(1)EPS file format, also known as PS format with preview images, consists of text files in PostScript language and (optional) low-resolution representative images described in PICT or TIFF format.
(2) The "encapsulation" unit of EPS file format is a page, that is, a page. The EPS file contains only one page description. In this way, if there are 50 pages of publications, 50 EPS files will be generated. Also pay attention. The page size can be determined according to the overall rectangular boundary of the object on the saved page, so it can be used to save a standard page size in typesetting software, or to save a rectangular area of an object with an independent size.
(3) The text part can also be written in ASCII characters (the generated file is large, but it can be modified and checked directly in common editors) or binary numbers (the generated file is small, the processing speed is fast, but it is inconvenient to modify and check).
(4) Although (4)EPS file uses vector description, it can also accommodate dot matrix images, but it does not convert dot matrix images into vector description, but saves all pixel data as a pixel file description. Control parameters for pixel image editing and output, such as contour curve parameters, screening parameters, dot shape, color equipment configuration files of images and color blocks, etc. They are saved separately in PostScript language. For example:
Including halftone screening (including screening parameters)
Include transfer functions (including transfer functions)
PostScript color management (PS color management)
(5) There are many forms of EPS files, such as CMYKEEPS (including the PostScript description of four-color color separation images and an optional low-resolution representative image), RGB EPS and L * A * B EPS. In addition, there are some differences in EPS files generated by different softwares, such as Photoshop EPS, Generic EPS, AI (the software version of IIiustrustrorator in EPS format) and so on. Pay attention to its compatibility when cross-using.
(6)EPS files can carry all the information of fonts related to characters at the same time. If the output system does not have a corresponding Chinese character library, then the text must be converted into graphics to output normally.
Edit this paragraph to print EPS file.
EPS file can carry all the font information related to characters at the same time. If the output system does not have a corresponding Chinese character library, then the text must be converted into graphics to output normally.
In particular, when outputting to a non-PostScript device, only representative images with low resolution can be output. High-resolution output can only be obtained on PostScript output devices. So many times the proof graphics we print are very rough, because we use a non-PostScript printer to print PostScript files. As long as you switch to a PostScript printer, you can print almost perfect graphics.
What is the purpose of editing this paragraph?
EPS file is a comprehensive format among the common exchange formats commonly used in desktop printing systems at present. As far as the current printing industry is concerned, the files generated by this format will not go wrong anywhere, and most professional software will handle them. As far as I know, EPS files can be applied to the typesetting and design of Pagemaker software. EPS file is a good file format, which can bring great convenience to our file exchange.
Edit this paragraph difference
PostScript format (PS format). It is the standard format of PostScript language. It is a multi-page description file composed of ASCII characters (or its binary form) corresponding to PostScript language. Its specialty is to describe vector graphics, but it can also accommodate dot matrix images. PS format is a file format that can be directly output to printing equipment, and its graphic description part is restored to raster image lattice at the specified resolution of printing equipment (phototypesetting equipment). If there is a pixel image, its output resolution is set by application software or output software. This format is the "original" format of PostScript page description language, and its biggest feature is that a PS file can contain many pages with whole chapters and sections.
Compared with PS format, the "encapsulation" unit of EPS file format is one page, that is, one page. The EPS file contains only one page description. In this way, if there are 50 pages of publications, 50 EPS files will be generated. Also pay attention. The page size can be determined according to the overall rectangular boundary of the object on the saved page, so it can be used to save a standard page size in typesetting software, or to save a rectangular area of an object with an independent size.
Like PS format, e PS file can also contain dot matrix images. Although vector description is used, it does not convert dot matrix images into vector description, but saves all pixel data as a pixel file description. Control parameters for pixel image editing and output, such as contour curve parameters, screening parameters, dot shape, color equipment configuration files of images and color blocks, etc. They are saved separately in PostScript language.
Advantages and disadvantages of editing this paragraph
EPS(Encapsulated PostScript) is the most important format in our image processing. It is widely used in graphic and layout design under Mac and PC environments, and printed on PostScript output devices. Almost every painting program and most page layout programs allow you to save EPS documents. In Photoshop, it is converted to EPS format through the put command in the file menu (note: the put command only supports EPS illustrations).
It is suggested that EPS is the best choice when you load a picture into Adobe Illustrator, QuarkXPress and other software. However, because the EPS format is too large in the process of saving images, it is recommended not to use EPS format if only saving images. If your document is to be printed on a printer without PostScript, it is best not to use EPS format to avoid printing problems. You can use TIFF or JPEG format instead.
