Multinozzle　printing　processing　with　the　fabrication　of　a　functional　material　film　lays　the　foundation　for　the　development　of　efficient　scale　production　of　a　photoelectric　device.　However,　a　prominent　challenge　is　how　to　realize　the　volume　uniformity　of　the　droplets.　Here,　a　classical　analysis　method　is　introduced　first　by　printing　poly(3,4-ethylenedioxythiophene)/poly(styrenesulfonate)　(PEDOT:PSS)　to　analyze　the　behavior　of　droplets.　It　relies　on　a　variance　calculation　for　the　clarification　of　the　law　of　implicit　behavior　of　droplets　in　terms　of　digitizing.　This　method　reveals　the　effect　of　printing　parameters　on　the　uniformity　of　the　volume　of　droplets　in　multinozzle　printing.　Overall,　by　combining　both　ink　formulations　and　printing　parameter　optimization,　it　is　concluded　that　the　minimum　volume　variance　of　nozzles　with　different　numbers　is　less　than　0.5%　and　the　influence　of　various　parameters　in　multinozzle　printing　is　found　to　be　ranked.　The　feasibility　of　this　analysis　method　is　presented　and　is　of　great　significance　to　achieving　a　very　stable,　large-scale　multinozzle　printing　device.
