What is Chinese character recognition? What are the technical problems?
A: Chinese character recognition is an automatic computer Chinese character input technology. It scans, photographs, or captures the trajectory in real time, and the document or track is automatically recognized by the computer as the corresponding Chinese character and converted into the corresponding Chinese character code. This method can input Chinese characters into the computer without any keyboard Chinese input method. In the design, the printed documents sent by the customer are sometimes used, and the Chinese character recognition method can be used for input, and there is no technical problem. If the original is of good quality, kerning and line spacing, the accuracy rate can reach 95%.
What are the factors affecting the scanning Chinese character recognition method?
A: Now the technology of Chinese character recognition by scanning method is very mature. If the quality of scanned text is good, the accuracy rate can reach over 95%. Sometimes there is a situation with low accuracy. This is mainly because of the following factors: there is line interference in the text, then the recognition rate is low; the kerning of the text is too dense; the line spacing of the text is too dense; The scanning quality is too poor, the word is not clear, and there are many places where the line is drawn. For the above situation, you can remove the interference factor in Photoshop and adjust the kerning and line spacing.
What features should the typesetting software have? What is the difference between it and office word processing software?
A: The typesetting software is designed for the professional typesetting field. It should be able to process text, perform image positioning, draw basic graphics, and support printing reverse image output. The word processing includes the following functions: font, font size setting, English syllable processing when wrapping, and various banned processing, so that the discharged layout meets the grammar requirements. Office word processing software generally has poor processing functions in graphics and images, and does not support reverse image output.
What are the conditions for excellent typesetting software?
A: Generally excellent typesetting software should have the following characteristics: 1 Support PostScript language output. 2 WYSIWYG, the page display results and output results are consistent, including text size, fonts, graphics, etc., the color should be as consistent as possible on the screen display. 3 Openness: The software can be compatible with files of other applications, and the generated files can be accepted and used by other software. 4 for the powerful functions of magazines, advertisements, and newspapers, you can achieve a variety of deformation and cutting, effect production.
What are the commonly used typesetting software? What are the characteristics?
A: The current popular typesetting software includes: PageMaker from Adobe, QuarkX-press from Quark, FIT (Feiteng) from Peking University Founder, Monte typesetting software, and Wenyuange typesetting software. Among them, Page-Maker, FIT and QuarkXpress are more used in typesetting software and have stronger functions. The features of FIT are: Chinese processing function is strong, it can meet various Chinese banned requirements, graphics drawing function is strong, the shading is more, and the transformation function is strong. PageMaker features: PDF and HTML files, layer management, color management, graphic links, and table creation. QuarkXpress features: automatic backup and storage, group page function, EPS output, gradient fill graphics, and more. In view of the above characteristics, the application fields of the three types of typesetting software are as follows: FIT is used in a layout with complicated Chinese characters and complicated graphics. Such as newspapers, periodicals, etc.; PageMaker is used for printing and typesetting, and making electronic publications; QuarkXpress is used for large-scale color magazines with large pictures, few texts, advertisements, albums, etc.
What is TrueType technology? What are the characteristics of TrueType fonts?
A: TrueType is a new mathematical glyph description technology jointly proposed by Apple Computer and Microsoft. It uses mathematical functions to describe the outline of the font outline, including glyph construction, color fill, digital description function, flow condition control, raster processing control, and additional prompt control.
TrueType uses the quadratic B-spline curve and line in geometry to describe the outline of the font. Its characteristics are: TrueType can be used both as a print font and as a screen display; since it is described by the command, it is described by the instruction. Regardless of resolution, the output is always output at the resolution of the printer. Regardless of zooming in or out, the characters are always smooth and do not appear jagged. But compared to PostScript fonts, the quality is worse. Especially when the text is too small, it is not very clear.
What are the characteristics of Bitmap (dot matrix font)? Where is it used?
A: Bitmap fonts are screen fonts that are used for faster display. Its characteristic is: because it is described by dot matrix, it is related to resolution. When zooming in or out, there may be sawtooth. Dot matrix fonts are not smooth when printed and are of poor quality. Generally not used for output.
What are the advantages of TrueType fonts?
A: TrueType fonts have the following advantages:
1 true WYSIWYG font. Because True-Type fonts support almost all output devices, they can be output at the resolution of the device, whether on screens, laser printers, laser imagesetters, or color inkjet printers, so the output is smooth.
2 supports font embedding technology. When saving, all the TrueType fonts used in the file can be stored in the file by embedding, so that all the fonts in the entire file can be easily transferred to other computers. Embedding technology ensures that computers that do not have the appropriate fonts installed can print in their original format in their original format.
3 operating system compatibility. Both the MAC and the PC support TrueType fonts, and both can open the application file directly in the software of the same name without replacing the font.
What is the PostScript language?
A: PostScript is a page description language developed by Adobe. It is an interface language exported from the desktop system to the output device. It is designed to describe images and text. PostScript uses the mathematical formula to describe the image and text on the page, and finally translates it to the desired output through the PostScript decoder (Interpreter), such as displaying it on the screen or outputting it on a printer or laser imagesetter.
Since the software used in the desktop system has image software, graphics software, and typesetting software, their functions are different. When so many softwares work together, they must exchange information according to a certain standard format. Their common standard is the PostScript language. PostScript is the most popular page description language in the world and a de facto industry standard. Its perfect design makes it the choice of multiple manufacturers' equipment and is supported by numerous software. Almost all prepress output supports PS language, and the success of PS language has made the open electronic publishing system popular in the world.
What are the characteristics of PostScript rumors?
A: The biggest feature of PostScript is the ability to process text, graphics and images. In a page of prints, it may contain various elements such as text, lines, graphics, images, flat screens, etc. PostScript uses a computer data to represent and describe these forms of information, which makes it possible for the layout of graphics and texts to be processed. . With the PostScript standard, digital data exchange is possible between computers of different manufacturers and between devices. It is the basis for the openness of color desktop publishing systems.
Another feature of PostScript is that it avoids the dependence of the layout on the device. As long as it conforms to the PS standard, whether it is made by MAC or PC, you can get the common PS encoded file through the print driver. PS output devices can output correctly according to their own resolution, regardless of the resolution of the device, and have the same structure page.
