What should we pay attention to when printing PDF output

1 Check the font:

the font in the file is divided into embedded (embedded subset) and non embedded (there is no embedded subset behind the font). The servo machine with high speed regulation accuracy, wide range and stable performance drives the ball screw pair to rotate through the synchronous toothed belt reduction system. If there are non embedded fonts in the file, it is recommended that you turn the song (it is recommended to use the method of splicing transparency, which is very safe) and output it. As shown in Figure 1. Add another sentence: the font column is blank after the song is turned

2 Check the image:

first, check whether there is an RGB image and whether this file is embedded in ICC (color management). At this time, it is much simpler and more convenient to use with the help of pitstop plug-in. The command is: window ---- open the pitstop image panel. As shown in Figure 2, it is completely normal and can be safely output. If Figure 3 appears, it is generally because some command errors appear in the process of converting to PDF. You must correct them before outputting them. You can also modify them with the help of pitstop plug-in, but the effect is far less than that of the source file

second, check whether the image has less than 300dpi. The command is: Advanced ----- prepress check ----- configuration file ----- list bitmaps lower than 300ppi ----- execute. Then, if the result is not found, it can be output, "Chen Weihong said. As shown in Figure 3 and Figure 4. If there are problems, the inspection results will be listed one by one

3 Check the color:

check whether there is RGB color and white overprint. In advanced - Prepress check - configuration file - list non CMYK objects advanced - Prepress check - configuration file - list white objects set as overprint, both results are OK. As shown in Figure 5 and Figure 6

4 Don't forget to check the file size

the film can be released boldly after all the above examinations. In addition, it should be noted that the software and plug-in used here is adobeacrobat7.0professionalpitstop_ 6.53。
