Gao Shu applied to the printing process of newspapers

Comparing the application of prepress technology in domestic newspaper printing and commercial printing, the application of prepress technology in newspaper printing has the following features: First, in order to pursue technical safety, it is overly conservative in technological innovation; second, blindly pursues technical safety. , resulting in equipment and application software configuration and matching is not scientific enough, reasonable; third is still not using the process to regulate the operational awareness, still stuck in the "hardware, light software" awareness stage.

There are three main reasons for forming these characteristics: First, relative to commercial printing, newspaper printing pays more attention to technical safety and political security. This is an inherent characteristic of newspaper printing, which is difficult to change; second, the technology used in newspaper printing, especially It is software that is relatively closed and it is difficult to integrate other advanced technologies. Third, few suppliers in China are willing to take the initiative to promote prepress technical innovation in newspapers, because this process of promotion will be long and difficult.

To change the prepress technology of newspapers, the most important thing is to change the prepress technology's closedness to be open. Once the barriers to technological conservation are eliminated and excellent prepress technology is used for newspaper printing, newspaper printing practitioners will emancipate the mind and dispel the fear of technological security, so that bold new concepts, models, and technologies can be introduced.

From the point of view of various international companies in the press process launched in China, such as Agfa, Kodak Polystar, Klaus, etc., without exception, the 1-bit tiff after RIP as the data base, so many well-known manufacturers All of these methods are based on post-RIP data flow construction, at least to explain one reason. After RIP technology has a unique advantage in the newspaper industry, reflected in the following aspects.

*safety. PDF is safer than PS, and 1-bit tiff is more secure than PDF. For newspaper printing, when the layout has been edited and entered into the plate making process, the modification of the file is no longer necessary. The editability of the PDF is useless here, but it is a security risk. Uncorrectable 1-bit tiff can guarantee the absolute security of the file.

*compatibility. In the domestic newspaper industry, Founder, Huaguang, and Adobe have three major typesetting systems. There is no single RIP process that can be compatible with these three kinds of typesetting systems at the same time, but the RIP can be easily implemented.

* Multipurpose. On the basis of guaranteeing security, the same 1-bit tiff file can be used for multiple purposes, imposition, digital proofing, ink preset, CTF and CTP output, and ensure the consistency of the results. This is also unmatched by the PDF or PS before RIP.

In the printing process of a newspaper company, there are three links that are the most important. One is the imposition, the second is the proofing, and the third is the printing machine ink preset. Many processes can not be recognized in the newspaper industry, and these processes are mostly related to the process of commercial prepress printing. They are more suitable for commercial printing and do not take into account the characteristics of newspaper printing. The high-skills prosecution process advocated by Gao Shu has focused on resolving some of the major problems existing in the press before printing, and has adopted an easy-to-difficult, step-by-step approach. A newspaper user can use part of the process or all of the process. However, regardless of the method, the user can directly see the obvious effect of the process. Moreover, because the high-tech newspaper process adopts post-RIP technology, all layout files will be converted into a standard RIP data format before entering the high-tech newspaper industry process, effectively avoiding the inconsistent format file format. Invalid work. This post-RIP technology also truly supports "one RIP, multiple output." As long as the standard data after RIP is formed, this data can be passed to systems such as imposition, proofing, and output without hindrance, and the data can be unified to the greatest extent.

Press printing will change the awareness of "heavy hardware and light software", and digital technology and color management will be widely used in newspaper printing. At the same time, the software for newspaper printing will become more and more professional, instead of simply moving the software used for commercial printing to newspaper printing to apply it. CTP will be accepted by more newspaper printing, but more newspaper printing companies will improve the application software to achieve the effect of improving the efficiency and quality of CTP procurement.
