Can WORD output film?
A: WORD can also be output directly to the output company (if necessary copy the font to the output company). The general practice is to print to the file *.prn format, and then to *.ps format, this work is generally done by the plate-making company, you just provide WORD file on it. However, you should pay attention to the compatibility of fonts, and whether there are page changes and skipping after the plate-making company is opened, and the size may change. In the past, the coloring of WORD was RGB, and it could not be colored. Current RIPs can generally convert RGB to four-color output.
Is it right to draw a cross with a cross on the four sides of the file?
Answer: Yes. With a very fine line (0.076 mm), CMYK is defined as 100 cmyk each in the normal printing state.
How many mm is the distance between the distance between the well-established version and the paper? Last moderator said to stay 14mm, is not any open number to leave 14mm. If so. Why do we leave 10mm left and right?
A: 1, first of all depends on the print bite, usually 6-10mm.
2. Look at the pros and cons, the left and right wheel, or the wheel of the world. The first two are double mouthpieces, and the second one is double bite (note: the mouthpieces are not printed)
3, the best edge bleeding 2-4mm, see the actual situation of the middle bleeding (see the same color background, color background, knife cutting, die cutting, etc.).
How to set bleeding position in Chinese version of CD 9.0? Where is the cutting line? Is it manually set or something else?
Answer: The crop marks can be selected when the printout is printed. To bleed, the default is 2mm, or it can be manually added to 3mm.
When you right-click on an object in CorelDraw, there are "overprinting," "overprinting," and "covering and coloring." What is their role?
A: These are all to avoid setting up the color error in the printing process. Basically, they all belong to the same type of meaning of trapping. Generally, they can be ignored.
In the production of color prints, where text, line drawings, and images are superimposed on one another, it is often the case that when these objects are superimposed on one another, they have differences in front and rear order, and the ones that lie in front will cover the back of the table. In technology, the front-facing object is called the foreground, and the object behind it is called the background; this front-to-back order is called the layer. If the foreground and the background have different colors, images with the same area and size appear on the respective color separation sheet or are hollowed out. In actual production, it is difficult to achieve very accurate results in the process of making and printing, so that the white or color overlap between objects in the printed matter will often appear, which will affect the final output image.
With the perfection of the desktop technology, applying trapping control (also called trapping) at the overlap of various objects has become an essential function of the desktop system and is solved through software. Trap control technology is the use of computer software to solve the absolute overlap accuracy that is not easily obtained in the actual plate making process.
The general principle of trapping is to use dark colors to define the outlines at the borders where there is no common color, and to create a fine border of common colors at the borders that have common colors.
In color prepress software technology, trapping technology is a cross-product technology, and involves the cooperation of a variety of applications, based on the PS page language
