This　paper　analyzes　the　defect　of　some　methods　for　controlling　the　ink　key　of　offset　printing　machine,　and　presents　the　advantage　of　adaptive　fuzzy　control.　Aiming　at　the　problem　that　the　processing　curve　of　offset　printing　is　changed　by　the　environmental　impact　of　production,　this　paper　analyzes　this　non-real-time　measurement　and　control　system　with　time　delay　and　less　test　data,　and　proposes　the　method　of　adaptive　fuzzy　control　to　amend　the　control　table　and　adjust　the　slope　of　the　control　curve　according　to　the　detection　deviations.　Finally,　the　control　rules　are　adjusted　to　meet　the　actual　situation.　By　simulating　the　control　arithmetic　with　the　example　of　the　control　of　printing　ink　keys　under　specific　conditions　using　Matlab/Simulink,　it　is　proved　to　be　effective　to　achieve　the　expectative　effect.
