Adobe's portable document format (PDF) for the publishing industry to solve the many problems. Pre-press companies in particular are playing such a superiority of standard data formats and, where possible, to use it. Unlike other digital file format, it does not need to text files, fonts, image files or separate vector map. In Acrobat Distiller to generate PDF, when will they all merged into this document. Because the media has nothing to do with the operating system and can be a PDF as a "virtual work packages", and put the contents of all the necessary pre-press added. As a goal-oriented format, PDF has nothing to do with the resolution. Necessary, it can output for the printing plate or film output and other high-end output, data compression can also be used for Down sampling the Internet or CD-ROM and so on. Adobe had a paperless office as the development of data formats PDF, but it was soon found in the pre-press environment, the use of it. For example, PDF data compression has great advantages. It was a version in Beijing a few bytes of PostScript data reduced to a few hundreds of bytes. Stuttgart, Germany, for example, the printing company SuDwest-Rolle production samples of each version of the company to 1.8GB of data reduced to 140MB. This is not only important to the archive, the network for editing and transmission of data is also very important. Choice of products of course, like every new technology, like, PDF has its own shortcomings. Including some technical defects, (and we look forward to) Adobe in a future version will address these issues. Despite the non-technical issues are usually more difficult, many users have become familiar with the document processing and other aspects of the specificity of the format. In the PDF workflow stage, will inevitably produce a variety of production problems. Because of the potential of PDF, printing equipment and software developers have the advantages of its introduction of their workflow. Agfa Apogee first to enter the market, and are CreoScitex and Heidelberg Prinergy as the basis of PDF. These work processes is an important feature of all production steps are the same as those from a single user interface will start to the next step, and operators do not interfere too much. Manufacturers of integrated workflow to solve these problems. For example, a complete Agfa Apogee workflow system: Apogee Creat (used to generate PDF's Agfa Normalizer), Apogee Pilot workflow central control panel), Apogee PDF-RIP (the interpretation and output file) , Apogee Prindrive (output management) and Apogee InkDrive (for automated printing and binding tools generate CIP4 data). Agfa's sales of the entire workflow module is priced at 50,000 U.S. dollars, including five Normalizer permits, but does not include hardware. Prinergy is a modular system. It includes Normalizer (Adobe Distiller of OEM products) high-resolution and low resolution Render, Archive module and Trapping Engine proofer drive module. There are other components of the Prinergy Color Management software, PrintLink (generated CIP4 data module), and workflow system for at least five licenses. Surveillance in the background there is a central database of the entire process. The basic system does not include the hardware, the price of about 56,000 U.S. dollars. For users the advantages of such systems is obvious. It has a single user interface, all components of a single system design, all of which are the only supplier of continuous improvement. Generally avoids incompatibilities between modules, in the training of the vendors, the user will be able to obtain consistent quality of output. All production steps - from the generation of PDF documents, pre-screening, PDF document editing and revision, color adjustment, color control and the overprint in the integrated system control; to operator error reduced to a minimum. Provide these security features so that the income of many manufacturers. There are a lot of license fees (including the upgrade fees, additional hardware costs and service contracts, etc.). This allows the use of high-end workflow process has become spent. Perhaps worse, these "hidden" so that the estimated cost of a like! Prinergy or Apogee budget system has become a difficult job for him. Therefore, many users decide not to purchase a complete system, with different products into their own system of work. This is clearly the advantage of low start-up costs, but the availability of staff expertise and the high cost of training, they must learn to understand each tool and the entire workflow. In addition, they need to develop and strengthen a variety of software related to the parameters used in the agreement, the development of such steps and file name. However, if designed appropriately, it is possible to be flexible and proactive and cost-effective. As high-end system, as can the combination of the PDF process itself is broken down into steps. Including the generation of PDF documents, pre-screen, edit documents, edit, and color conversion, re-mix, overprint control, such as color separation and output. This article will analyze each step used in a number of professional tools. |
