请问一个英语语法表达问题?
This paper proposes a PDF document watermark embedding method, for the PDF text watermark method which has low watermark capacity and poor robustness and so on. It will make PDF document into image files, and then add watermark information in it. According to the experiment, the method improves the capacity of the watermark, so the intact copyright information can be embedded in the PDF document. And the document storage and reading will not be affected.
