Inside-Cover Debossing files must be: 5"x1", 5"x2", or 5"x4"; solid black color; transparent background .png files. Simple designs deboss much better.
Start on your Kiss Dashboard and navigate to Edit Design Profile.
Then, navigate to Inside-Cover Debossing. Select your size and click Choose File.
Once the file has uploaded, navigate to Position to select where you'd like your logo to be placed.
Note: Placement will be the same on the front and back inside-cover unless otherwise noted. You can enable front, back, or both inside-cover logos in the designer.
Add it to your design by opening the Designer and toggling Inside-Cover Debossing on.
Don't forget to select on/off for Back Inside-Cover debossing too! Quickly navigate between front and back inside-covers by using the link at the bottom of the panel.
