2, make the gradient smooth-using QuarkXPress and Illustrator to calculate the gradient, the effect is very good in a short distance of a few inches, but if you try to make a small gradient on the whole page, the limitation of PostSript may lead to a ribbon effect. Make the gradient into a raster image in Photoshop (add noise by using), and then import it into other applications. However, you can't use Photoshop to work with layers made in Illustrator. Compared with the gradient generated directly in Photoshop palette, the Illustrator file processed by Photoshop cannot generate an ideal intermediate gradient.
3. Use fonts well-many output centers don't want to see TrueType words, and PostSript has become the standard. TrueType usually has the same name as the corresponding PostSript word, which will cause conflicts. TrueType must be manually downloaded to RIP of imagesetter, which is time-consuming. Please contact the output center in advance. Do not use font commands to produce bold or italic effects. You'd better choose the desired font effect directly from the font menu of the application software. If the font doesn't have the desired thick or oblique effect, using the font command, the MAC will forge a bold or italic effect for each word, but this is only on the screen. If you print it on a printer, the final print will look like it has never been used at all. So, what's the effect of using underscores? Don't use fonts that don't have their own effects, use fonts with font commands. If the font you use has beautiful serif or fine strokes (Bodoni is a good example) and the size of the words is set to be small, don't separate the words. Otherwise, even if the printing plate is slightly misaligned, it will cause misregister of the most sensitive part.
4. Color conversion-Before sending the file to the output, the RGB color should be converted to CMYK. Of course, RGB colors look good on the screen, and many professionals prefer to use RGB mode, but do you know? What will these RGB images look like after color separation or printing (many typesetting software could not even separate RGB images in the past). Convert the image to CMYK format (in Photoshop or other software that can do this conversion) before putting it into typesetting software or sending it to the output center. Make sure that spot colors are not designated as spot colors, or on the contrary, spot colors are designated as spot colors. Such a mistake may ruin a movie. If your time is precious, paying for a movie yourself is definitely not what you want. Make sure that the color you define in the typesetting software has the same name as the color used in the image processing software. Otherwise, the typesetting software will treat the separations defined in Illustrator and FreeHand as spot colors. Now, QuarkXPress and PageMaker can recognize this color and add the color name contained in any EPS file placed in it to the color list. Therefore, this danger is not too great, but I want to mention it to you here.
5. Use numbers-Now every typesetting software provides two methods to determine the size and position of page elements. One is the perceptual method of clicking and dragging the mouse, and the other is the objective method of inputting numbers from various dialog boxes and control panels. The only correct way to ensure that the width of a box is exactly one and a half inches is to enter 1.5 "in the width column, instead of using the purpose or aligning the reference lines and dimensions.
6. Set the typesetting page to the actual size-in the unsatisfactory days before, prepress workstations and imagesetters could not record bleeding beyond the page range. If you want to get the correct bleeding, you must change the page size in typesetting software to adjust the actual page size and bleeding. This must have a large page size, so that the cutting line can be drawn and placed by hand, which is easy to make mistakes. Today's prepress equipment is no longer hindered by these restrictions (today's imagesetters can record larger formats and use wider films). Most printing devices suggest setting the file size to the actual size of the page, so that the application software can automatically generate correctly positioned cutting lines.
7. organize documents-talking about this may be redundant for veterans, but it has to be strengthened for novices. In addition to taking away all the image files used in the file, we should also take the dot matrix characters (screen display) and outline characters (printer use) used in the file to the output center. At present, most typesetting software collects and outputs documents similar to QuarkXPress, which can get detailed reports of documents and automatically copy documents to folders, floppy disks or SyQuest disks. If the output center is configured higher, they will definitely have Adobe fonts, so you don't need to bring words.
8. Check the documents-did you hear what you can and can't do in steps 4 and 7? Actually, it's a very simple check. The inspection should include: checking every missing page element, colors that are not correctly defined and PostSript errors. Check tools are as simple as Document Doctor for QuarkXPress of Lepton Technology or CheckList for PageMaker of Adobe, and as complex as systems such as LaserCheck of Mei Lite or Download Mechanical of Acquired Knowledge. Panther Proof or Adobe Preview Pro can perform a screen preview of low-resolution output, so that you can check and solve common PostScript errors before output. "Huayan Proofing" software has the powerful function of finally checking whether the document is wrong.
9. When printing the proofing output file, please indicate the color separation. If you can't find a color printer around, the color labeling method used in the past is very useful. You also need to enlarge each color separation, which is very useful for hollowing out overprint!
10, call the output center-not at the end of the workflow-but at the beginning. Many output problems can be avoided by finally contacting the person in charge of output. Don't think that good-looking files on the MAC screen must meet the requirements of the output center, just as good as printed ones. Be sure to know the resolution (lines per inch), ink and paper used for printing. Then set the corresponding number of network cables in the application software. When making negative film, you should explain it to the output staff, otherwise the output staff will give you positive film as usual. Time is precious to every publisher. Did the 10 tips of the above printing experts save you some time? I hope the introduction of 10 above can bring you some enlightenment, and the original output is not terrible.
The transparency effect in vector software should be combined with the base map, otherwise fine white lines will appear in proofing, because Postscrip3 3 does not support transparency now, so the transparency you do will be converted into blocks of pictures.
Do not use font effects (Chinese characters) in Pagemaker.
It is best not to rotate the EPS diagram in Pagemaker.
If the black text must be stamped, otherwise it may be inaccurate. If you do spot color, you'd better print it twice and make a size version.
Text smaller than 16 point (350dpi) cannot be entered in Photoshop.
In vector software such as Illustrator, Freehand and Corldarw, the printing resolution should be set above 800dpi.
It's best to mix at most three printing colors so that the colors won't be dirty. It is best to add 50% blue to the full version of black, and don't use the default black in Photoshop. Four-color black is easy to print gray.
Description: EPS is a file format, which can be used across platforms without damage. You can keep the format of the original software and import it into another software for editing.
Postscript is a printing font standard, which is simply a relatively clear vector font standard.
Fourth, prepress
1. White exposure/white leakage: the printing paper is mostly white. When printing or plate making, the color of the connection is not dense, revealing the background color of white paper.
2. Whitening: the photographic plate-making process in the net-hanging era. In order to remedy the lack of sensitivity of the dark part of the online picture, we can remove the original picture and flash it once, or put a piece of paper for exposure, or flash white light directly with a flash to increase the depth of the original picture and make the image soft.
3. Burst fat: Overeating will certainly make you fat. If you feel lighter, the film will expand its territory. Manual overprinting is also exposure and fertilization in photosensitive film and transparent thick film.
4. Color trapping: In color separation and plate making, the color intersection is intentionally expanded to reduce the influence of misregister.
5. Field: refers to the area of a color block without dots, usually the full version.
6. Anti-white: Do you use negative lines for words or lines? Printing exposes white paper.
7. Screen collision: In the process of color separation of AM screen, when the dot angle distribution is wrong or the distance between screen angles is less than 25, moire fringe becomes obvious.
8. Flying net: the screen hanging process of lens plate making. After normal exposure, remove the screen, supplement the short exposure and increase the contrast.
9. Dog teeth: Dogs have uneven teeth. There are not enough pixels in the picture, and the edge appears dog-tooth shape after enlargement.
10. Rose spot: a network pattern like a deer. The bad one is called mat pattern, and the worse one is called turtle pattern.
1 1.Flushing: the instruction of layout sorting, with prefix as the baseline. Extended to imposition binding, based on the position of the head.
12. Loose tail: a way of typesetting. Only the word spacing is consistent, not the end of the line is neat.
13. Mask: It is a manual color separation mask. It can be used for film drying or red film cutting, and can be used for film rejection or color correction.
14. Blue version: not B (blue) of RGB, but C (cyan) version of CMYK.

Matters needing attention in movie output
1. file format At present, most of the output centers use the square grid point color separation output system (pspnt), and some of them use Halikun or Israel Saiangel system. But they all have one thing in common, supporting postscrit printer description files. That is, files with suffixes. ps。 At present, popular design software: photoshop, pagemaker, coreldraw.
