The use of laser imagesetters for output in prepress publishing system networks is one of the most problematic aspects of the entire prepress publishing network system, and special attention should be paid in use. This article will use the Founder Feiteng newspaper layout and use the Founder PSPNT output software as an example to introduce the problems that are easy to occur when using an imagesetter for network output and preventive treatment methods. Of course, some of the problems described below are generally suitable for use with most other output devices, not only laser imagesetters, but also digital proofing devices.
The problems that may arise when using the imagesetter in the prepress publishing system network for output and the causes are mainly the following:
(1) The typesetting operator selected the “Ignore image path†option in the “File†menu item in the “File†menu of the main window of the Feitun electronic layout software when publishing a certain newspaper version. In the newspaper layout of this publication, which includes image files that are imported through My Network Places, the “Ignore Image Path†option is selected so that the output PS file cannot find the image file path during output, resulting in missing image files when outputting. information.
(2) During the output operation of the imagesetter's operator, the "Ignore image path machine" option is selected in the "RIP parameters" option of the PSPNT "Parameter Template" window. When the PS file is interpreted, the image file path cannot be found. The resulting output lacks image file information.
(3) When using PSPNT to interpret the issued PS file, the path of the image file does not exist at all. For example, the computer that stores the image file library is closed, the computer hard disk drive that stores the image file library is not shared, and so on. In this case, when the RIP interprets the layout, the system cannot find the image file path, resulting in the loss of the image file information at the time of output.
(4) In the local area network, the path of the images may have too many path layouts. Sometimes it may still come from the image files of different workgroups on the local area network. When using PSPNT to interpret this version of the newspaper, it is looking for The image file path takes a long time and takes up a lot of computer system resources, which affects other newspapers being output by the imagesetter when interpreting the newsprint, causing the newsprint being output to be suddenly interrupted. At this time, the operator has to manually delete the report. Re-output.
(5) Typesetting of newspapers in local area network. The images that may be imported may sometimes be image files on other microcomputers. The path of typesetting is to find a certain image file through the online neighbor to typeset it. After publishing, pass the PSPNT. When interpreting the layout, the information of the image files exported through the network neighbor may not be found, and since the images of the layout are not all output at the time of output, the film will be re-ejected and the film will be wasted. The reason for this may be due to the fact that some images are imported using the network neighbor when they are imported into the image file, and some image files are not imported through the network neighborhood. For example, if the image files stored on the disk of the typesetting microcomputer itself are not found by way of the network neighborhood and are formatted in this manner, there may be images that cannot be output when outputting; or the typesetting file may be When opening a layout, it is opened as a network neighbor. When the layout is changed, the layout file is not opened by the online neighbor. After the layout modified in this way is output after the layout, it is very likely that the image will not come out. There is also a possibility that during the time of publication, when the delivery route is given, the delivery route is not given by the way of selecting the network neighbor, so that the missing picture is most likely to appear in the output layout. The abnormal output caused by the above-mentioned several kinds of laser imagesetters during operation is caused by the incorrect typesetting of the image files in the layout of the newspaper or the accidental situation when PSPNT interprets the image file information. That is, the problems that arise are related to the images in the newspaper edition, and most of them will cause the lack of image information in the film output by the laser photosetter, resulting in the waste of the film or the interruption of the system. 
(6) When outputting film via LAN, sometimes it is impossible to enter a workgroup to find a computer for typesetting or even if a typesetting microcomputer is found, the layout information cannot be normally received. This may be due to the appearance of Network failures, such as problems with data switches, hubs, or network cards on the PC, or the configuration of network devices may be low, the amount of data transmitted is not large, and the transmission speed is not fast enough. For some information, the amount of information is relatively large. In the newspaper layout, if the data traffic of the working group's hub or the microcomputer network card storing the layout information is not large, the microcomputer used to control the output can't explain the large information layout at all, so there is no need to say film; It may be a problem that the network configuration parameters are incorrect, and the network cannot be started. Another important reason is that there are no network devices such as data switches or hubs in the network system, or these network devices are powered on after the computer is started. If this is the case, the network system cannot find the network neighbors. Yes, sometimes it takes a while to find the network neighbor. Sometimes it is only after the network device is turned on. Then restart the computer to find the network neighbor. It is also possible that when the typesetting newspapers are used to arrange and arrange the newspapers in a row, the PS file path of the newspaper layout is not shared, and the PS files output by the imagesetter cannot be found in the online neighbors.
(7) When the photo-composing machine outputs a film, when PSPNT interprets another newspaper, the computer looks for the newspaper version under a certain path on the local area network, but finds it for a while and the result is outputting the same film. Suddenly it will stop. In fact, it will be almost finished. The operator can only manually drop the film and then re-enter the film. A piece of discarded film is affirmative.
The reason for this may be that the previously mentioned network equipment has failed and the network has been interrupted. The PSPNT will use a lot of system resources to find the microcomputer that is actually not found on the output film. Due to the large amount of system resources, the system has no way to output the film, so the output is interrupted. Another reason is that because the newspapers that are to be published have been partially or completely typeset and the films have been exported, it is possible that in this working group some of the computers that are no longer needed are closed by operators or editors, explaining the others. When the PSPNT was interpreting the required layout through the Internet, the PSPNT-based PC system first had to search for the workgroup where the typesetting microcomputer was located via My Network Places, and confirmed that when the PSPNT was used to interpret the layout, the local area network Whether the microcomputers on the working group are all still working, and if there is a computer shutdown in the work group, the system still has to search through the network for those computers that have been turned off and cannot be found at all, because the microcomputer controlling the output is found by the network neighbor. The information of the number of all microcomputers in a working group has been temporarily saved. Sometimes when PSPNT is interpreting the layout, if a newspaper layout to be output is selected back and forth between multiple working groups in the LAN, for example, in a short time Looking for newspapers for the desired output in the daily and evening groups In this way, the computer system that controls the output also has to save the number of computers that include all the computers in different working groups. When the next time the network neighbor uses the other computers, all the computers in the system that are running will have a shutdown. The microcomputer that controls the output also looks for it until it is confirmed that it cannot be found. This search process will occupy system resources. When the microcomputer controlling the output is occupied with system resources, the PSPNT may not work properly due to a shortage of system resources, causing the film being output to be interrupted, resulting in film waste. This situation is the most common and most representative, and sometimes it will cause the waste of multiple films at one time.
(8) When outputting a film through the network, a crash occurred during the search for the desired edition of the newsletter, resulting in an interruption in the output of the film and the occurrence of a discarding phenomenon. The reason for this may be that when a PS file under a certain path (a hard disk drive in a microcomputer) is called, other microcomputers are also accessing the path or are operating on the PS file, for example, This PS file is copied to the server for reservation. This operation violates the rules of network operation. The microcomputer must crash. Sometimes the multiple microcomputers connected with it crash at the same time. If the imagesetter is outputting the film, since it crashes, the film output also It is interrupted. In the network, other microcomputers on the Internet control the output of the relevant information on the microcomputer. At this time, the film is being output. Since the calling information also occupies the computer system resources, it may cause the microcomputer that controls the output to be interrupted or hangs, resulting in wasted film. The phenomenon occurs.
(9) When the layout of the newspapers to be published is all over, the operator of the imagesetter has not yet had time to explain or explain the layout with the PSPNT. At this point, the layout will not be explained at all and it may lead to system interruption. This situation is not often encountered in practical work, but it is also possible.
(10) After the layout on the computer on the local area network has been arranged by the microcomputer, when the output through the imagesetter, sometimes the output of the layout information is incomplete, for example, the lack of image information or text information, if the imagesetter operator does not pay attention , it may output scrap. The reason for this is mainly due to the lack of system resources owned by the microcomputer on the local area network or the lack of system resources owned by a part of the typesetting microcomputer.
Through the LAN typesetting of newspapers, it is impossible to place all the image files and all the layouts on a single computer. For a newspaper layout, there are usually multiple microcomputers. These computers may have image files and sample files. Document library and layout. Because the newspapers adopt news gathering and editing networks, in order to save expenses, the equipments deployed may not always be the highest grades, and the configuration of some microcomputers may be relatively low. For example, the configuration of CPU and memory may be different. Microcomputers for typesetting use parts of computers with lower profile settings, especially those with smaller memory. When outputting on the typeface, it will result in the memory being not enough and causing the loss of layout information when outputting the film.
When a computer that uses a local area network for typesetting stores the issued PS file on a computer, the computer must not only have sufficient resources to maintain its normal operation (for example, ensuring the normal operation of the WIN98 operating system and Founder's typesetting system). The required system resources are also needed, but also have the system resources needed to maintain the network operation and call information on other microcomputers, that is, this microcomputer may have to have two microcomputers (or even multiple microcomputers) can run normally at the same time The system resources are such that the layout information will not be lost when the imagesetter outputs the film.
If the layout is sent to a microcomputer whose system resources are insufficient (mainly refers to a small memory), the PS file of the distribution may lose information, especially if the layout of the image is relatively large, and the layout is output when the imagesetter outputs the layout. Some of the information is gone (generally the image information is mostly lost, especially if the images entered by the network neighbor are not on the same computer as the typesetting file), and the “skylight†will appear on the output film, sometimes it is still large area. . In addition, in the micro-computer for typesetting, there is a problem with the microcomputer system itself, and the system resources of the microcomputer cannot be fully utilized. However, this microcomputer is related to the newspaper version that is stored, and there are files associated with the layout or are directly stored. For layout, in this case, the layout information may not be complete when the issued PS file is output on the imagesetter. Of course, even if there is sufficient system resources, if its system resources are heavily occupied when the imagesetter interprets its PS file, that is, when the computer with sufficient system resources is being used by other computers on the network (such as
