Published information on the Internet, access to information is now almost become a known thing. However, published on the Internet and publishing a book has not yet universal. In this regard, in addition to factors such as the existence of copyright, there are still some technical issues to be resolved, such as: (1) the contents of a book, if published online,more at least as many as hundreds of thousands of words, if the matched image, the number of bytes will increase thousands of times. Broadband Internet has yet to really solve the problem, resulting in slow transmission speed. Because of the Internet, the greater the volume of documentation, the more slow transmission speed. A more than 10 million words, or even millions of words, and illustrated books in the time-line to mass 2 and the financial burden too. (2) different software online documents generated by each other it is difficult to open, even if opened, its contents will be error occurred. And even different versions of the same software to open the file after its content also varies. (3) can not be read cross-platform. Because of different computer operating systems use different software, different core, it does not generate the same file format. (4) as a result of the use of browsers and different versions, the user's display resolution is not the same, it opens the same site on the same page in the content also varies. (5) The language is different from each other during the existence of language barriers. For example, mainland China and Taiwan, Hong Kong region encoding used in different text, often making it difficult for a smooth Internet web pages to read each other. Moreover, even within the same country, the same area, using the same text encoding, on different computers due to the different fonts used, indicating there are differences in the font. This information does not generally cause illness in most people to send, but not allowed to have books on the differences between fonts. With the PDF, and that these problems are solved successfully the development.
one, PDF's features
PDF is an acronym for Portable Document Format, can be translated into Portable Document Format. Because it has to restore the degree of color accuracy, rich image display and easy to search by features such as editing, publishing industry. To sum up, PDF has such characteristics: (1) with compression. It can be the original file format in the transmission, compression can also be the original 1 / 10 ~ 1 / 40 to narrow the specification to send, and keep its contents remain unchanged. As a result of the original documents can be compressed significantly, making the original transmission line is also significant savings of time. (2) the functions of embedded fonts. Not have to worry about after the use of PDF font problems, so can be read cross-platform. No matter what kind of computer used, and regardless of what operating system, which showed the same results, including different parts of the text in different languages, different fonts. (3) PDF to support the ICC and color management Cologync program can ensure the output color image in different computer shown in color consistency. This is difficult to do previously. (4) PDF with security features, ease of correspondence, contracts, digital signatures. PDF of the above-mentioned characteristics of the Internet for books on editing, publishing, printing and distribution to remove the technical obstacles.
Second, PDF pre-press process with publications
1. For the send and receive and manage contributions
Because PDF is a cross-platform file format, so any books that are included in the text, mathematical formulas, illustrations, photographs and other information and layout information may use this file format in the online transmission and viewed on any computer screen. Hence, PDF for the publications of the successful development of a new editing concept. In future, the author of books and manuscripts can color images will include the presentation of information, including PDF documents using the Internet and transmit them to the editorial or publishing house, rather than as now, in the mail at the same time, enclose the draft of the manuscript and the floppy disk pic. This not only saves time but also saves postage, and less error. The Press editorial board, or to edit the scripts can be processed the same way the Internet presentation of the author to modify or proofreading. The author is at this time to see the future gaoyang style at the time of publication, even the images are exactly the same color. Therefore, the future realization of the use of PDF documents to send and receive online contributions can be avoided after the presentation the current editorial board and author of frequent back and forth between, and it can also avoid the loss due to mismanagement or a picture presentation and request to re-author of the embarrassing situation buji.
