A droplet deposition apparatus () comprising: a first head module (A,B,A) and a second head module (B,A,B) arranged in at least partially overlapping relationship, each head module having a plurality of nozzles in at least one nozzle array (A, B); and a storage () configured to store a table of determined best aligned nozzle pairs in an overlap region and corresponding skew angles (Θi) of at least one of the head modules relative to a datum of the droplet deposition apparatus and/or a corresponding positional offset of the second head module relative to the first head module; wherein, in the overlap region, nozzles of the first head module are arranged at a first nozzle pitch (P) and nozzles of the second head module are arranged at a second nozzle itch (P). Associated methods in respect of determining misalignment information in respect of such a droplet deposition apparatus, and determining one or more best aligned nozzle pairs in an overlap region between at least two head modules, are also provided.
