Computer Graphic Design and Prepress Graphic Processing 500 Q (31-36)

31. Digital camera image printing will not have any problems?

A: Digital cameras are divided into home-use cameras and professional digital cameras. The professional plate-making digital camera has high resolution, and there is definitely no problem with image quality. The general household digital camera's image can be used for printing should be carefully checked, the easy way is to put into Photoshop to change the resolution to 300dpi, the size meets your requirements, the image is displayed on the screen clear, clear level, then print There should be no problem with it. For example, using KODAK, CD215 to take a RGB color image size of 40.64 × 30.48cm2, resolution 72dpi, converted to 300dpi after the image size is 9.75 × 7.32cm2, slightly smaller than ordinary photo paper. If the final image is about the same size as 9.75 x 7.32 cm2, there is no problem with the printed quality.

32. What is Chinese character recognition? Is there any technical problem now?

A: Chinese character recognition is an automatic computer Chinese character input technique. It scans, photographs the way, or through the real-time collection writing track, the computer automatically recognizes the document or the track as the corresponding Chinese character and turns into the corresponding Chinese character inner code. This method can input Chinese characters into a computer without any keyboard Chinese character input method. In the design, print documents sent by the customer are sometimes used, which can be input using the Chinese character recognition method. There are no technical problems. If the originals are of good quality, kerning, and line spacing are relatively open, the accuracy rate can reach 95%.

33. What are the influencing factors for scanning Chinese character recognition methods?

A: The technology for character recognition through scanning methods is now very mature. If the quality of scanned texts is good, the accuracy rate can reach over 95%. Occasionally there will be cases where the accuracy rate is lower. This is mainly due to the following factors: There is a line noise in the text. At this time, the recognition rate is low; the kerning of the text is too close; the line spacing of the text is too dense; The quality of the scan is poor, the word is unclear, and there are many broken lines. For these situations, you can remove the interference factors in Photoshop and adjust the kerning and line spacing.

34. What functions should the publishing software have? What is the difference between it and office word processing software?

A: The typesetting software is designed for the field of professional typesetting. It should be able to process text, perform image positioning, draw basic graphics, and support the output of printed reverse images. The word processing includes the following functions: font, font size setting, disassembly of syllables in English during line break, and various forbidden platooning processes, so that the discharged layout meets grammar requirements. Office word processing software generally has poor processing functions in graphics and images, and does not support reverse video output.

35. What are the conditions for good typesetting software?

A: Generally good typesetting software should have the following characteristics: 1 Support Postscript language output. 2 WYSIWYG. The page display results are consistent with the output results, including text size, font, graphics, etc. The color should be consistent with the screen display as much as possible. 3 Openness: The software can be compatible with other applications' files, and the generated files can also be accepted and used by other software. 4 For magazines, advertisements, newspapers and powerful functions, you can achieve a variety of deformation cutting, effect production and so on.

36. What are the commonly used typesetting software? What are the characteristics?

A: Currently popular publishing software includes Adobe's PageMaker, Quark's QuarkX-press, Beijing University Founder's FIT (Fiteng), Mengtai's typesetting software, and Wenyuange's typesetting software. Among them, Page-Maker, FIT and QuarkXpress are used in layout software and have strong functions. The functional features of FIT are: strong Chinese processing capabilities, which can satisfy various Chinese forbidden exclusion requirements, strong graphics rendering capabilities, multiple shading, and strong conversion capabilities. PageMaker features: PDF and HTML files can be output, layer management, color management capabilities, graphic links, table production features unique. QuarkXpress features: automatic backup and storage functions, group pages, can output EPS, gradient fill graphics. In view of the above characteristics, the application fields of the three types of typesetting software are as follows: FIT is used for Chinese characters, graphic and text mixed layout. Such as newspapers, periodicals, etc.; PageMaker is used for printing and typesetting, as well as the production of electronic publications; QuarkXpress is used for large-scale color magazines with many pictures and small texts, advertisements, pictures, etc.
