Newspaper printing digital color solutions

The newspaper industry practitioners have always had misunderstandings about image processing. They believe that the printing requirements of newspapers are not high. Therefore, they never pay attention to the quality of images, and often use ordinary scanners to scan images. Ordinary flatbed scanners often have the following problems due to technical and cost constraints: the screen colors and the actual output colors are not uniform, color cast, and colors are not bright enough. With such a scanner, the scanned image has poor color reproducibility and the image lacks a sense of depth. Once encountering the manuscripts that require high scanning accuracy for producing magazines and pictures, the newspapers can only go out electronic color separation. In the long run, it not only reduces work efficiency, but also has high cost.

Newspaper production requires high-quality professional scanning

In order to increase the competitiveness in the market, more and more relevant newspapers have united to form a newspaper group. Unlike ordinary newspapers, these newspaper groups publish a large number of magazines and exquisite albums. Business contents are even more. Design to advertising, light boxes, exhibition boards and photo production. Newspapers are evolving from black and white to color, with corresponding improvements in quality requirements, especially in terms of color performance than black and white newspapers have very different requirements. In addition, with the increase in business volume, manuscript sources are becoming more and more diversified. In addition to ordinary prints, photographs and transparencies of different sizes and textures also occupy a large proportion. The increasingly wide range of business leads to a straight-line increase in the number of scanned images. The newspaper industry puts forward higher requirements for prepress input devices. The ethical requirements of the scanner, on the basis of fully satisfying the scanning speed requirement, achieve considerable accuracy, ensuring that the picture is enlarged to the A3 format, and the fiber must be present. In addition, the newspaper industry has also put forward higher requirements for the ease of use of scanners. The professional platform scanner with excellent CCD device, high power lens and innovative technology can produce excellent color reproduction effect. At the same time, it has the inherent simplicity of operation and high scanning efficiency of the platform scanner. Prepress professional platform scanners are reported. The industry publishing industry is gradually emerging and becoming the mainstream. Large-format drum scanners, which were widely used in the output center and platemaking industry, are increasingly being replaced by professional high-end scanners with excellent performance.

Newspaper Printing Color Digital Solutions

The press color digital solution based on the Microtek atixScan 2020 Scanner consists of a computer, RIP, color management software and a large format color inkjet printer. The entire system is accurate, stable, fast, and has low operating costs. After the AtixScan 2020 scans the picture grouping input to the computer, the typesetting file can be directly output by the color printer by the proofing effect. Without the piece, the printing effect of the true frame size can be seen in advance, the layout design effect and the image color effect. At a glance. After the proofing results were confirmed by the sample and then printed out, it not only saved the trouble of repeated filming due to frequent changes, but also drastically saved cost and improved work efficiency.

The advantages of digital proofing

Accurate color reproduction and flawless proofs, ColorQuart with AtixScan 2020's powerful scanning color separation software and its built-in CMS color management system, including a variety of input and output device color profiles, providing output device-oriented color space conversion, Picture colors can be reproduced realistically. With ICC color correction software, AtixScan 2020 can customize standard ICC color files, independent of time and different people's use, ensuring the final consistency and accuracy of the scanned colors.

Large format, high speed, and high accuracy With the ArtixScan 2020 multi-format professional clip and multi-frame batch scanning function, the user can pursue the scanning speed and achieve high-precision quality requirements. If the output is large format, in theory, when the picture ratio is 1:1, the accuracy of the original file should not be lower than 1/4 of the output precision. This formula can be used to calculate the original file (dpi) = amplification factor × output (dpi) / 4, such as 2000 dpi resolution scan image, the output accuracy is set to 720dpi, then the image can be enlarged more than 10 times.

Stability As long as the newspaper prints the ICC color profile of the color digital solution, the system passes through the input and output. Whenever any person scans and prints the same file, the color gamut range of the system print sample is stable and the proof effect comes out. exactly the same.

The low cost printing industry printing color digital solution overall investment cost is only 200,000 yuan, scanner 50,000 yuan, calculation 20,000 yuan, printer 100,000 yuan, digital proofing color management software package 40,000 yuan, while the traditional proofing investment More than 2 million yuan. Newsprint digital proofing costs 10 yuan for proofs, 4 for 40 yuan, and the average cost for traditional proofs is 200 yuan to 300 yuan. Digital proofing costs only 1/7 to 1/5 of the traditional proofing. The efficiency of digital printing is also significantly higher than that of traditional proofing. Digital proofing takes only half an hour. Traditional proofing requires at least half a day. In addition, the digital proofing system has a powerful combination of imposition capabilities, according to the paper size and requirements of arbitrary set the number of imposition and number of pages, as well as page rotation, scaling, mirroring and other processing functions, to avoid possible errors in the manual imposition, Improve work efficiency while effectively avoiding paper waste.

The digital proofing process and its working characteristics fully satisfy all the requirements of the entire production process of the color newspapers and periodicals, and is an indispensable and important tool for improving the publication rate of color newspapers and periodicals. At present, newspapers such as the Global Times, the People's Liberation Army Daily, China Sports News, China Business Daily, and the China Economic Observer have adopted press color digital solutions.
