In　this　paper,　the　finite　element　simulation　software　Ansys　Workbench　was　used　to　simulate　the　influence　of　ink　roller　speed　in　the　ink　temperature　field　during　the　printing　process.　Different　ink　roller　speed　the　influence　of　the　temperature　of　the　ink　flow　field,　the　temperature　change　trend　of　the　surface　ink　and　the　extrusion　area　ink　was　analyzed.　And　the　experiment　platform　of　ink　printability　tester　was　used　for　experimental　verification　of　simulation　analysis.　Using　the　infrared　thermal　imager,　the　ink　temperature　field　cloud　picture　of　different　time　and　the　ink　temperature　at　real-time　data　of　extrusion　area　were　obtained　respectively.　Finally　through　the　contrastive　analysis　of　the　experiment　and　simulation,　the　effect　of　ink　roller　speed　on　the　printing　ink　temperature　field　was　obtained.　When　the　pressure　between　the　two　rollers　keeps　constant,　the　ink　roller　speed　has　larger　influence　on　the　ink　temperature　in　steady-state,　without　considering　the　new　ink　inflow　and　high　temperature　ink　outflow,　the　ink　temperature　at　extrusion　area　increases　with　increase　of　the　ink　roller　speed.　©　2015,　Beijing　University　of　Technology.　All　right　reserved.
