Creating and applying ‘intelligent’ watermarks to batch images
In this tutorial I will explain a method to batch watermark a series of images using Photoshop and Imageready. The watermark will automatically be made on a layer whose blending mode is set to exclusion, which will enable the water-mark to adjust itself so that it becomes visible on white as well as black backgrounds. We could have the whole thing done in Photoshop actually, but for the fact that we are finicky about the exact watermark position and that our source images may be of different sizes, we will take the help of Imageready too.
What you will create in this tutorial is a small application (otherwise called ‘droplet’) with Photoshop’s powerful automation features. Once you save the droplet, you will be able to apply watermarks to any number of images by simply selecting them and dragging them onto the droplet icon. Your source images maybe of different sizes, but the watermark will always be applied to the exact position you specify. Here is how you do it…
First up, we will create the water-mark. Create a new document in Photoshop with following settings:
Choose the foreground colour as black and using the Paint Bucket Tool, fill the background with black. There is a reason why we want the background to be black. (It is because we need to create our watermark in white in order to make them behave correctly when we apply the exclusion blending mode later on.) Grab the Horizontal Type tool and with the foreground colour as white, type the text you want to use for the watermark.
Turn off the visibility of your background layer in the layer palette so that only your watermark is visible on the canvas.
Now let’s save the watermark. Choose File>Save As… from the menu and save it as ‘watermark.png’. (As you are selecting the .png option from the file type drop down, when you click on the save button a pop up will ask whether to save as interlaced or non interlaced. Choose ‘None’ and click OK.
