To provide a gravure printing machine which can achieve improvements in exhaust performance and printing quality.SOLUTION: A tip of a doctor blade comes into contact with an outer peripheral surface of a plate cylinder 40 which is oriented toward a pressure contact part with an impression cylinder from a pressure contact part with a furnisher roll 50 which is rotated in a state that a lower part thereof is immersed in an ink accumulated in an ink pan 4. A local air exhaust structure which discharges air around the plate cylinder 40, comprises: a partition plate 70 which is so located as to partition between the furnisher roll 50 and a web; a pan cover 100 which is so configured as to partition a local space LS which extends below the partition plate; and an air discharge device which is connected to the local space LS.SELECTED DRAWING: Figure 8 【課題】排気性能及び印刷品質の向上が図れるグラビア印刷機を提供する。【解決手段】インキパン４に溜まるインキに下部が浸漬された状態で回転するファニッシャーロール５０との圧接部位から、圧胴との圧接部位に向かう、版胴４０の外周面に、ドクターブレードの先端が接している。版胴４０の周囲の空気を排気する局所排気構造が、ファニッシャーロール５０とウエブとの間を仕切るように配置された区画プレート７０と、区画プレートの下側に拡がる局所空間ＬＳを仕切るように構成されたパンカバー１００と、局所空間ＬＳと接続された排気装置とを有している。【選択図】図８
