Handling of common faults in film output
Author: Lin water In computer layout, the output of film (including laser printer output sulfate paper) must be sent out. Because there are many types of graphic processing and typesetting software, typesetting software, fonts, etc., and different typesetting methods, fonts, etc., their typesetting is different. Although various graphic processing and typesetting softwares are currently better Compatibility but not completely without problems. Due to the influence of various factors, problems such as missing characters, misplaced characters, garbled characters, and image distortions sometimes occur in the layout. This requires the production and output operators to be familiar with the commonly used software. Master the characteristics of each layout in the production and Pay attention when outputting. 1. At present, in addition to the common Founder system, Word and other software, some graphic processing and typesetting software cannot thicken the text, because it will cause ghosting of the edges of the text (Chinese) and affect the clarity of the text output. Therefore, it is best not to bold the text when using these software. If you need bold fonts, you can use fonts with thicker lines. In addition, there are many fonts in computers today, such as PS characters, TureType characters, Bitmap characters, etc. There are also a variety of fonts in graphic processing and typesetting software that are more convenient to use. The font is also very rich. However, when selecting fonts, it should be noted that if the fonts have been installed in the output device such as imagesetter, if they are not installed, they can be downloaded from the network before the layout should be installed and then sent. For example, when using a TureType font that is not installed in the imagesetter, after downloading the font from the Internet, the OS 8.5 and OS 8.6 systems have some problems with the download processing. Sometimes there will be a problem of missing strokes, so after downloading, you can output a large sample Try it with a small amount of film, and then send it out in large quantities after it is completely correct to avoid wasting materials and time. In addition, because the fonts of different fonts are different, and are not fully compatible. To distinguish between different emission characteristics. Fonts that meet different output conditions. However, in a layout system, a commonly used font should be selected as the system default font, unless special needs usually do not open different fonts at the same time or open multiple fonts at the same time, so as not to cause font errors during output. For font types of the same type and different types that cannot be mixed, try to install relevant fonts that can be used to save output space. It should be noted that the server font cannot be loaded but the server font is available if necessary (slow speed). When the font is replaced, it should be directly selected again when confirmed. Otherwise, when the font is reset, the text and punctuation marks will cause the position to move. It is best not to use text effects for very small text, such as italic, hollow, and underline. Because the font attributes and default options of different computers are different, such as when files are converted between each other, it is necessary to convert the default kerning of the PC to the normal kerning of the Mac to avoid errors. Different versions such as Chinese version, Chinese version, and English version have different support procedures for double-byte Chinese, so pay special attention to the layout. The same word and the difference in different versions will cause the output and printing to be different. For example, the punctuation marks in the old and new models of Hanyi are square and round. The old fonts can not be one-to-one correspondence will cause garbled misplacement during download. Straight punctuation marks will cause problems in some systems, and you must use the area code to enter special symbols to solve. When inputting Chinese or English or when Chinese and English are mixed, it is best to use Chinese and English input methods and Chinese and English fonts respectively, otherwise it is easy to make English words more Chinese. In addition, downloading fonts should be avoided when using the most commonly used PC platform typesetting software for output, because the software (especially pirated software) itself is not perfect enough. It often appears garbled when using downloaded fonts for layout malfunction. The same font can be installed on the PC platform and RIP at the same time, and you should try it out before sending it. For the very frequently used Word typesetting software. When outputting pages made with Word software on the PC platform, pay attention to setting the pages to monochrome pages, because the color pages made with Word software are all in RGB mode, and the output is generally CMYK mode, so it often appears during output Some problems, even when separating colors in RIP, often have errors. 2. Because of the imprinting function sometimes used in image processing. And some software also has these functions. For example, the black version in Pagemaker will be automatically stamped. But some color blocks and lines need to be made by yourself: Freehand, Illustrator and other software need to set black version imprint. therefore. Check the imprint function before issuing. For other colors that need to be imprinted in the software, they need to be set at the time of production. However, it should be noted that when setting the black plate imprinting, it is necessary to check the gray areas that cannot be imprinted. For pages made with Illustrator software, because the speed of direct layout is slow, and sometimes the page size will change, you can save it as an EPS file and place it in Pagemaker to make the layout faster. But it should be noted that Pagemaker has no imprint effect, so. This method cannot be chosen uniformly, but should be selected according to the specific situation of the page. 3. Now some typesetting software has the functions of rotating, cropping and scaling the image, but because rotating the image in the typesetting software will not only occupy more memory but also increase the calculation amount at the time of layout, making the layout time increase. therefore. It is best not to rotate, crop or scale the image in the typesetting software. In addition, the image display in the typesetting software is roughly cropped and the reduced image is inaccurate and this method of cutting and reducing does not reduce the amount of information in the image, and it cannot shorten the layout time: enlarging the image in the typesetting software will affect the image quality . Therefore, it is best to complete the rotation, cropping and scaling of the image in the scanning and image processing software. In addition, it should be noted that in the typesetting process of individual typesetting software (especially mixed Chinese and English), you can not use line alignment and forced line alignment, because the function of these typesetting software is not complete, so the page is often displayed on the screen when it is forcibly produced. But the actual output is a different matter. 4. In the storage of images. There are currently many formats, each with its own characteristics. Choose the storage format according to the specific situation to avoid errors. Such as the commonly used TIFF image storage format, because of the large amount of stored information. Some RIPs will have errors when processing TIFF images with a large amount of information sent by the imposition software. Therefore, it is better to store images with a large amount of information in EPS format before placing them in the send. In addition. Some RIP will have a very obvious jump when processing the 0-100% gradient issued from Pagemaker 6.5 software. At this time, you can use the method of adding noise to the gradient image in Photosho p to solve this problem.
