Wozencroft founded Touch, an independent multimedia publishing company. Between 1982 and 1986 Touch "released around 15 products, concentrating on producing interactive, audiovisual magazines such as Feature Mist and Touch Travel, both of which sold over 5000 copies without any advertising (which we could not afford)."  Touch is still active today.
In 1988 Wozencroft's book on his colleague Neville Brody was published as The Graphic Language of Neville Brody. Wozencroft and Brody went on to found and publish FUSE – an experimental publication of graphics and experimental fonts.
According to his biography, Wozencroft has had extensive experience teaching design. He has been a lecturer at Central St Martins College of Art & Design and at the Royal College of Art, both in London. According to his RCA biography, "In 1994 he was appointed main tutor and assistant course director for MA Interactive Multimedia at the Royal College of Art. He is currently Senior Tutor in the Communication Art and Design Department at the Royal College of Art."
