Abstract
An inkjet printing method includes, in order, the steps of a) providing to an inkjet printer at least two or more colorless liquids having a different composition and at least one color inkjet ink; b) mixing the color inkjet ink in a controlled amount with the two or more colorless liquids; and c) printing the ink-mixture of the color inkjet ink and the two or more colorless liquids with the inkjet printer onto an ink-receiver.
Claims12
A color inkjet ink set comprising:
- two or more colorless liquids having a different composition;
- at least one radiation curable color inkjet ink containing a colorant;
- wherein the colorant is a pigment;
- and
- the two or more colorless liquids and the at least one radiation curable color inkjet ink include a polymerizable compound, and an amount and/or type of the polymerizable compound in at least one of the two or more colorless liquids differs from an amount and/or type of the polymerizable compound in the at least one radiation curable color inkjet ink;
- wherein
- a surface tension of at least one of the two or more colorless liquids differs by more than 3.0 mN/m from a surface tension of the at least one radiation curable color inkjet ink.
