Details are as follows:

1. After opening photoshop, open (CTRL+O) a picture with official seal.

2. After the picture is opened, execute "Select-Color Range". When the "Color Range" window pops up, click red (official seal color) for color sampling.

3. After sampling, click OK. At this time, you will return to the canvas, and you can also see the constituency covered with the official seal on the canvas.

4. Next, just press "CTRL+J" to copy the official seal of the selection, and you will get "layer 1".

5. At this time, you can hide the background layer. After hiding, you will find that the general outline of the stamp has been dug out, but the color is not that color. It doesn't matter. Next, you should adjust the hue saturation of the layer 1

6. Execute "Image-Adjustment-Hue/Saturation" or directly press the key combination "CTRL+U" to open the hue saturation, and then adjust it to make its chromaticity as close as possible. Note that when adjusting the hue saturation, you should check the preview, so that you can see the color of the official seal more intuitively and adjust it better.

7. After adjustment, click "OK". At this time, you will find that the color is still a little light. It doesn't matter. Just copy the layer 1 (CTRL+J). According to your own situation, copy several layers and set the opacity. Together, you can get a perfect official seal.

8. Note that if you want to use this official seal in word and other places, the saved picture format must be PNG.

9. Complete the renderings.

Precautions:

Electronic seal technology is to simulate the traditional physical seal with advanced digital technology, and its management and use methods are in line with the habits and experiences of physical seals. The electronic document stamped with its seal has the same appearance, the same effect and similar usage as the paper document stamped with its physical seal.

Long before the promulgation and implementation of China's Electronic Signature Law, electronic seals appeared. In the middle and late 1990s, as the traditional office mode gradually changed to the information office mode, the circulation form of paper documents also changed to electronic documents. In order to ensure the validity of electronic documents and make them have the same visual effect of public trust as traditional paper documents, the concept of electronic seal is put forward.
