the digital workflow system, it will be directly sent to the digital printing engine for random printing

on demand printing adapts to any form of digital data. It can print information sheets, price lists, daily-use equipment, copy services that can improve quality, and other potential commercial activities with assistance

up to now, its main use field is book publishing, so it eliminates printing any number of copies without knowing the real need. Instead, it observes the response of the market and corresponds to the actual needs. It can adapt to the connected orders and maintain the required number of copies

the situation of overstock in inventory and book return from bookstores has been eliminated. Even though there are many varieties in small batches and the unit cost of using digital printing is high, it can be offset by other savings. In addition, for books that can sell more than 100 copies in the year, a digital catalogue of published books can also be worked out

the same attempt is also effective for on-demand container packaging with thick paper, film and foil as raw materials. The problem can also be solved for containers using on-demand printed labels

in other fields, newspapers and periodicals with information as the main force can open up remote markets by making use of the on-demand production of communication chain and dealing with the time decisive victory. Digital printing is ideal for production in places far away from the data center

although DTP has downloaded the internal publications and annual reports of enterprises, they still benefit from on-demand output

digital workflow

in order to make full use of digital, the cooling system must be opened when the oil temperature exceeds 60 ℃; Technology, to minimize interruptions, this indispensable digital information through the preparation process of the digital workflow

open system refers to the time when data is transferred from one system to another. In order to avoid difficult problems, attention should be paid to it

although various data formats are used, the most effective one is PDF. In order to improve business management, it is estimated that it will be more developed if the operation data is provided in the document

among the numerous printing methods, there is no applicable single workflow. Therefore, the workflow mode of specific format may be introduced. At that time, data will not only meet the needs of printing, but also be applied to other media, especially the applications on the Internet

workflow - create value from the whole project

prediction of new products and technologies

1 File format

digital data is active through the workflow system. The form of operating digital data must be safe and easy to be recognized by other parts of the system. For many years, the operation has been solved by a special system dedicated to specific work. The data from this system cannot be completely transmitted to other systems without errors

the early open forms that are still being used include postscript and tiff/it. PDF is still a popular file format, and the development of enhanced PDF continues. The purpose is to adopt an automatic workflow that can be applied to digital printing and multimedia

file specification not only determines the rapid movement of data among users, but also relates to the amount of space occupied by memory and long-term storage system. Although compression can greatly reduce the file size, it often reduces the quality. We are pursuing the most appropriate conditions for the offset of data transmission speed and quality loss

in order to treat the output of digital data of most users, it is very important to maintain the data independent of the output form. Data is being asked to be marked with version code like SGML. Therefore, the final form has to be set by the final stage of the workflow

due to the dangers of many different standards in the use of various application software, the industry should not rely on a single developer product or a technical committee that does not represent the industry, but should allow all users to accept the standards in the production environment, which is very necessary

2. The development of prepress engineering

digitization has eliminated the traditional barriers that only provide physical components (such as negatives, films, etc.) to the printing industry to engage in division of labor. Assignments are advertising design and layout design, and text typesetting is handled separately from color separation and plate making. The workflow is still a physical process. Operations are transferred from one operation to the next by manual handover

nowadays, users and layout agencies want to produce a complete layout design that meets the needs of the printing industry. It is a unified package that includes processed text and images

data confirmation, color management and high-precision color proofing can maintain the unity of data. The final printing must have a production process that ensures the user's expectations and fitness. For example, proofreading, monitoring screen or proofing device, and color calibration of scanner are indispensable roles in printing engineering

if the waterproof of the digital workflow fails and it is not repaired, the re process involves all the processes from the idea formation to the printing output. A single workflow cannot be expected to correspond to various production processes in many different formats of printing and packaging

when data is transmitted between systems, it is important to check whether all data are correctly received due to the manual work of operators. Not necessarily for printing purposes, data is also prepared for CD or Internet use. (to be continued)
