Create a transparent Watermark

using the free GIMP (GNU Image Manipulation Program)

This tutorial requires that you have installed GIMP for Windows and  Arclab Watermark Studio on your computer. We use GIMP version 2.6 and Watermark Studio [an error occurred while processing this directive]in this tutorial. Future version might look a bit different, but the basics should be the same.

Its also possible to make an existing image transparent using Arclab  Watermark Studio (click on "Make Transparent"), but the edges might look a bit outlined, depending on the image which should be used as watermark. The problem might be the gradient from the foreground to the background. You will get the best results when using an image with a transparent background (alpha-layer).


1. Create a new image in GIMP

2. Add some Text, Drawing or Logo

We use a simple text with a drop-shadow for this sample.

Its important that you see the squares, which means it has a transparent background. This also illustrates why its the best solution to use a 32bit transparent image. If the image would have a fixed, e.g. white background then the shadow would be on a white background, which means the shadow (and also the edges of the text) would be outlined on a different background color.


3. Save the Image as PNG

4. Save Options - Merge Visible Layers

Now the "Export File" dialog opens. Our image contains multiple layers, but a PNG cannot contain multiple layers, so we have to select what should happen with the layers. If your image does not have multiple layers, then this dialog won't open and you can skip the following.


5. Run Arclab Watermark Studio

run watermark studio

Now you should see the transpart image in "Watermark". I have changed the "Watermark-Size %" to 100, so that you can see the shadow of the transparent image. If we wouldn't have saved the image as transparent PNG, then the shadow would be outlined.

Now we are done.
