INKJET PRINTING METHOD
Document Type and Number:
WIPO Patent Application WO/2013/088549
Kind Code:
A1
Abstract:
The purpose of the invention is to provide an inkjet printing method with which a high level of image blur-inhibiting effects is obtained. An inkjet printing method comprising a process of printing the contour region of an image by applying a first pigment-containing black ink from an inkjet print head on a print medium, and a process of printing the internal region of the image by applying a second pigment-containing black ink from an inkjet print head on the print medium. The inkjet printing method is characterized in that the dynamic surface tension γ1 of the first black ink by the maximum bubble pressure method at a lifetime of 100 msec and the dynamic surface tension γ2 of the second black ink by the maximum bubble pressure method at a lifetime of 100 msec satisfy the relationships in Condition (1): γ1 > γ2, Condition (2): γ1 - γ2 ≤ 20 mN/m, Condition (3): 40 mN/m ≤ γ1, and Condition (4): 34 mN/m ≤ γ2.
