Choose Edit > Identity Plate Setup (Windows) or Lightroom > Identity Plate Setup (Mac OS).
In the Slideshow or Print module, click the Identity Plate preview in the Overlays panel and choose
Use a Graphical identity plate, it uses a graphic that is usually no more than 60 pixels high that you drag into the box.
The graphic should be a PNG file.
Choose Save As from the Enable Identity Plate menu, and give your Transparent PNG Item a name.
To display your Transparent PNG Item, select Enable Identity Plate and choose one of your saved Transparent PNG Items from the menu to the right.
TPI’s can be used in Slideshows and on printed output.
The TPI PNG file must be the same ratio (typically 2x3 or 3x2) as the image file that you want to use it with, you can adjust the original image placement, but it is easier if the TPI ratio matches the original image. 1000px x 667px is OK.
The Module picker will only display a small portion of the TPI.
Landscape and portrait orientated images may be used, you can scale and rotate the TPI by using the Lightroom interface.
If you are going to use the TPI’s when printing, 300dpi is a better resolution than 72dpi.
If you are only going to use TPI’s in the print module you do not have to save using the Identity template editor. It is possible to “locate file” in the overlays panel.
If you turn on “zoom to fill frame” you always fill the available space. Doing so will also allow you to pull the margins in closer to the image.
