The application of network technology in printing is mainly to solve the problem of sharing and transmission of pre-press data files. In the field of printing, the most common applications are LAN and Internet. In addition, satellite transmission technology is also an efficient, stable and secure Internet remote prepress data transmission method, mainly used for remote remote printing of newspapers. Here, based on years of experience, the author summarizes the following application techniques of network technology in printing for peer reference.
LAN application skills
1. Efficient and reasonable local area network is the key
Before building a LAN, you should plan your network topology and select network devices under this framework. The star network topology is currently the best networking method. The choice of network equipment is very critical. The data exchange equipment determines the transmission efficiency of data in the network; the optimal configuration of data sharing equipment and the optimal configuration of network lines can prevent large-scale network congestion.
2. Create a unified path of the text library and image library
In the process of using the local area network, all the prepressed text files that need to be called should be placed in the same file library, and all the images to be called should be placed in the same image file library. Pay special attention to the fact that image files cannot be renamed.
3. Use the network mapping function correctly
The drive on the appropriate computer should be selected for mapping, for example, a drive on the computer that holds the image file and prepares the prepress output file can be mapped to the computer that controls the output.
4. Correctly set network settings parameters and virtual memory in the Windows operating system
The network setting parameters mainly include communication protocol, device and data sharing, access rights, etc., which need to be set correctly; in the prepress layout and output software, the virtual memory is usually set to twice the physical memory of the computer host.
5. The network application related parameters must be correctly set in the prepress layout and output software.
Take Founder Feiteng typesetting and Founder RIP output software as an example. In Founder Feiteng typesetting software, you can not include the picture file in the PS (or EPS) output file during the routing, by checking "In the sending parameter setting window" Collect image data to "option, so that the image file in the PS file of the release row is automatically saved to the save path of the PS file generated after the release; when using the Founder RIP output software for output, the RIP parameter setting must be clearly indicated. The location of the image saved after the layout software is distributed, and check the "Ignore the machine name of the image path" option.
6. Reasonable application of hardware resources during layout and output
Other programs must be run as little as possible when making layout or output operations.
7. Don't just turn off the computer that is turned on in the LAN.
Do not turn off the computer that is turned on in the LAN, especially the computer associated with the output file, until the final prepress output is complete.
8. Reasonable use of poor performance computers
For some poorly performing computers, they should be separated from some key prepress processing links, placed in a network segment or network workgroup, using a unified operating system, and only with the entire network. The file server is contacted.
9. Pay attention to technical adjustment and technical transformation of prepress network system
The technical adjustment and technical transformation of the prepress network system can focus on the line, and minimize the number of lines that need to transmit large amounts of information in the system.
10. Do a good job in the daily maintenance of the LAN
Important files and information throughout the system should be protected, set up with strict access rights, and backed up the system and important files. In addition, equipment should be managed in a unified manner and system resources should be allocated reasonably.
FTP file transfer application skills
1. Do a good job of communication before transmission
Be sure to inform the recipient of the basics of the file before uploading the pre-press output file.
2. Carefully check the prepress output file
When uploading pre-press output files, it is best to package and compress each pre-press output file separately. At the same time, you should be careful not to lack files, especially the pre-press output files designed and manufactured by Founder Feiteng typesetting software. Image file.
3. Proper file transfer
When uploading the pre-press output file to the FTP file server, it is best to upload the large files one by one, and do not upload multiple large files at the same time to prevent the packet from being dropped. When the layout result is outputted (or output) as an output file in the typesetting software, the entire prepress output file should be split into multiple small files for packaging and compression transmission, provided that the typesetting software must have such a function.
4. Reasonable use of multi-threaded way to upload or download prepress output files
When uploading or downloading prepress output files, you can use multi-threading to increase the speed of uploading or downloading files. However, depending on the amount of file information, it should be determined that the appropriate amount of threads is used or that a single thread is used for uploading or downloading. Sometimes it is not good to upload or download files using the largest amount of threads.
