Cropmarks is a Photoshop script/action for adding cropmarks to photos. By default, 3mm cropmarks are used but you can change it by replacing a constant in the beginning of the script. The script extends your photo by creating a mirror image of the outermost 3mm, after which it adds 3mm of white border and adds the crop marks so that, when properly cut, only the original photo remains.You can download and use Cropmarks, free of charge!
Download and installing
To download Cropmarks, simply click on the download button. This will download a file install-cropmark.jsx.
To install Cropmarks, double-click on install-cropmark.jsx. This should launch Photoshop and ask if you want to install an action for Cropmarks in the actions panel. (If you don't see the Action palette, you will find it under Window > Actions.)
If double-clicking doesn't work, you can also install Cropmarks by doing File > Scripts > Browse... and choosing install-cropmark.jsx.
If you need to add cropmarks to one photo, just open it and click on the "Cropmarks" action. If you need to apply cropmarks to many photos, I would recommend selecting the photos in Bridge and then doing Tools > Photoshop > Image processor with the settings shown below. Copies of your photos with cropmarks will be saved in a subfolder "JPEG".
