a few years ago, according to the United States Printing Technology Foundation (GATF) statistics, 88% of surveyed enterprises and pre-press printing professionals in dealing with customers to submit PDF file of the trouble, but not the correct approach, 46% of which pass through the PDF practical training, but there are still many problems. So far, there are many printing PDF documents in dealing with obstacles. In this paper, are often encountered in the printing of the issue to talk about. 1. Transparency for the designer, the "transparency" is a very useful tool, but many of the staff of printing on paper with a transparent layer is walking. To this end, the Adobe PostScript 3-based RIPs (raster image processor description page) needs to be improved in order to address the issue of transparency, however, many of today's use of RIP are not able to upgrade to this level. FortunatelyHowever Acrobat 6 can be transparent and pressure, and print output file, or can not be directly output to the RIP. Do not be in dealing with Advanced (Advanced) menu under the Transparency Flattener Preview (transparency pressure and preview) order by confused by this dialog box is used to preview the transparency of the document produced by a variety of other objects, and no image have a real impact, only to be saved as file or print PostScript file format transparency will really be after the pressure level.
main steps are as follows:
(1) Open the "Print (Print)" dialog box, click the "Advanced (Advanced)" option, see "Advanced Print Setup (Advanced Print Settings)" the transparency of the order to press the case. (2) when the move the slider to "raster (raster)" left, all the transparency of the role of the region will be flat, while the vector object into a raster object. (3) will be 300ppi default of "line with the text" of the resolution changed to not less than 1200 ppi, if film output to 2400 dpi, 1200 ppi settings are on low-, medium-resolution printing has more good results. 2. Vector raster image processing into production processes in the creation of PDF file, not to be grating vector graphics processing, usually it will be converted to JPEG format vector file, so when the subsequent re-conversion of the document format, document a considerable degree of quality loss, proposed to use lossless JPEG 2000 format as a format conversion, image compression can make the smallest loss of information. |
