In　order　to　improve　the　printing　quality　and　know　the　process　of　ink　transferring　well,　ink　flowing　among　ink　rollers　is　simulated　by　using　CFX.　Firstly　ink　transferring　characteristics　between　two　rollers　are　analyzed.　An　experiment　is　carried　out　to　test　the　accuracy　of　this　simulation　analysis.　Then　ink　transferring　characteristics　among　three　and　five　rollers　are　analyzed　respectively.　The　general　characteristics　of　ink　transferring　among　rollers　are　got　by　comparing　the　velocity　of　ink　flowing,　ink　pressure　and　ink　transfer　ratio　from　those　simulations.　What　is　more,　the　accuracy　of　the　simulation　analysis　is　verified　by　experiment.　And　this　research　provides　a　reference　to　general　characteristics　of　ink　transferring　in　the　actual　printing　process,　and　it＇s　important　for　the　printing　color　quality　control　and　has　a　better　application　prospect.　©　(2014)　Trans　Tech　Publications,　Switzerland.
