An apparatus for printing on curved glass, according to one embodiment, comprises: a pattern roller having grooves formed on the surface thereof and having a pattern for receiving a printing material; a transfer roller for contacting and rotating the pattern roller to transfer the printing material from the pattern roller to the surface thereof, and print the transferred printing material on the surface of the curved glass; and a blade, provided so as to be in contact with the surface of the pattern roller, for removing, from the surface of the pattern roller, the printing material attached to portions other than the pattern, as the pattern roller rotates, wherein the transfer roller may have, on the surface thereof, protrusions having a shape corresponding to a curved portion of the curved glass. Dans un mode de réalisation, l'invention concerne un appareil d'impression sur du verre bombé, comprenant : un rouleau à motif comportant des rainures formées sur sa surface et pourvu d'un motif destiné à recevoir un matériau d'impression ; un rouleau de transfert destiné à mettre en contact et à faire tourner le rouleau à motif pour transférer le matériau d'impression dudit rouleau à la surface du verre bombé, et à imprimer le matériau d'impression transféré sur la surface du verre ; et une lame, disposée de sorte à être en contact avec la surface du rouleau à motif, pour retirer de la surface du rouleau le matériau d'impression fixé sur des parties autres que le motif, à mesure que ledit rouleau tourne, le rouleau de transfert pouvant comporter, sur sa surface, des éléments saillants présentant une forme correspondant à une partie bombée du verre bombé. 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, 표면에 상기 곡면 글래스의 곡면부에 대응하는 형상을 가진 돌출부가 형성되는 것일 수 있다.
