Inkjet　printing　technique　is　susceptible　to　form　coffer-ring　patterns　and　inhomogeneous　films　owing　to　the　evaporation　and　its　accompanying　hydrodynamics　of　microscale　quantum　dot　droplet.　Pioneer　efforts　are　usually　confined　to　two-dimensional　flat　substrates　and　inks　with　mixed　solvents/additives.　Herein　we　demonstrate　that　physically　confined　space　offers　an　additional　parameter　in　tailoring　such　processes　of　droplets　and　the　following　quantum-dot　self-assembly　deposition,　without　extra　modification　of　quantum　dots　or　solvent　chemistry.　Owing　to　the　boundary　of　physically　confined　space,　two　three-phase　border　lines　in　both　the　bottom　center　(horizontal　direction)　and　the　barrier　of　the　bank　substrate　(vertical　direction)　arise,　inducing　dual　capillary　flows　and　Marangoni　backflows.　The　evaporation,　fluid　flow,　and　film-forming　process　in　physically　confined　space　are　studied　by　introducing　well-prepared　single-solvent　quantum　dots　inks.　The　systematical　analysis　offers　valuable　instructions　including　ink　preparation,　surface　modification,　and　postprocessing　evaporation　technique　for　inkjet-printed　patterning　applications,　especially　for　pixelated　display,　polychrome　patterning,　and　sensor　array.
