Is the document signed by electronic seal valid after color printing?
The electronic signature can have legal effect because there is a hash value on the file, which can solidify the original electronic file data. Once the document is tampered with, it will be found, so the authenticity of the document can be proved.

However, after the electronic official seal is printed, it is impossible to judge whether the content of the document has been changed by the hash value, which naturally cannot be regarded as a reliable electronic signature. In addition, because electronic signature needs third-party authentication, electronic official seal as a form of electronic signature is no exception. If the electronic official seal is printed, then the third-party authentication cannot be realized, so its legal effect cannot be guaranteed.
