Ask the master to give a detailed tutorial of PS handwritten signature.

Using ps software to sketch handwritten signature is as follows:

1, open the PS software on the computer, and open the handwritten signature picture material in PS.

2. Cut off the signature part completely with a cutting tool.

3. Use the shortcut key Ctrl+Alt+I to call up the image size dialog box, and adjust the resolution to 300 pixels and the width to 10 cm.

4. Click OK to execute the command Image-Mode-Gray. Use Ctrl+L to call up the color scale command to adjust it so that the background of the signature becomes white.

5. Click OK, double-click the background layer, unlock it to get layer 0, then execute the select all command, and then edit-cut.

6. Then use Ctrl+Shift+N to create a new layer of 1, and execute edit-paste.

7. Then execute the command of selecting color range for layer 1, and use the mouse to select white as the sampling color.

8. Click OK, then click Delete to delete the white background, and use Ctrl+D to cancel the selection, and you will get the handwritten signature that has been deducted.
