Definitions
- the present invention relates to a waterless lithographic printing plate precursor that can be printed without using dampening water.
- Waterless lithographic printing uses the difference in ink adhesion, with the image area and non-image area on the same plane, with the image area as the ink receiving layer and the non-image area as the ink repellent layer. This is a lithographic printing method in which ink is applied only to the image area and then transferred to a printing medium such as paper, and printing is performed without using dampening water.
- Various methods have been proposed as the exposure method for waterless lithographic printing plate precursors: a method of irradiating ultraviolet rays through an original film, and a computer tow that writes an image directly from an original without using the original film Broadly divided into plate (CTP) systems.
- CTP plate
- Examples of the CTP method include a method of irradiating a laser beam, a method of writing with a thermal head, a method of partially applying a voltage with a pin electrode, and a method of forming an ink repellent layer or an ink receiving layer with an ink jet.
- the method using laser light is superior to other methods in terms of resolution and plate making speed!
- a waterless lithographic printing plate precursor includes a photosensitive (thermal) layer removing type in which a photosensitive (thermal) layer is removed in an exposure process or a development process, and a photosensitive (thermal) process even after passing through an exposure process and a development process. It is roughly divided into photosensitive (thermal) layer remaining type in which the layer remains. Since the photosensitive (thermal) layer is removed in the photosensitive (thermal) layer removal type, the ability to provide color contrast between the image area and the non-image area by including a colored dye in the photosensitive (thermal) layer S Is possible. For this reason, it has the merit that plate inspection can be performed without a post-staining step. However, since the depth of the cell forming the image area is deep, a large amount of ink is required for printing. Also, since it is necessary to remove the photosensitive (thermal) layer in the depth direction, it is difficult to reproduce fine images!
- a heat-sensitive layer remaining type having at least a heat-sensitive layer and a silicone rubber layer on a substrate Waterless CTP lithographic printing plate precursor has been proposed.
- the heat-sensitive layer in the laser-irradiated area remains even after development, so that the reproducibility of fine images with a small amount of ink used for printing is good.
- since exposure can be performed with a low laser output not only is it advantageous in terms of running cost and laser life, but also no ablation force is generated during laser irradiation, so that no special suction device is required.
- a heat-sensitive layer remains in both the laser-irradiated part and the non-irradiated part, color contrast between the laser-irradiated part and the non-irradiated part can be obtained ⁇ and plate inspection is difficult.

- the plate inspection property of the waterless planographic printing plate after exposure and development is good.
