Problems solved by technology
[0005] However, when recording is performed on a non-(low) absorptive recording medium having irregularities on the surface using a treatment liquid and an ink composition containing a nitrogen-containing solvent, there is a problem that the obtained image has poor abrasion resistance.
As a reason, it is presumed that, for example, when the unevenness of the recording medium is large, the processing liquid flows from the convex part into the concave part, the solubility of the resin contained in the ink on the convex part is insufficient, and the abrasion resistance of the obtained image is poor.
Therefore, it is also considered to increase the nitrogen-containing solvent in the ink, but when the nitrogen-containing solvent in the ink is increased, the resin contained in the ink in the ink-jet head will dissolve and cause the ink-jet head and nozzles to clog, and the ejection stability of the ink will be reduced. reduce

Embodiment Construction
[0045] Next, preferred embodiments of the present invention will be described. The embodiments described below illustrate an example of the present invention. In addition, this invention is not limited to the following embodiment, It also includes the various modified examples implemented in the range which does not change the gist of this invention.
[0046] The inkjet recording method according to the present embodiment is characterized in that it includes a treatment liquid adhering step in which the treatment liquid having a nitrogen-containing solvent content higher than that of the ink composition is attached to the surface with a height difference of at least 10 μm. Absorptive or non-absorptive recording medium; and an ink adhering process, the said ink composition containing nitrogen-containing solvent is ejected from the inkjet head to the recording medium subjected to the said treatment liquid adhering process, and attached to the said processing liquid adhering proc...

Abstract
The invention provides an ink jet recording method and a method of controlling an ink jet recording apparatus which are capable of forming an image excellent in abrasion resistance and having excellent discharging stability of ink. The ink jet recording method includes attaching a treating liquid, in which a content of a nitrogen-containing solvent is greater than that of an ink composition, to arecording medium having low or non-absorbability in which a step of surface unevenness is equal to or greater than 10 [mu]m, and attaching the ink composition containing the nitrogen-containing solvent by discharging the ink composition from an ink jet head to the recording medium to which the treating liquid is attached.
Description
technical field [0001] The present invention relates to an inkjet recording method and a control method for an inkjet recording device. Background technique [0002] An inkjet recording method is known in which fine ink droplets are ejected from a nozzle of a recording head of an inkjet recording device to record an image on a recording medium, and its application to the fields of label printing and high-speed label printing is being studied. Moreover, when recording an image on a recording medium with low ink absorption (for example, coated paper, coated paper) or an ink non-absorptive recording medium (for example, a plastic film), as an ink, from the perspective of the global environment and the From the viewpoint of the safety of the human body, etc., the use of a water-based resin ink composition (hereinafter also referred to as "water-based ink" or "ink") containing a resin emulsion is being studied. And when using the water-based resin ink composition to record on th...
