得る。In general, planographic printing is a printing method that uses water and lipophilic ink to print.The image area of the printing plate has a lipophilic surface, and the non-image area has a hydrophilic surface. A lipophilic ink is applied only to the paper, and this is transferred to the paper to obtain a printed matter.

という問題があった。However, the former requires time in the process of producing a film with an image pattern recorded from the printing plate, and the process of removing the exposed or unexposed photosensitive material after exposure, and the latter also requires time to create a film with an image pattern recorded on it. After fixing, a step of etching the non-image area to make it hydrophilic is required, resulting in a problem of poor working efficiency.

版が可能となる。That is, using a lithographic printing plate in which a surface member coated on a support such as a metal plate, a plastic plate, or a paper board is treated to have hydrophilic properties, the printing plate is made water repellent. A volatile organic solvent in which a substance is dissolved is ejected according to image information using an inkjet method. As a result, the organic solvent in which the ↑θΩ aqueous substance is dissolved quickly swells, and the water-repellent substance adheres only to the areas where the water-repellent substance has been sprayed onto the lithographic printing plate having a hydrophilic surface. The areas on which the water-repellent substance has been sprayed become more lipophilic than the surface of the lithographic printing plate that has not been sprayed with the organic solvent in which the aqueous substance has been dissolved. It is possible to form an image area with a hydrophilic surface and a non-image area with a hydrophilic surface, making it possible to make a lithographic printing plate with high work efficiency.
