Abstract
Herein is disclosed a method of transfer inkjet printing comprising jetting a radiation curable inkjet ink onto an intermediate transfer member of an inkjet printer to form an image; irradiating the radiation curable inkjet ink on the intermediate transfer member to form an at least partially cured image; and transferring the at least partially cured image to a substrate to form a printed substrate. Herein is also disclosed a transfer inkjet printing apparatus adapted, in use, to perform the method.
Claims20
A method of transfer inkjet printing comprising:
- jetting a radiation curable inkjet ink including a photoinitiator onto an intermediate transfer member of an inkjet printer to form an image, wherein the radiation curable inkjet ink comprises a liquid carrier;
- at least partially drying the radiation curable inkjet ink before irradiating the radiation curable inkjet ink, wherein at least partially drying the inkjet ink comprises removing at least 50 wt. % of liquid carrier from the inkjet ink;
- irradiating the radiation curable inkjet ink on the intermediate transfer member to form an at least partially cured image;
- and
- transferring the at least partially cured image to a substrate to form a printed substrate.
A transfer inkjet printing apparatus comprising:
- an intermediate transfer member;
- an inkjet print head;
- and
- a radiation source;
- wherein the transfer inkjet printing apparatus is adapted, in use, to jet a radiation curable inkjet ink including a photoinitiator onto the intermediate transfer member, wherein the radiation curable inkjet ink comprises a liquid carrier;
- at least partially dry the radiation curable inkjet ink before irradiating the radiation curable inkjet ink by removing at least 50 wt. % of liquid carrier from the inkjet ink;
- and irradiate the radiation curable inkjet ink to at least partially cure the radiation curable inkjet ink on the intermediate transfer member.
