What is the output distribution?
The output is based on RIP technology. That is, a raster image processor, which can convert graphics, images, and text information into a variety of large-format printers or pages of the language of the machine to understand the ability to complete the output. It can control the printing accuracy, color and format size.
No matter what kind of RIP, there are two kinds of technologies for converting electronic documents into print languages: First, color separation; second, screening. Separation is generally four-color, and sometimes there are more spot colors. RIP is divided into hardware and software. The hardware RIP is built into the printer imagesetter or a dedicated hardware RIP chassis; the software RIP includes the software body and various device drivers. The software body is rasterized, and the formed image file is sent to a corresponding external device for output by a specific device driver. Hardware RIP is generally not flexible enough. The issuing machine can only dispatch, it can not be used, and once the host has a problem, it is not good to repair; while the software RIP is flexible, the issuing machine can be used. When the host computer has a problem, you can reinstall the RIP software by changing the host. So software RIP is more convenient to use.
Commonly used software There are two types of RIP on the market. One is the PSPNT RIP series from Peking University; the other is Harlequin's Express RIP series. Founder's PSPNT RIP is very convenient when printing Fenton or wits-generated PS files. Special PS file generation, very fast. As long as you take the picture path while printing, you can print successfully. But the dots it generates are sometimes false, not real enough; printing is very troublesome when generating PS files on a Mac. Sometimes it is impossible to print at all. In the lower version, color preview is not available for files printed on Mac. Until the latest Founder Century RIP was launched, this problem was solved. But when previewing dot-matrix information, it cannot be stored. The Harlequin Express RIP generates outlets that are relatively solid and clear. Whether it is a Mac or a PC, the layout files on it can be printed out in a row, and can be printed directly, without the need to generate an intermediate point in the PS file. Of course, it cannot print wits or fly-through generated PS files.
Introduction Output Difficulties:
1 Problems with black prints After black prints were blacked out, the black text did not directly press against the background, and white text appeared around the text strokes. Because the text is reflected on each color plate, plus the change in the temperature of the printing shop, the paper will expand and contract, making overprinting inaccurate and affecting the printing effect. In order to avoid this phenomenon, when publishing, you should choose not to empty or black imprint in the corresponding options.
The consequence of converting the 2RGB mode to the CMYK mode is that there are only grayscale maps on the color separation sheet that have the equivalent of the map or the 4 color versions, rather than the desired color map. So be sure to check before posting that the image in the layout is in CMYK mode. In addition, we must also pay attention to, in Photoshop in the map processing, and merge the layers, be sure to delete the channel. Otherwise, image information will be missing when publishing.
3 Bold Font Problems This problem appears in Freehand and Pagemaker. If Freehand's Chinese font uses heavy, most cases will produce a paste word when a film is produced; while in PM Chinese uses bold, it must be a toothed overlap word. There are also problems with other font effects in PM. To avoid the above problems, the first step is to use the text in the corresponding bold text. For example, choose bold song or big black. If there is no corresponding bold typeface, you can use fill and stroke in Freehand. However, there is an experience that the size of the word can not exceed 3% of the original size. If the font itself is thick, the proportion is even smaller.
4 If there is a gray net when overprinting, if there is a gray net during overprinting, objects under the gray net will pass through. Others should also note that overprinting is specified in the file because the current version of the software does not see which objects were overprinted. The solution to this problem is to add 1% yellow when defining grey.
The consequence of the misuse of the 5JPEG compression format is that there is an image on the screen and the output is missing. The solution is to save it back to TIFF or EPS format in Photoshop.
Scaling Problems in Figure 6 Now that the layout software zoom map is convenient, the cost is multiple output times. Therefore, be sure to set the size and resolution in the image processing software and then put it into the layout software.
7 Wrong use of DCS format This will produce three different consequences. First, there are plans for black and white printouts, but there are no plans for the output of the film; second, when the color is printed, the color image is changed to a black and white image. Third, although the print is a color image, it is very rough. The reason for the occurrence of phenomenon 1 is that there is only the main document at the time of output, but there is no separation document; secondly, the main document only contains the grayscale image of the low solution force; and the main document only contains the color image of the low solution force. Therefore, do not use the DCS format unless you have a particularly good reason or have a particularly good understanding of DCS.
8 Misuse of the EPS with the network is the result of a network cable output, the number of pictures on the film is wrong. The reason for this problem is that when the image is stored in the EPS format, the screening information is selected. Therefore don't feel free to move this option when saving EPS. Of course, the EPS band network function can achieve some special effects, such as line network effect or intentionally using different network lines in the same plane to achieve a special purpose.
9 Wrong use of "pattern" pattern filling tool Freehand has a pattern filling function that can fill a regular pattern within a pattern. Such patterns are dot-matrix. Earlier equipped level I RIP imagesetters do not support this filled output, and level II imagers can output. But one thing to note is that you can't set a color other than the field. If you try to set a color of M30% and Y30%, although they are all displayed on the screen, the output must be 100% large red for M and Y.
10 Problems with fonts Sometimes fonts are missing on the machine, resulting in fewer characters on the film. This requires the preparation of the design and production first, turning the text into a curve or path. If the text has special effects, it should be effected before it is turned into a curve or path. When inputting words, please also pay attention to using GB input method and Chinese characters in GB inner code. The numbers and English characters are in English. When the software has text left-right alignment, try not to use spaces to move words. If you must use spaces, use English spaces. Be careful with punctuation. Chinese simplified punctuation is below the character. Traditional Chinese punctuation is in the middle of the character.
