Prepress output problem solution (below)

Before printing, you must pay attention to the following issues:

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.
4. If pagemaker, WS, Founder, and Illustrator are used, the linked image file must be copied along with the original file.
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.

Network point of view Green: 15 degrees Red: 75 degrees Yellow: 90 degrees Black: 45 degrees The arrangement of the general network is neat, so there will be points of application in the point of view, such as monochrome printing, the cable angle is mostly used 45 degrees, this is based on the dots printed on this point, for the visually most comfortable and difficult to detect the presence of outlets, resulting in continuous gray tone effect. 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.

Prepress production output experience (let you get out of the prepress production predicament)
The font used in the file, confirm the output center, or need to carry.
When storing graphics, check whether the color mode is CMYK mode to avoid color deviation.
Check the link file before output, and change the link information in time if there is any change.
Images with a large amount of graphics are stored in the EPS format, and the Includehalftone and Include... options are not included in the storage options. If they are placed in PageMaker, they should be cropped and rotated before being placed.
If the graphic is in TIFF format, delete unnecessary channels and paths before storage. It is recommended not to save the LZW compression format.
The TIFF format with a large amount of graphics is placed in the PAGEMAKER layout file, which is prone to tensile deformation and should be stored in EPS or DCS format.
PC version Pageaker 6.5C Chinese font download, easy to lose words, symbols take place, big characters with teeth.
Inserting EPS file in PageMaker is easy to lose after rotation. Please rotate and insert PageMaker software.
Don't use bold and underline effects for Chinese characters in PageMaker.
When entering text into the PC, PageMaker should delete the space, otherwise it will be garbled.
There is a problem with the version of the PC font library. After the substitution, it is easy to produce text moves and loses. Please indicate the output center, the font version number used.
PageMaker's trapping options need to be used with caution. Please see the preview effect.
Fonts in CoreIDraw 8.0 cannot use Chinese fonts in the Windows system such as Arial, Bold, and Carcass, and do not print file information when printing.
Forty-four versions of the Chinese text of the four treasures of Chinese scholars will be output. Words will appear before the words.
CORELDRA's PSD format image output is very slow, in some versions with channel or rotation will cause image defects, should be converted to a bitmap.
Do not use paragraph text in CORELDRAW. Please change to art text or to a curve.
In CORELDRAW, you can use the shading and pattern provided with the software to fill in the graphics, or as a base map; use Note:
1, choose the appropriate precision, usually 1.5-2.0 times the number of output lines, if the accuracy is too low will affect the accuracy of the map, too high will affect the output speed.
2. The selected basemap should pay attention to whether its attribute is CMYK mode. Generally, the basemap shading filled is RGB mode, which should be changed to four-color mode.
When using CORELDRAW version, in order to improve the speed (output) if the file is relatively large, the version of the graphics is more, it is best to combine several small version of the bottom map into one, reduce the amount of information in the file, increase the output speed, Note that text should not be converted to bitmaps (especially small words). If characters are converted to bitmaps, the accuracy of the text will be affected.

ILLUSTRATOR, FREEHAND, white fills and lines, check the OVERPRINT option in the property to avoid loss.
Spot color gradients in the ILLUSTRATOR file should be noted during color separation interpretation. Please prompt the output center.
If using EPS DCS 1.0 2.0 format or PS IMAGE format, please prompt the output center.
Gradient processing does not work well in desktop systems. It is best to add 3-4 noise points to PHOTOSHOP's filters during production.
Please pay attention to the following when using the Founder WITS typesetting software: There are several fonts in the WITS's own font that cannot be distributed in the output center: Coarse Song Amber 2 Extra thick Black Zhongyuan Caiyun Han Jian Song Sixin Newspaper Song Ping Black Skinny Gold Yellow Grass length 牟 牟 Japanese 1 Japanese 2 Japanese 康 康 康 When exporting, please indicate whether the output center has a large area of ​​darker colors (red, yellow, black).

Such as using CoreIDraw, Freehand, ILLUSTRATOR and other vector graphics editing software, fonts, such as no special effects processing, it is recommended to turn into a curve or path, this can guarantee the foolproof font.
