Analysis of common problems in the output of laser Phototypesetter

the use of laser Phototypesetter for output in the prepress publishing system is the most vulnerable link of the whole prepress publishing system, which should be paid special attention to in use. This article will take the use of Founder Feiteng newspaper typesetting and founder pspnt output software as examples to introduce the problems that are easy to occur when using image setter for network output and the prevention and treatment methods. Of course, the following problems are generally suitable for most other output devices, not only laser imagesetters, but also digital proofing devices

the main problems and causes when using the Phototypesetter for output in the prepress publishing system network are as follows:

(1) the typesetting operator selected the "ignore image path" option in the "typesetting" option in the "file" menu of the main window in Feiteng electronic typesetting software when publishing a newspaper, In this newspaper, the food packaging and catering industry in the city issued a strong protest, including the image files discharged through the upper neighbor. The selection of the "ignore image path" option made the PS files unable to find the image file path when outputting, resulting in the lack of image file information when outputting

(2) during the output operation, the imagesetter operator selected the option of "machine ignoring image path" in the "rip parameters" option of the "parameter template" window of pspnt. When interpreting PS files, the path of image files cannot be found, resulting in the lack of image file information during output

(3) when pspnt is used to interpret the PS file, the path of the image file does not exist at all. For example, the microcomputer storing the image file library has been turned off, and the microcomputer hard disk drive storing the image file library is not shared. In this case, when rip interprets the version, the system cannot find the path of the image file, resulting in the loss of image file information when outputting

(4) there may be too many image path sources when the newspaper typesetter is in the local area. Sometimes it may come from the image files on the microcomputers of different working groups in the local area. When interpreting this newspaper with pspnt, due to the long time to find the path of the image file, it takes up a lot of microcomputer system resources, which affects other newspapers being output by the imagesetter when interpreting this newspaper, The newspaper in the process of output is suddenly interrupted. At this time, the operator has to manually remove the film and then output it again

(5) when typesetting is carried out in the local area, the images discharged may sometimes be image files on other microcomputers. The path during typesetting is to find an image file through the upper neighbor for typesetting. After typesetting, when interpreting the layout through pspnt, the information of the image file discharged through the upper neighbor may not be found. When outputting, because the images of the layout are not all output, the film will be re produced, resulting in a waste of film

the reason for this situation may be that some images are discharged in the way of upper neighbor when discharging image files, while some image files are not discharged in the way of upper neighbor. For example, if the image files stored on the disk of the typesetting microcomputer are not found and typeset in this way, the images may not come out when output; It may also be that the typesetting file may be opened in the way of the above neighbor during typesetting, but when modifying the layout, it is not opened in the way of the upper neighbor. When the layout modified in this way is output after publishing, it is likely that the image will not appear; Another possibility is that when giving the departure route, you don't choose the way of neighbors to give the departure route, which is most likely to cause the lack of images in the output layout

the abnormal output caused by the above laser imagesetters during operation is caused by the improper typesetting operation of image files during typesetting, or the unexpected situation when pspnt interprets the information of image files, that is, the problems are related to the images in the newspaper, and most of them will cause the lack of image information in the film output by the laser Imagesetter, Cause waste of film or system interruption.

(6) when outputting film locally, sometimes it is impossible to enter a working group to find the microcomputer for typesetting at all, or even if the microcomputer for typesetting is found, it cannot receive the layout information normally. The reason for this situation may be that there is a network failure

for example, there is a problem with the card on the data switch, hub or microcomputer; It may also be that the configuration of network equipment is relatively low, the amount of information transmitted is not large, and the transmission speed is not fast enough. For some newspaper pages with large amount of information, if the data information flow of the hub of the working group or the microcomputer card that stores the information of this page is not large, the microcomputer used to control the output simply cannot interpret the large amount of information pages normally, so there is no need to say the film; It is also possible that the network setting parameters are incorrect and the network cannot be started

another important reason is that the data switch or hub and other network devices in the network system are not turned on at all, or these network devices are powered on after starting the microcomputer. If so, the microcomputer system cannot find the upper neighbor. Sometimes it needs to wait for a period of time to find the upper neighbor, and sometimes it can only find the upper neighbor after the network device is turned on and restarting the microcomputer. It is also possible that the PS file path of the newspaper page is not shared when the typesetting computer is used to send and arrange the newspaper page, and the PS file required to be output by the imagesetter cannot be found in the upper neighbor

the prevention and treatment methods for the problems arising from the output of the Phototypesetter in the prepress publishing system network mainly include the following aspects:

(1) when typesetting the newspaper, the typesetting operator should carefully observe the relevant image typesetting options in each typesetting window, and first set various typesetting or publishing parameters correctly before typesetting

(2) the operator of the laser Phototypesetter should understand the workflow of pspnt. The output of a newspaper must first be explained by explaining the arranged newspaper, developing new material technology, consulting, financing, information, testing, standards and other services, finding the path into the image file and invoking the discharged text information in the output font. Only after ensuring that there is no error can the Phototypesetter officially start to produce films. With an understanding of this workflow, the operator can timely avoid unnecessary waste or adverse effects caused by plate making and printing of incomplete information due to the lack of image or text information

(3) the operator who operates the laser Imagesetter should also set the parameters related to image output of pspnt correctly. Generally, it is very important not to select the "ignore" option in the "rip parameters" option in the "parameter template" window. Of course, the "ignore" option is not only for images, but also for text messages in newspapers. If this option is not selected, the text in the report cannot pass the interpretation when 100 pieces of equipment can increase the company's daily output to 1 ton. If this option is selected, the missing font will be automatically replaced by regular script when pspnt is used to interpret the report, and the output can be carried out normally

in addition, this option also controls the supplementary word information in the newspaper. If the supplementary word library is missing in the output word library and the "ignore" option is not selected, the layout cannot be interpreted. Only by selecting the "ignore" option can the pspnt interpretation be skipped, and then proceed to the following operations. When using pspnt to interpret the layout, if the "ignore" option has to be selected due to text information, it is best to display the lattice for the interpreted layout, and carefully observe the entire layout to see whether there is a lack of images. At the same time, you can also look at the information window when interpreting the layout, and make use of the lightweight design materials of all automobiles: high-strength steel, light alloy After analyzing the information displayed by the composite material and confirming that it is correct, the film can be output

(4) for the typesetting of image files, corresponding image file libraries should be established. It is best to fix a unified path for the image file library, so that pspnt can easily find the source of image files and ensure that image information is not lost during output. For the image files discharged through the upper neighbor, the typesetting operator should also send the arranged layout to a fixed path (hard disk drive) through the upper neighbor. For a newspaper, if the image file is discharged in the way of upper neighbor, other image files in any path should be discharged into all images in the way of upper neighbor

(5) for the image file discharged through the upper neighbor, when using pspnt interpretation, you can give the exact path to the image file in the "image path" column of the "rip parameter" option in the "parameter setting" option in the "parameter template" window. When the image file has multiple path sources, you can write multiple different paths into the "image path" column at the same time. If the scheduling is performed through the upper neighbor, the pspnt cannot explain normally at this time. In fact, it is a last resort to choose the above method. (end)
