At the heart of an academic publishing house lies the journals. At MDPI, each journal is run like a small independent company, and they all have a set of graphical assets created for them from their genesis. Central to that set is the journal logo: bound by a strict set of rules designed to keep family resemblance between de 480+ journals, this small square illustration will represent the essence of the journal and function as its face in all the platforms and formats needed. I was in charge of developing and maintaining this massive library of assets for various years, which is both a big technical challenge and hundreds of mini creative challenges.
