Fourth, film hanging precision Hanging net accuracy is generally referred to as hanging nets. The higher the precision of the netting, the finer the printed products, but it has a greater relationship with paper and ink. If you print on a regular newsprint (newspaper) a picture with a high mesh size, the picture will not only become more exquisite, but will become a mess (miserable). Therefore, you must understand the printing of your printed matter before exporting. What is the use of paper, and then determine the accuracy of the net. General common paper and hanging mesh accuracy: imported coated paper or stickers, etc.: 175-200 lines imported offset paper, etc.: 150-175 lines of ordinary offset paper, etc.: 133-150 lines of newsprint: 100-120 lines to By analogy, the poorer the quality of the paper, the lower the hanging net, and vice versa. Before printing, you must pay attention to the following issues: 4. If pagemaker, WS, Founder, and Illustrator are used, the linked image file must be copied along with the original file. Network point of view Blue: 15 degrees red: 75 degrees yellow: 90 degrees black: 45 degrees What is Postscript? Postscript is a programming language designed specifically for printing graphics and text. It is independent of the media being printed, whether you print on paper, film, or on the screen. It is a page description language, similar to the HTML language. Printing process Prepress refers to the pre-printing work, generally refers to photography, design, production, typesetting, etc.; The middle finger of printing refers to the middle of the printing process, and the process of printing the finished product through the printing press; After printing refers to the printing of the latter part of the work, generally refers to the post-processing of printed materials, including cutting, laminating, die-cutting, paste bags, equipment, etc., used for promotional and packaging printing. Printing elements Paper: There are many types of paper, generally divided into coated paper and uncoated paper. Coated paper generally refers to coated paper (light copper) and matt powder (unluster copper), and is mostly used for color printing; non-coated paper generally refers to offset paper and newsprint, and is generally used for printing stationery, envelopes, and newspapers. Color: Normal prints are embossed by yellow, magenta, cyan, and black, as well as printed spot colors. Post-processing: Post-processing includes many processes, such as bronzing, bumping, etc., which can help improve the quality of printed materials.

1, when the production of more commonly used design and production software, such as pagemaker, etc., like the word as much as possible.
2. The mode of the picture in the text must be CMYK mode, with a minimum accuracy of 300*300 dpi/pixel/inch.
3. Check if the text in the publication is a four-color word. If it is, change it to monochrome 100% black.
5, photoshop file is best psd (unmerged layer) file, in order to facilitate the modification.
6, the font as much as possible using common fonts, such as Founder, Wen Ding. Try not to use rare fonts. If used, coreldraw and Illustrator first convert the text to outline, which avoids the problem that the output center cannot output without such a font. If you have a make-up file, you must copy the make-up file.
7, clearly told the output center print product size, print volume, printing paper, etc., to facilitate the imposition and hanging net.
8, if the two pages are the same, but the black text is different (frequently encountered), then only the first page of the CMYK four-color, and the second page of the K-color can be, so as not to waste, but also save money. If there are only two colors (such as red and black) and the printing requirement is not high, it is only necessary to output it in one color version at the same time, and it is not necessary to divide the output into two colors. Deal with the printing plate. It also saves money.
The layout of the general network is neat, so there will be an angle in the application. For example, in the case of monochrome printing, the angle of the screen is mostly 45 degrees. This is based on the dots printed on this point of view, and is most comfortable for the eyesight. And it is not easy to notice the presence of outlets, which results in continuous graying. As for printing with two or more colors, it is necessary to pay attention to the combination of the angles of the two networks. Otherwise, an unnecessary pattern will be created, which is called "Moier". Usually the difference between the angles of the two nets is 30 degrees, no net collision will occur, so the general two-color printing, the main color or dark color with 45 degrees, light color with 75 degrees, three colors are respectively 45 degrees, 75 degrees, 15 Degrees and other three angles, if it is the four-color printing, they are red with 75 degrees, yellow 90 degrees, green 15 degrees and black 45 degrees. There is no certain limit to these angles. They are changed according to different needs.
Postscript was proposed by Adobe in 1985 and was first applied to Apple's LaserWriter printer. The main goal of Postscript is to provide a device-independent language that can easily describe images. Being device independent means that an image does not need to be described by the characteristics of any specific device (for example, the resolution of the printer), so this description can be used for printing on other Po stscript printers without any modification.
Postscript as a language, has its own set of grammar and formatting rules, if you are interested in this, please visit A ​​dobe company's website, Adobe has a very comprehensive information.
Postscript files are stored as text, similar to HTML files. You can see this by simply opening a Postscript file with WordPad, as shown in Figure 1. The Postscript file itself describes the features and parameters of the image to be displayed or printed in the Postscript language. When the Postscript file is displayed or printed, it is interpreted and executed by the Postscript interpreter, and the specific printing or display is performed to obtain the desired image. . Figure 2 shows the Postscript file in Figure 1 in a Postscript file reader. You can see that the Postscript file is interpreted and displayed, resulting in a colored page. Postscript files have many advantages over other formats. The above mentioned device independence is a very important point. Postscript files also have the advantage of being independent of the operating system platform. Because many Unix graphics environments themselves have support for Postscript as part of the core, so whether you are using a Windows* operating system or a Unix* operating system, you can read and print P ostscript files. This makes communication easier. . Because Postscript files are stored in text, the files are small and suitable for transmission over the Internet. There is also a unique advantage in printing and displaying on Postscript devices (printers, monitors) for the best results.
There are several ways to generate Postscript files:
(1) You can refer to Postscript's language format, and write a Postscript file directly with your text editor as needed. Of course, if the file is more complicated, the workload is not small, and you must be familiar with the syntax of Postscript.
(2) You can use special Postscript file editing software or some text, image editing software to provide the function to generate Postscript file;
(3) There is also a simplest way to add a Postscript printer (virtual) to your operating system. Then in the text editor or graphic editor, the image you need is printed via that Postscript printer. In another file, the resulting file is the Postscript file you want!
