The present invention relates to an ink composition which comprises: a humectant blend including a first humectant and a second humectant, wherein the first humectant has a freezing point and the second humectant includes a humectant blend, for example, which inhibits the freezing point of the first humectant to give the ink composition the ability to be stored at the desired temperature without solidification; water; a selective cosolvent; a selective colorant; and sulfonated polyester, and to a digital offset printing method using the ink composition. 본 발명은 제1 휴멕턴트 및 제2 휴멕턴트를 포함하는 휴멕턴트 블렌드로서, 상기 제1 휴멕턴트는 빙점을 가지며; 상기 제2 휴멕턴트는 예컨대 잉크 조성물에 고화 없이 원하는 온도에서 저장될 수 있는 특성을 부여하기 위해 제1 휴멕턴트의 빙점을 억제하는, 휴멕턴트 블렌드; 물; 선택적 공용매; 선택적 착색제; 및 설폰화된 폴리에스테르를 포함하는 잉크 조성물에 관한 것이다. 본 발명은 잉크 조성물을 사용하는 디지털 오프셋 인쇄 방법에 관한 것이다.
