  • $\begingroup$ Alpha channel is an extra channel in some image formats to store transparency,you can add an alpha channel is photoshop or any other photo editing software then use it in blender. $\endgroup$

    $\begingroup$ You will just use the alpha output as a factor between your shaders and a transparent shader. $\endgroup$

Solution 1

If your image has alpha channel or you can create it¹, you can use it to mix your original shader with a transparent shader.

Your node setup adjusted:

First solution

¹Since you mentioned psd, I assume you use PhotoShop. Use the magic wand or (polygonal) lasso selector tool to: Select and delete what should be transparent; or add a mask and fill those parts of the mask with black. You may have to setup the image to enable the alpha channel.

Solution 2

If your image has black background, and is only black where the logo should be transparent, you can use that as a condition for mixing your original shader with a transparent shader.

Your node setup adjusted:

enter image description here

You may use other values (between 0 and 1) in the Greater than node as the threshold for masking the darkest parts of the image. Also, you may use Less then node insted to mask white areas of the image (in case your background is white).
