Frequently Asked Questions about Output of Imagesetters in Network and Countermeasures

There are mainly the following aspects in the prevention and handling of the problems that arise when using the imagesetter in the prepress publishing system network:

(1) When the typesetting operator tries to typeset a newsprint, he should carefully observe the related image typesetting options in each typesetting window. First, set the various typesetting or publishing parameters correctly, and then perform the typesetting.

(2) The operator of the laser imagesetter should understand the workflow of the PSPNT. The output of a newsprint must first be interpreted by the ranked newspapers to find the path to the image file and recall it in the output font. After the text information was ensured to be correct, the phototypesetting machine was officially started to start filming. For this understanding of the workflow, the operator can promptly avoid filming due to lack of image or text information, causing unnecessary waste or causing incomplete information on the layout of the plate to cause adverse effects.

(3) The operator who operates the laser imagesetter should also set the parameters related to the image output of the PSPNT correctly. Generally, do not “Ignore” the “RIP parameters” option in the parameter setting options in the “Parameter Template” window. It is very important that the options are selected. Of course, the "Ignore" option is not only for images, but also for text information in newspapers. When the font output is missing in the output font, if this item is not selected, the text in the press version cannot be interpreted at the time of interpretation. If this item is selected, the missing font will be used when interpreting the newspaper version with PSPNT. Will be automatically replaced by the body, it can be normal output. In addition, this option also controls the word-replenishment information in the newspaper version. If the output character library lacks the complement word font and the “Ignore” option is not selected, the layout will not be explained, only by selecting the “Ignore” option. Can only skip the explanation of PSPNT, then proceed with the following operations. When using the PSPNT to interpret the layout, when the “Ignore” option has to be selected due to textual information, it is better to display a dot matrix for the well-interpreted layout, and to carefully observe the entire layout to see if there is a missing image. , You can also look at the information window when the layout is explained, analyze the displayed information, and confirm the correctness before performing the film output operation.

(4) For the layout of image files, a corresponding image file library should be established. The image file library is preferably fixed in a unified path, so that the PSPNT can easily find the source of the image file and ensure that the image information is not lost when output. For the image files that are sorted by the network neighbor, the typesetting operator preferably distributes them to a fixed path (hard disk drive) through the network neighbor when the layout is arranged. For a newspaper version that uses the online neighbors to import image files, all other image files in any path should use the network neighborhood to all images.

(5) For image files that are imported through My Network Places, when using PSPNT interpretation, in the "Image Path" column in the "RIP Parameters" option in the "Parameter Settings" option in the "Parameter Template" window, The exact path into the image file, when the image file has multiple path sources, multiple different paths can be written to the Image Path column at the same time. If the posting is performed through the online neighbor, the PSPNT cannot be explained normally. Selecting the above method is a last resort.
(6) When the PSPNT interprets the newspapers in the queue, all microcomputers associated with the typeface images (ie, the microcomputers fed into the image source) cannot be turned off, and the hard disk drives for storing the images must be shared to ensure that When interpreting the layout, you can confirm the images you have placed.

Only after PSPNT interprets all the newspapers in good order and displays the dot matrix to confirm that the image is correct, the microcomputer with the image can be turned off. If the images to be imported come from multiple PCs, these PCs cannot be turned off when the PSPNT interprets the layout and prepares to output the film. This is particularly important. Many problems are related to this.

(7) The typesetting operator should pay attention to the name of the image file when the image is not in the same path, because the image is stored in the hard disk drive of different microcomputers in the LAN. After the image editing process the image, it is very important. There may be a phenomenon that the two images are duplicated. When the operator typesets, the file name of one of the images should be modified so that the name of the image file will not appear in the layout, causing PSPNT to explain the layout. I have trouble finding the path to the image.
(8) In the local area network, the output personnel of the newspaper typesetting staff and the laser imagesetter do not usually work in the same place. They should keep in touch before outputting the layout. The typesetting staff should tell the layout machine operator about the layout information. For example, the file name, storage path, layout, layout, layout, layout, layout, layout, layout, layout, layout, layout, layout, layout, layout, layout, layout, layout, layout, layout, layout, layout, layout, layout, layout, layout, etc., in order for the operator of the layout machine to have a general understanding of the printed layout. To avoid mistakes in the layout of the output, in particular, to avoid reprinting the plate that had been plated on the previous day, which was printed a few days ago, for plate making, with serious adverse consequences.

(9) The management personnel of the internal LAN should pay attention to strengthening network management to ensure the normal operation of the network. At the same time, it is necessary to regularly perform necessary technical training for various operators on the network so that the operators can understand some of the network operation skills. Improve the quality of operators. Network management technicians should regularly check the working conditions of network equipment. Problems should be dealt with in a timely manner. Strengthen the network management, set up certain authority on each computer in the local area network, make every operator operate within one's own authority range, do not let the operator surpass the authority, in order to cause greater losses. In particular, some key equipments in the entire LAN, such as servers and microcomputers that control output, should pay attention to strengthening management, and should not allow ordinary operators to access them casually.

If the computer that controls the output is set to the authority, then any operator other than the image-setter operator cannot access the microcomputer, so that the artificial destruction or abnormal use of these microcomputers can be avoided, and the resulting waste film phenomenon can be eliminated. Completely eliminated. At the same time, when configuring or allocating equipment, it is necessary to ensure that the network equipment in the working group related to the output film has good performance, high data transmission capability and fast data transmission speed, ensuring a large amount of information in the newspaper layout. Normal output. Various operators should also pay attention to strengthening learning in daily work, develop good network operation habits, and avoid mistakes in network operations. When accessing other microcomputers on the Internet, do not arbitrarily delete other things on the microcomputer, causing network defects. . In addition, when the operator uses the computer on the network, he should first open the network device, and then run the computer on the network when the network device is working normally, so as to avoid being unable to find the network neighbor.

(10) All microcomputers running on the internal LAN shall not shut down any open computers on the network when the imagesetter has not completed the interpretation of the newspaper layout of the day with PSPNT and have confirmed that the layout is correct. The computer relating to the layout of the newspapers in question must not be closed, so as to avoid the lack of information when the PSPNT interprets the layout, so that the output of the layout is incomplete. The most effective way to avoid this phenomenon is to strengthen the contact between various operators at any time. Generally, they can be resolved through the internal phone attached to the internal LAN or by posting messages on the internal network.

In addition, the best way to avoid the occurrence of system resource occupied by the network neighbor due to the shutdown of the computer in the network is to use the disk mapping function on the hard disk drive controlling the output of the desired hard disk drive for storing PS files. These hard disk drives are mapped to microcomputers that control the output. Instead of using My Network Places to find all the open microcomputers on the entire network, as long as the computer on which the hard disk drive is mapped is open, the use of disk mapping is to find the computer directly. A certain hard disk drive of a microcomputer, this operation reduces the time and system resources that the microcomputer uses to find the network, and the operation speed is fast and reliable. However, using the disk mapping function, a problem must be solved: when the layout is being dispatched, the network neighbor should be sent to a fixed hard disk drive of a certain computer to avoid mapping on the output-controlled microcomputer. Many hard disk drives cause confusion in the network. It is best to set up a special distribution path for each of the daily and evening newspapers. When publishing, it is necessary to use Network Neighborhood to publish, even if it is a PS file that is sent to the local computer. After solving this problem, the function of disk mapping is very helpful to the output of the newspaper layout, which can prevent the system from being interrupted and appear abnormal operation.

(11) For the phototypewriter operator, when explaining the layout, it is necessary to wait until the layout has been completely discharged before explaining the layout. When the imagesetter is outputting film, do not open some programs that have nothing to do with the output. That is, do not open two or more programs at the same time. Do not install unnecessary programs on the control output microcomputer; do not explain the The layout has too many operations at the same time, while the film is being released, while explaining the layout of the other pages. At the same time, some layouts are displayed on the screen. Sometimes multi-step operation is a bad thing. Things must be done one by one. Do not worry about it. , slowly to do it slowly.

The microcomputer controlling the output also does not often use the network neighbor to access too many network microcomputers and occupy a large amount of system resources. The most important thing is that the operators of the imagesetter should display the dot matrix on the well-interpreted layout to confirm whether the newspaper layout is correct or not. For typesetting operators, do not use the network neighbor too much to access the computer on the network during operation to avoid network conflicts. Try to open as few windows as possible during typesetting, not to mention Internet, playing games, watching movies, or listening to music, etc. Do not arbitrarily turn off the microcomputer or restart the computer to avoid system interruption when the computer controlling the output is interpreting the layout. You should try to avoid frequent crashes. After the newspapers are well-arranged, the newspapers in the queue should be sent to a fixed output path. Do not change the delivery path, which causes the operators of the imagesetter to explain that they have not completely modified the layout or have already Published newspaper layout output film, if it is caused by the waste may be enormous, the newspaper will be reprinted. Operators on other networks should also operate within their own limits of authority. Do not override powers and cause network confusion. After the layout operator dispatches the layout, the issued PS file may be stored in a certain path of the server so that the newspaper layout can be saved permanently. In order to save publishing time, the layout operator should wait until this time. After the PS file is interpreted with PSPNT, it is copied to the server so that it does not conflict with the PSPNT explanation page, resulting in system interruption.

(12) When configuring the equipment, the microcomputer for the typesetting and the computer for controlling the output should be configured to a suitable height. In general, the memory should be sufficient. The memory of the microcomputer for controlling the layout on the LAN and the microcomputer for controlling the output should not be less than 128M to ensure that the microcomputer system has sufficient resources. If the system configuration of the microcomputer used for typesetting is high or low, the layout of the layout can be sent to the computer hard disk with a little more memory to ensure the integrity of the layout information when the film is output. Actually, network management technicians can use all microcomputers with higher configuration for typesetting according to the actual situation, but only for microcomputers that perform word processing and general data registry processing, 64M memory is generally sufficient. When configuring the device, you must also pay attention to the configuration of the network device. It is better to use a network device with higher performance to ensure that the transmission of the large amount of typographic layout in the network is not affected. For example: if the network card configured on the PC is low, if the PSPNT is explaining the typesetting layout on the PC, it will often fail.
