If some Chinese characters in the printed document do not have a corresponding font library, the similar library can be replaced in the back end process. At present, there are corresponding setup options for common flow and Indo Chem processes. Operators can set up appropriate font stores to replace corresponding tables based on experience, replace the fonts that are used frequently or have similar styles, and strengthen inspection in the printing process.
