Abstract
Official abstract text for this publication.
An oil-based inkjet ink set including two or more liquid compositions, for use with an inkjet head having two or more discharge port arrays, wherein at least one of the two or more liquid compositions is an oil-based inkjet ink, the initial boiling point of each of the two or more liquid compositions is, independently, 280° C. or higher, and the difference in the specific gravities of any pair of liquid compositions in the two or more liquid compositions is at least 0.005 but not more than 0.012, is disclosed. A method for producing a printed item is also disclosed.
First claim
Opening claim text (preview).
What is claimed is: 1. An oil-based inkjet ink set comprising two or more liquid compositions, for use with an inkjet head having two or more discharge port arrays, wherein at least one of the two or more liquid compositions is an oil-based inkjet ink, an initial boiling point of each of the two or more liquid compositions is, independently, 280° C. or higher, and a difference in specific gravities of any pair of liquid compositions in the two or more liquid compositions is at least 0.005 but not more than 0.012. 2. The oil-based inkjet ink set according to claim 1 , wherein an 80% distillation temperature of each of the two or more liquid compositions is, independently, from 300 to 350° C. 3. The oil-based inkjet ink set according to claim 1 , wherein a specific gravity of each of the two or more liquid compositions is, independently, 0.890 or less. 4. A method for producing a printed item, the method comprising discharging two or more liquid compositions from an inkjet head having two or more discharge port arrays onto a recording medium, wherein at least one of the two or more liquid compositions is an oil-based inkjet ink, an initial boiling point of each of the two or more liquid compositions is, independently, 280° C. or higher, and a difference in specific gravities of any pair of liquid compositions in the two or more liquid compositions is at least 0.005 but not more than 0.012. 5. The method for producing a printed item according to claim 4 , wherein an 80% distillation temperature of each of the two or more liquid compositions is, independently, from 300 to 350° C. 6. The method for producing a printed item according to claim 4 , wherein a specific gravity of each of the two or more liquid compositions is, independently, 0.890 or less.
