Computer Graphic Design and Prepress Graphic Processing 500 Questions (25-30)

25. What is the composition of computer design system? What software and hardware are required for the simplest design system?

A: The software of the color desktop publishing system can realize many creative design functions, and can complete the graphic design work done by former professional printers. Designers have gradually begun to use computer for graphic design and gradually become popular. The use of computers for graphic design has become a common method for graphic designers. Some people refer to the graphic design personnel of graphic arts as the computer design system for the software and hardware of the graphic design. It is slightly different from the color desktop publishing system, and does not require such complete and large-scale equipment. The software and hardware required for the most simple design system are: hardware: a flatbed scanner, a fast computing computer, a color printer, and a large-capacity disk storage (used to send the generated electronic files to the output center. Output). Software: One of image processing software, vector graphics software, and typesetting software. The computer design system can be used to complete all the work of the graphic design. After the electronic files are formed, they can be processed and processed outside. This eliminates the need for large equipment such as laser imagesetters.

26. Why does a computer design system require large memory? What are the commonly used large-capacity memories?

A: Many photos or computer-generated images are used in the design. Due to the need of print output, the resolution of images is usually high, about 300 dpi, so the images take up a lot of disk space. For example, a 4K imposition file generally has more than 100M of all stored files. The commonly used 3.5-inch floppy disk does not meet the requirements for storing images, so large-capacity memory is used. Commonly-used large-capacity memories are: 1 magneto-optic (MO) drives, with 230M and 640M or larger discs. 2 active hard disk. 3ZIP (100M) drive. 4 rewritable discs.

27. What are the workflows for prepress design or computer design?

A: The general workflow has the following basic processes: clear design and printing requirements, acceptance of customer data; design: including input of text, images, ideas, imposition; out of black and white or color proofs, allowing customers to modify; according to the revised school draft Re-release the school draft, allow the customer to modify until the finalization; let the customer sign the film; pre-press proofing; send the proofing, let the customer see if there is a problem, if no problem, let the customer sign. All work on prepress design is completed. If there is a problem in the proofing, you have to change it and re-export the film.

28. What is the workflow for designing a computer design system?

A: The workflow in the design system is as follows: First, the original is scanned according to the final size of the image, and the image is adjusted in the image software, and at the same time, some creative design work can be completed. The typesetting design work in graphics or typesetting software includes inputting text, drawing graphics, and placing images. After the client finalizes the document, the document is sent to the output center for output of the film. The laser imagesetter works with the Postscript language. The layout is described by the RIP (Raster Image Processor) as a bitmap and divided into four colors: C (Cyan), M (Magenta), Y (Yellow), and K (Black). sheet. If the final design requirement is not an output film, but a large-scale color inkjet sample, then the inkjet printer output is sufficient.

29. What installation work is required to make the simplest design system work?

Answer: 1 The installation of the computer host includes installing the operating system and let the computer work normally. 2 fonts installed for the design. The installation of the font used on the computer: PC can add fonts to the font file, MAC machine directly drag the font into the font folder. Do not install too many fonts, otherwise the application software will open and run slowly, and the font selection will be more troublesome. Laser Printer Font Installation: For PS laser printers, print fonts can be mounted on a hard disk attached to it. 3 Installation of application software: Install one each of image software, graphics software and typesetting software. Follow the software installation procedure when installing. Some softwares need to be restarted after installation to use. 4 Scanner Driver Installation: There are two scanner driver installation methods: one is independent installation, and the other is hanging in Photoshop below boot. The method installed in Photoshop is: Step 1: Install the driver software and select the folder where Photoshop is installed. The second step: After the installation is complete, open File\lmport\TwainSelect in Photoshop, you can see the dialog box, select the scanner driver software name. Step 3: The selected scanner driver software will automatically appear in the File\lmport menu and the scanner can be started after selection. 5 Color Printer Driver Installation: Installation Method Follow the installation requirements. It should be noted that if the computer system has been changed, some of the installation work will have to be carried out again.

30. Color computer design is good with Apple Computer? Or a good PC?

A: The initial pre-press design software was developed and used on the MAC. With the introduction and development of the Windows graphical user interface, many softwares have slowly been ported to the PC. Today's graphic design software has two versions of the platform, so there are no restrictions on the use of software. As for hardware, the price of MAC is higher than PC (especially PC compatible). However, from the perspective of color reproduction, color management, and graphic processing technologies, the use of PCs is weaker than that of MACs. Therefore, it is more suitable for graphic designers to use MAC. Because of the following reasons: MAC operating interface is more concise, the operation is more "fool". The color management on the MAC is more complete and the colors displayed on the display are closer to reality. The graphic processing technology of the MAC machine is more stable and there is less chance of mistakes in the work. Of course, if you have rich experience in color, you can use the data to work and you can also use a PC. The use of PCs is relatively less investment.
