Postscript is designed to be printed and published as a de facto industry standard for digital prepress technology: Multimedia applications have been developed to a very high degree when designing PDF documents, so it is suitable for print publishing and electronic publishing: after the emergence of web publishing , PDF still found its place. The PDF has features that meet the requirements of cross-media publishing because it is rooted in Postscript technology, inheriting all the advantages of the technology, and taking into account the needs and technical characteristics of electronic publishing. In addition, display Postscript technology is also integrated in the PDF to achieve consistency in hard copy output and screen display.
After cross-media publishing requirements have been designed and produced, the results of the work can be used for a variety of publishing purposes, namely one production and multiple uses. Cross-media publishing also requires that the production content has an adaptive processing feature that is consistent with the purpose of the publication, that is, the relevant parameters can be set for a specific publication purpose to suit the recording technology and media used by the publication.
First, cross-media publishing and its basic requirements The basic task of cross-media publishing can be summarized as "the processing, use and storage of data files can adapt to any kind of output", this basic task can also be used as a definition of the concept of cross-media use.
From the definition of cross-media, we can see that it not only sums up and summarizes the relationship and technical characteristics of digital prepress and digital printing, but also reflects the new requirements put forward by the ever-developing social needs for print publishing and electronic publishing: It also expresses the broad applicability of this concept, that is, the cross-media concept is the basic requirement for the cross-use of traditional publishing, electronic publishing and web publishing content. Cross-media publishing requires user-designed content to have certain basic characteristics.
1. The content of the adaptive processing content of the content needs to be finished after it is produced. With the advent of electronic publishing systems, the professional knowledge requirements of operators have been reduced, and more and more people are engaged in the production of publications. However, there are misunderstandings on the fundamental issue of significant differences between production and finalization. Design and production are only the preliminary work for the completion of the dissemination of content, during which it may not be necessary to take into account the use of the content and the recording medium, but it is therefore not appropriate to ignore the importance of the final draft. After the design and production are completed, it should be targeted at a specific dissemination method and according to the recording technology and recording medium to be used for targeted processing. This process is called finalization. After the concept of cross-media is proposed, the final draft becomes more important.
Taking the production content for a print job as an example, the page should have adaptive processing features for recording information using a combination of paper, ink, printing press, and a specific printing process after being processed. For example, the current page should be converted to the CMYK color space in other color spaces (this process is also referred to as color separation in the digital prepress process), to compensate for the lack of accuracy of the printing press and plate to produce overprinting. The content is used for trapping. Different screening parameters need to be selected for the quality requirements and copying requirements of the printed matter. On the relevant pages, bite marks, cutting marks, signal bars, etc. are provided to facilitate the printing plate installation, cutting and controlling the printing quality, etc. .
2. Modifying everything in the world is in the process of development, and customer requirements may change. In addition, the design and production of good content can not be without errors, such as text input errors, graphical expression errors. For this reason, cross-media publishing requires that the produced content be edited and corrected before output to reduce losses and create favorable conditions for cross-media publishing.
3. Data format conversion applies to the production process of digital content and digital technology for publication content. Different publishing formats require different digital file formats, depending on the nature of the recording media and the mode of transmission. Therefore, after the content is produced, the data format conversion should be performed as required. For example, the documents used for printing and publishing are converted into Postscript, EPS or PDF formats, and the documents used for network publishing are converted into HTML formats.
From the basic requirements for cross-media mentioned above, effective implementation of cross-media is not enough due to traditional output technologies. It calls for new output technologies, such as Adobe's successful development based on Postscript Level 3 and PDF technologies. SUPRA structure. (To be continued)
