The new logo and name was unveiled last week at the charity's 182nd annual lunch at Stationers' Hall, where Trinity Mirror chief executive Sly Bailey was welcomed as a guest speaker.
More than 200 people from the printing, publishing and graphic arts trades filled the Grand Hall – the first time the event had sold out for 12 years.
In her speech, Bailey argued that print is a complementary media to new technologies and said that today's opportunity was to create a multi-media publishing platform across online, print and mobile technology.
Johnson said it was "a great honour" to be invited to be president for a second year. "I'll continue to build on the excellent work being done by everyone at the PCC to achieve its aim of increasing the number of people it helps year-on-year."
