Abstract
The present invention provides an ink jet recording method and an ink jet recording apparatus for recording an image on a recording medium by using an ink containing a coloring agent and a liquid composition containing a component for coagulating and/or thickening the ink. The method is characterized in that the ink and the liquid composition are ejected onto the recording medium such that they are not in contact with each other on the recording medium immediately after the ejection and come into contact when a certain period of time has lapsed since the application.
Claims18
An ink jet recording method comprising recording an image on a recording medium with an ink containing a coloring agent and a liquid composition containing a component for coagulating and/or thickening the ink, wherein the ink and the liquid composition are applied to the recording medium such that the ink and the liquid composition are not in contact with each other on the recording medium immediately after the application and come into contact with each other when a certain period of time has elapsed since the application;
- wherein the ink is applied to an image area and is not applied to a non-image area, the liquid composition is applied to the non-image area, and the ink or the liquid composition is applied to a boundary portion of the image area or a boundary portion of the non-image area under one of the following conditions (1) to (3):
- (1) the liquid composition is not applied to the boundary portion of the non-image area;
- (2) the application amount of the liquid composition in the boundary portion is smaller than that in a portion other than the boundary portion;
- and
- (3) the application amount of the ink in the boundary portion is smaller than that in a portion other than the boundary portion, or the application amount of the liquid composition in the boundary portion is smaller than that in a portion other than the boundary portion.
An ink jet recording apparatus comprising a recording head for applying an ink containing a coloring agent and a liquid composition containing a component for coagulating and/or thickening the ink, to a recording medium, and a unit for controlling the positions of droplets of the ink and the liquid composition such that the ink and the liquid composition are not in contact with each other on the recording medium immediately after the application and come into contact with each other when a certain period of time has lapsed since the application, wherein the ink is applied to an image area and is not applied to a non-image area, the liquid composition is applied to the non-image area, and the ink or the liquid composition is applied to a boundary portion of the image area or a boundary portion of the non-image area under one of the following conditions (1) to (3):
- (1) the liquid composition is not applied to the boundary portion of the non-image area;
- (2) the application amount of the liquid composition in the boundary portion is smaller than that in a portion other than the boundary portion;
- and (3) the application amount of the ink in the boundary portion is smaller than that in a portion other than the boundary portion or the application amount of the liquid composition in the boundary portion is smaller than that in a portion other than the boundary portion.
