One embodiment of a curved glass printing apparatus comprises: a pattern roller having patterns which are provided as grooves in the surface thereof and accommodate a printing material; a transfer roller which comes into contact with the pattern roller and rotates such that the printing material is transferred from the pattern roller to the surface thereof, and which prints the transferred printing material onto the surface of curved glass; and a blade which is provided so as to contact the surface of the pattern roller and which, as the pattern roller rotates, removes the printing material attached to portions other than the pattern from the surface of the pattern roller. The transfer roller may include a core roll coupled to a rotary shaft, and a surface layer made of a flexible material and stacked on the core roll. Selon un mode de réalisation, la présente invention concerne un appareil d'impression à verre bombé comprenant : un rouleau à motif présentant des motifs qui sont disposés sous la forme de rainures dans sa surface et qui reçoivent un matériau d'impression ; un rouleau de transfert qui vient en contact avec le rouleau à motif et tourne de telle sorte que le matériau d'impression soit transféré du rouleau à motif à sa surface, et qui imprime le matériau d'impression transféré sur la surface du verre bombé ; et une lame qui est disposée de façon à entrer en contact avec la surface du rouleau à motif et qui, lorsque le rouleau à motif tourne, retire de la surface du rouleau à motif le matériau d'impression fixé à des parties autres que le motif. Le rouleau de transfert peut comprendre un rouleau central accouplé à un arbre rotatif et une couche superficielle constituée d'un matériau souple et empilée sur le rouleau central. 곡면 글래스 인쇄장치의 일 실시예는, 표면에 홈으로 구비되고 인쇄물질이 수용되는 패턴이 형성되는 패턴롤러; 상기 패턴롤러와 접촉 및 회전하여 상기 패턴롤러로부터 인쇄물질이 표면에 전사되고, 전사된 인쇄물질을 곡면 글래스의 표면에 인쇄하는 전사롤러; 및 상기 패턴롤러의 표면과 접촉하도록 구비되고, 상기 패턴롤러가 회전함에 따라 상기 패턴롤러의 표면에서 상기 패턴 이외의 부위에 부착된 인쇄물질을 제거하는 블레이드를 포함하고, 상기 전사롤러는, 회전축과 결합하는 코어롤(core roll); 및 상기 코어롤 상에 적층되어 형성되는 유연한(flexible) 재질의 표면층을 포함할 수 있다.
