Summary:A digital offset printing architecture requires an offset type ink which is particularly designed and optimized to be compatible with different sub-systems including an ink delivery system and an imaging system enabling a high quality printing process to be performed at a high speed without residues. The present invention relates to an aqueous ink composition comprising: water; an optional co-solvent; an optional coloring agent; a polyester; and a polymer additive, wherein the polymer additive is selected from members of the group consisting of styrene-butadiene, acrylonitrile-butadiene, acrylonitrile-butadiene-styrene, and combinations thereof. The present invention relates to a digital offset printing method comprising: a step of allowing the re-imageable imaging member to have a dampening fluid disposed on an image thereof as a step of applying an ink composition to the surface of a re-imageable imaging member at an ink take up temperature; a step of forming an ink image; and a step of transferring the ink image from a re-imageable surface of the imaging member to a printable base material at an ink transfer temperature. The present invention relates to a method comprising the step of forming an aqueous ink composition by mixing water, an optional co-solvent, an optional coloring agent, a polyester, and a polymer additive, wherein the polymer additive is selected from members of the group consisting of styrene-butadiene, acrylonitrile-butadiene, acrylonitrile-butadiene-styrene, and combinations thereof. 본 발명은 물; 선택적 공용매; 선택적 착색제; 폴리에스테르; 및 폴리머 첨가제를 포함하되, 폴리머 첨가제가 스티렌-부타디엔, 아크릴로니트릴-부타디엔, 아크릴로니트릴-부타디엔-스티렌, 및 이들의 조합으로 구성되는 군의 구성원으로부터 선택되는 수성 잉크 조성물에 관한 것이다. 본 발명은 잉크 조성물을 잉크 테이크 업 온도에서 재이미지화 가능한 이미지화 부재 표면 상으로 도포하는 단계로서, 상기 재이미지화 가능한 이미지화 부재는 그 상에 배치되는 축임 유체를 가지는, 단계; 잉크 이미지를 형성하는 단계; 잉크 이미지를 잉크 전사 온도에서 이미지화 부재의 재이미지화 가능한 표면으로부터 인쇄가능 기재로 전사시키는 단계를 포함하는 디지털 오프셋 인쇄 방법에 관한 것이다. 본 발명은 물, 선택적 공용매, 선택적 착색제, 폴리에스테르, 및 폴리머 첨가제를 배합하여 수성 잉크 조성물을 형성하는 단계를 포함하며, 상기 폴리머 첨가제는 스티렌-부타디엔, 아크릴로니트릴-부타디엔, 아크릴로니트릴-부타디엔-스티렌, 및 이들의 조합으로 구성되는 군의 구성원으로부터 선택되는 방법에 관한 것이다.
