Comparing the application of prepress technology in domestic newspaper printing and commercial printing, the prepress technology application of newspaper printing has the following characteristics: First, in pursuit of technical security, it is overly conservative in technological innovation; second, blind pursuit of technical safety. The configuration and matching of equipment and application software are not scientific and reasonable; the third is that there is still no awareness of the process to standardize the operation, and still stay in the consciousness stage of “heavy hardware and light software”.
There are three main reasons for these characteristics: First, relative to commercial printing, newspaper printing pays more attention to technical security and political security. This is an inherent feature of newspaper printing, which is difficult to change. Second, the technology used in newspaper printing, especially It is software, relatively closed, it is difficult to integrate other advanced technologies; Third, few domestic suppliers are willing to take the initiative to promote the pre-press technology innovation of the newspaper industry, because the process of this promotion will be long and difficult.
To change the pre-press technology of the newspaper industry, the most important thing is to change the sealability of pre-press technology to openness. Once the technical barriers are eliminated and excellent prepress technology is used for newspaper printing, newspaper printing practitioners will emancipate their minds and dispel fear of technical security, so that they can boldly introduce new concepts, models and technologies.
From the perspective of the newspaper industry processes launched by various international manufacturers in China, such as Agfa, Kodak Pauline, Klaus, etc., without exception, the 1-bit after RIP
Tiff is used as the data foundation. So many well-known manufacturers have built the newspaper data flow in the way of RIP. At least one reason is mentioned. After RIP technology has unique advantages in the newspaper industry, it is reflected in the following aspects.
*safety. PDF is safer than PS, 1-bit Tiff is safer than PDF. For newspaper printing, when the layout is confirmed by the editor to enter the plate making process, the modification of the document is no longer needed. The editability of the PDF is useless here, which is a security risk. 1-bit The unchangeable tiff guarantees the absolute security of the file.
*compatibility. There are three major types of layout systems in China, including Founder, Huaguang and Adobe. No RIP process can be compatible with these three types of typesetting systems, and RIP can be easily implemented.
*Multipurpose. On the basis of safety, the same 1-bit tiff file can be used for a variety of purposes, imposition, digital proofing, ink presets, CTF and CTP output, and to ensure consistent results. This is also unmatched by the PDF or PS before RIP.
In the process of the newspaper printing factory, there are three links that are most important, one is imposition, the other is proofing, and the third is printing ink preset. Many processes are not recognized in the newspaper industry, and most of these processes are related to the evolution of commercial prepress processes. They are more suitable for commercial printing, and do not take into account the characteristics of newspaper printing. The high-tech reporting process advocated by Gaoshu focuses on solving several major problems existing in the pre-press printing industry, and adopts a method from easy to difficult and step-by-step. Newspaper users can use part of the process or all of the process, but no matter which way, users can directly see the obvious effect of this process. Moreover, since the high-tech newspaper process adopts the post-RIP technology, all the layout files are converted into a standard RIP post-data format before entering the high-tech newspaper process, effectively avoiding the inconsistency of the layout file format. Invalid work. This post-RIP technology also really supports "one-time RIP, multiple output". As long as the standard data after RIP is formed, this data can be transmitted to the imposition, proofing, and output systems without any problems, and the data is unified to the greatest extent.
Newspaper printing will change the awareness of “heavy hardware and light software”, and digital processes, color management and other technical means will be widely adopted by newspaper printing. At the same time, software for newspaper printing will become more and more professional, rather than simply moving the software for commercial printing to newspaper printing. CTP will be accepted by more newspaper printing, but more newspaper printing companies will improve the application software to achieve the efficiency and stable quality achieved by purchasing CTP.
