Des Moines Allied Printing Trades Council.

In 1911 the international unions in the printing trades formed the International Allied Printing Trades Association. This group identified union printing with the registered union trademark (the union bug) and encouraged cooperation among its members. The IAPTA also worked to establish local printing trades councils. The Des Moines Allied Printing Trades Council (DMAPTC) was well established by 1935, but over the years the number of printing union locals belonging to the Council varied. Until the late 1970s the Council left matters of wages, strikes, and membership to its constituent members, but the impact of automation and aging membership had weakened the individual print unions in Des Moines. In January 1978 the six printing trades unions at the Des Moines Register and Tribune Company reorganized the Des Moines Allied Printing Trades Council to coordinate collective bargaining and organizing. The Council members at that time were: SEIU Local 103, GAIU Local 584, IPGCU Pressmens' Local 11 and Paperhandlers' Local 8, International Mailers Union Local 58, and ITU Local 118. By the late 1990s the DMAPTC included pressmen, mailers, lithographers, and typographers organized as GCIU Pressmens' Local 11 and Lithographers' Local 157-M, IBT Mailers' Local 58, and CWA Local 14715 (formerly ITU Local 118).
