Before explaining how to make your own electronic signature, let's talk about what the electronic signature is for.

As the name implies, electronic signature is to turn your paper signature into an electronic version, just like logo, which appears where it needs to appear.

Everyone has a diploma. The name on the diploma must be in a uniform font, but the principal's signature must be personalized. If you can't remember the name of the headmaster, you can take it out to remember the lost youth. Similarly, if you have applied for a patent, you will find that the patent certificate also has the personal signature of the director of the patent office. These are all applications of electronic signature.

The above are all electronic signatures made by the big boss for batch documents. What's the use of making your own electronic signature?

When we are in the field, but there are documents to be signed, we can print them out, sign them and mail them; There is a faster way to insert the signature into the signature and send the electronic version to the client for printing, and you're done.

Here are two methods for readers to try. First, write your signature on a blank piece of white paper, and make sure that the signed paper is flat.

The first one is very simple. Put the signature in a well-lit and even place, adjust the mobile phone to the best position and take a photo of the signature.

The second is to use the software similar to Scanning Almighty King to output the handwritten signature as a PDF file by taking photos. The specific operation is the same. Put the signature in a well-lit and even place, set the mobile phone to the best position to take a photo of the signature, and then choose the storage format as PDF.

PS。 If you have a hand-drawn software similar to iPad, you can also write your own signature directly and save it as a picture format or other file formats that are easy to edit. You can try it yourself.

After the signature material is made, you need to use PS tools for some processing, so that you can use logo at will. The operation is simple. If you can use PS, you will probably know how to do it when you see the title, but in line with the concept of mass popularization, the specific operation will still tell you in detail.

1

Open PS, transfer the generated PDF file to the computer, and open it with PS. In the window that appears later, just cut it to the border with option (P).

If it is a picture signature material, use Ctrl+O to directly select Open.

2

Click image rotation (g) in the menu bar image, and then click 90 degrees (counterclockwise) (0) to rotate the image. If the signature in the image is normal, the rotation operation will not be performed.

three

Ctrl+J copies a layer, then click Adjust in the image, click Threshold, and then click OK in the window that appears later.

four

Click the newly created layer, set its mixed layer mode to active overlay, then right-click its layer and click Merge Visible Layers.

five

Ctrl+J copy the layer, turn off the visibility of the original layer (eye icon), click the magic wand tool, click the blank area of the image, create a selection, and press the Delete key to delete all the white backgrounds in the layer except the signature.

If some blank backgrounds cannot be selected, use the magnetic lasso tool to click a circle bit by bit along the edge to form a closed selection, and press Delete to delete it.

six

Click the crop tool to frame the signature.

seven

Press Ctrl+Shift+S, select PNG format in the window that appears, and then save it to your desktop or other file.

PNG format can display transparent background, but JPG can't.

The final effect is shown in the following figure:

At this time, you may wonder why this transparent background is still white. Only by putting pictures on other pictures can we play the role of transparent background. A few examples will be given later. Just to explain, according to the above steps, the color of the signature is black. If you want other colors, you need further processing. If you are interested, you can study it yourself.
