In　printing　processes,　printing　ink　temperature　and　viscosity　had　a　great　influence　on　the　printing　quality.　Based　on　the　thermal　elastohydrodynamic　lubrication,　the　energy　of　the　ink　layer,　the　thickness　of　the　intermediate　layer　and　the　temperature　of　the　ink　layer　in　the　contact　areas　of　the　two　ink　rollers　were　calculated　by　using　MATLAB.　The　distribution　of　ink　temperature　was　studied　at　different　locations　along　the　contact　zones　between　the　layer　thickness　of　a　soft　and　a　hard　ink　roller.　The　effects　of　loads,　roll　speeds　and　the　ink　materials　on　the　maximum　temperature　of　the　intermediate　layers　were　studied.　The　results　show　that　the　temperature　of　the　intermediate　layer　ink　is　the　highest　at　the　different　positions　along　the　thickness　direction　of　the　intermediate,　and　the　temperature　is　lower　near　the　two　rollers.　With　the　increases　of　the　loads,　the　maximum　temperature　rise　of　the　intermediate　layer　increases.　With　the　increases　of　the　roll　speeds,　the　temperature　of　the　intermediate　layer　of　the　contact　zones　between　the　two　rolls　is　not　changed　greatly.　With　the　increase　of　the　elastic　modulus　of　the　soft　roll,　the　temperature　rise　of　the　intermediate　layer　is　increasing.　©　2018,　China　Mechanical　Engineering　Magazine　Office.　All　right　reserved.
