What are the issues that must be noted before delivering documents to the printing factory?

When printing documents are sent to the printing factory for production, in addition to checking the text rotation, image pixels, and links, the following issues must also be noted:

1. Choose commonly used design and production software during production, such as Word, and try not to use it as much as possible.

2. The mode of the image in the text must be CMYK mode, with a minimum accuracy of 300 * 300dpi/pixel/inch.

3. Check if the text in the publication is in four colors, and if so, change it to monochrome 100% black.

4. If using pagemaker, Weisi, Founder Edition, Illustrator, the linked image file must be copied together with the original file.

5. The photoshop file should preferably be a psd (unmerged layer) file for easy modification.

6. Try to use commonly used fonts such as Fangzheng and Wending. Try not to use rare fonts. If already used, coreldraw and Illustrator first convert the text to an outline format to avoid the problem of not being able to output due to the absence of such a font in the output center. If there are supplementary files, they must be copied together.

7. Clearly inform the finished product size, printing quantity, printing paper, etc. of the printed material for easy assembly and hanging.

8. If the content on two pages is the same, but the black text part is different (often encountered), then simply output the CMYK four colors on the first page and the K color on the second page.
