2. On the basis of the finished product size, add 3MM bleeding position on each side (for example, the finished product 2 10*285, the page of 2 16*29 1 should be made).
3. Pay attention to CMYK mode, and the resolution should be at least 300DPI, which is set at the beginning of the file. If the setting is small at the beginning and the resolution is forcibly changed before leaving the forest, the accuracy of the picture will not be higher.
