We're working on a book design, a fairly complex book with details to attend to, many illustrations to place, and some expectation, due to the subject matter, that the result be attractive rather than merely utilitarian. If we can handle all the details, we will have accomplished one thing, but shaping the book into an attractive set of patterns will take us to another level. Beyond mere accuracy we can try for a sense of design.
Do the two pages we see as a spread on the InDesign screen feel as though they were designed rather than just assembled? And does the design for this spread blend well with the designs of the other spreads? Does the book's design cohere? And before we get carried away with making a pretty package, are the details all in place? Does the design serve the subject matter and its many details? We'll see. But that's what we are reaching for.
