Reverse print is not hard to set up for most projects. You simply tell us that you need it and usually we can set it up using your main art. If you need something unique for the reverse print, send it or tell us the color if it's just a flood you're adding.
Leo needed some elements to span two panels, while the Leo on the pencil loop needed to only appear there, and not be repeated on the spine.
Note how on the PIPS art, below, there's a narrow strip of ink around the outer edges, as well as between the spines. We do that edge printing with PIPS so that when you view the inner panels on the final assembled piece (which are usually cut slightly smaller than the outer panel), any thin reveal of the reverse side of the stock will match the main art.

The result is complete coverage, and a very high-end look.
