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 Include halftone 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.

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).
