You really need to sign your name. You'd better write it with a marker to make the lines of your name more obvious.

sign

Take your signature with a camera and try to avoid lens distortion (try to take it with a telephoto lens).

3. Use Photoshop for pretreatment.

Contrast with Photoshop to make the black signature stand out.

4. Separate the black signature from the white background.

Click on the white background with the magic wand tool. If there is a blank space in your signature text (such as the white position in the middle of the word "o"), you can hold down shift and click.

5. Reverse signature

Press Select & gt to reverse the selection, which will become the black signature part of the selection. Click and press Ctrl+C to copy the signature.

6. It's over. Stick your signature file on the work.
