水印

这里说的是页面上重复出现的浅色文字或浅色图案，例如斜着铺开的「样本」「草稿」。体验页里的功能名是「AI去水印」。

什么可以试，什么不要指望

浅色、重复、没有盖死正文的水印，可以试。深色防伪底纹、证件上的安全线，以及你无权去掉的授权标记，不要指望能去掉，也不应去掉。去掉水印不会改变这份文件的权利。

在体验页怎么试

在去污体验里选「AI去水印」后运行。看水印是否变淡，以及和水印重叠的字是否缺笔。水印和正文一样黑时，功能多半分不开，结果会伤字，这时保留原图。

和印章的区别

一块实心红章用去印章。满页重复的浅字用本篇。两者叠在一起时分开跑，每一步都留下上一张图，以便退回。使用条款禁止把去掉标记后的图当成原件。

Watermarks

This guide is about light text or a light pattern repeated on the page, such as a diagonal "sample" or "draft". The tool on the demo is named Watermark.

What is worth trying

A light, repeated watermark that does not cover the text solidly is worth a try. Dark security patterns, a security line on an identity document, and an authorization mark you are not allowed to remove should be left alone. Removing a watermark does not change who has rights in the file.

How to try it

On the cleanup demo, select Watermark and run. See whether the watermark faded and whether letters that overlapped it lost strokes. If the watermark is as dark as the text, the tool usually cannot separate them and will damage the text. Keep the original.

How this differs from a seal

A solid red seal uses remove seal. Repeated light text uses this guide. If both are present, run them separately and keep the previous image so you can go back. The terms prohibit presenting a file with marks removed as the original.
