3.PDF standardized PDF digital workflow standardization is to file after receiving the first to perform a process. Only standardized documents passed to the back of the normal flow of the production process and output. PDF Standardization's primary role is to input the source files of different formats into a standardized process within the PDF file format, while the document for further pre-flight inspection, usually on the font information, image resolution and color mode checked again. Correct and smooth the results should be generated through the standardization of PDF file contains all the font information page, and all the graphics, images are in 300dpi or higher resolution, color mode of CMYK printing are consistent pattern. (1) page size PDF standardization can reset the size of the input file. If the Kodak Prinergy workflow Refine template in the "Default page size" option, the user can select the page size of the input file itself. Through standardization, it can ignore the page size of the document itself, in the process of redefining the Refine page size, the size needed by the user can customize. And the large version to match and meet the output requirements, a small version of the page size should be established with the large version of the small version of the same size. (2) Font Detection Font issue has been more difficult to solve the prepress processing a. Normalized PDF files must include all the font information, so as to ensure that the font file contents in the back-end output is intact. Standardization process is usually done on the font further examination of the missing fonts are also available when the solution is to interrupt the process of standardization or the use of alternative fonts, font files, depending on user requirements. Generally embedded in the front of the font files or convert into a curve, standardized the font issue process will not occur again. (3) image resolution and color mode detectionOrder t o obtain high-quality prints, usually printed with the image resolution at least 300dpi, but sometimes also can print the specific purposes set different image resolution. Printing of documents for the CMYK color mode mode. Normalization process can check the file in image resolution and color mode, ensure that the requirements to print output. 4. Digital imposition Digital imposition software to print the emergence of completely out of the traditional hand-make-up process, it is the modern digital production processes are necessary components. Imposition hand off the main issue to resolve is that in a forum on how to order a small version by page. Prepress data flow in the transmission process, the digital imposition link determines the living conditions of the large print edition size, printing, cutting lines, sets of alignment, folding line style and location of production control information, the accuracy of these control information passed on to the finishing equipment, printing can be finished to meet the requirements. Current digital workflow or Signastation normally received by the Preps imposition software generates a large version of the program (co-Founder flowing combination of Fangzheng Wen imposition software interaction). Make-up programs to PJTF or JDF file format in which the import process and the smooth flow. Example below to Preps imposition software. (1) binding and printing style Print style determines the binding of the finished product into a large version of the template page order, that is, off hand bound determines the way of style. Preps provides five kinds of binding styles, have the freedom to set, perfect binding, saddle stitching, double and single joint. User requirements based prints can choose a different binding style. Preps Figure 7 shows the binding mode options available.
