Abstract
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.
Claims6
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.
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.
