A: It will help designers prepare output files and export them smoothly.
1. Set the file so that the page size of the layout file matches the page size of the print, and let the application software automatically generate the correct positioned cutting line. Using numbers - Now there are two ways to determine the size and position of page elements in each typesetting software. One method is clicking the perceptual method of dragging the mouse, and the other is an objective method of entering numbers from various dialogs and control panels. To make sure that the exact width of a box is exactly one and one-half inch, the only correct way to do this is to enter 1.5" in the width column instead of using eye or aligning the reference line and size.
2. Unless the font is very complicated or finely detailed, turn any text in the EPS file into a path before you enter it into the layout software. Use good fonts - Many output centers do not want to see TrueType words, PostSript has become a standard. TrueType usually has the same word name as the corresponding PostSript word, causing conflicts. TrueType must be manually downloaded into the RIP of the imagesetter. This is a time-consuming task. Contact the export center in advance. Do not use font commands to create bold or italic effects. It is best to select the desired font effect directly from the application font menu. For example, if the font does not have the desired rough or oblique effect and the font command is used, the MAC will forge a bold or italic effect for each character, but this is only on the screen. If it is output on the printer, the final printing effect looks as if it has not been used at all. So what's the effect of using the underline? Don't use fonts that do not have the effect that the font itself has. If you are using a beautiful serif or fine-brushed font (Bodoni is a good example), and the size of the word is set to be very small, do not separate the words. Otherwise, even slight misalignment of the plates will cause overprinting of the most sensitive parts.
3. Scan or get images as large as possible at the final output size and the appropriate resolution (larger ones are not necessarily good).
4. Rotate, mirror, or invert the image in the software that created the image, rather than in the typesetting software.
5. Remove extra paths and channels before storing the last picture to simplify the file.
6. If the image is to be color-separated, the color is defined using the CMYK mode, and if it is not, it is defined as a spot color.
7. Store pictures in uncompressed TIFF or EPS format.
8. Print test separations on a laser printer to ensure that you don't have extra separations or unwanted spot colors.
9. Use QuarkXPress Collect for Output or Adobe PageMaker's Prepare for Service Bureau widget to ensure that you know which fonts are included and send the fonts along with your files to the output center.
10. Leave traps and layouts to the output center unless you have previously discussed and reached a tacit agreement.
11. When sending documents to the output center, clearly indicate on the disk which file is required, and include a proof sheet marked with a cut and a bleeding mark, preferably printed (100%) in the final output size. Be sure to find out the resolution (number of lines per inch), ink, and paper used for printing. Then set the corresponding number of network cables in the application software. When you have a negative film, you should explain it to the output person, otherwise the output person will give you a positive film as usual.
12. Once you get a copy of the sample from the output center, check to find out what went wrong.
13. Make the gradient smooth
