Abstract

PURPOSE:To obtain a dry direct printing type lithographic plate not deteriorating ink repellency and superior in printing performance, by forming relief image lines made of a photosetting resin, and an ink-repellent nonimage part made of organopolysiloxane on a base. CONSTITUTION:A first layer made of a first photosetting resin, and a second layer made of a second photosetting resin different in solubility in a solvent after photosetting are successively formed on the surface of a base. The first and the second layers are patternwise exposed to light, and only the unexposed part is dissolved off to give the exposed part of the first layer remaining as the relief image lines and the part of the second releasable layer remaining on said relief image lines. All the surface is coated with a layer made of organopolysiloxane, and developed with a solvent dissolving the releasable layer, removing the releasable layer together with said siloxane polymer located just on the releasable layer, thus the intended dry direct printing type lithographic plate is obtained.

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for producing a dry direct printing planographic printing plate using a planographic printing plate.

直刷り平版印刷法(ダイレクト・リングラフイー、以下
ダイリソと称す。)は、従来から湿し水を用いる方法で
感光性平版(presensitized plate
The direct lithographic printing method (hereinafter referred to as dilithography) has conventionally used a method using dampening water to print on a photosensitive lithographic plate (presensitized plate).
.

Hereinafter referred to as the PS version. ) when using a general planographic printing plate, which is used for newspaper printing and other purposes, for die lithography.

Dampening water and ink are applied to each plate, and printing is carried out by bringing the plate and printing material into direct contact. However, with this method, it is difficult to adjust the water supply, resulting in uneven printing, and since it is a lithographic plate, the printing pressure does not increase much, so poor image quality due to poor ink transfer is unavoidable, so it is not recommended as a method for obtaining high-quality printed matter. It's not appropriate.

On the other hand, a method that does not use dampening water has also been put to practical use, but in this case, a plate is used that has a non-image area made of an ink-repellent material and an image area made of an ink-philic material. Since dampening water is not required and no dampening water is used, phenomena such as distortion of the printing paper and emulsification of the ink do not occur, and stable printing can be performed with high printing density, but the printing pressure cannot be increased. However, the image quality still remains unavoidable due to poor ink transfer, and although the printing stability is somewhat improved compared to wet dye lithography, dry dye lithography cannot produce printed matter worthy of the name of high-quality prints.

Dilithographic printing, whether dry or wet, is superior to letterpress printing for things such as halftone photography, but is far inferior to offset printing; In this case, it is slightly better than offset printing, but the reality is that it is inferior to letterpress printing.

また通常の印刷法においては印刷物の画質面のスムース

Furthermore, among ordinary printing methods, offset printing is superior in terms of smoothness of the image quality of printed matter.

The reason offset printing is superior is that it uses a plate, in which some of the ink on the lithographic printing plate is transferred to the blanket, and then the ink is transferred from the plate to the printing substrate again.

Due to the elasticity of the rubber of the planket, the ink is transferred uniformly from the plate, and when transferred to the printing material, unevenness on the surface of the printing material is eliminated by the deformation of the rubber.

Therefore, since printing by die lithography does not use a plunket, the plate and the printing material are not compatible with each other, and the transfer of ink is poor, resulting in an unavoidable drop in image quality.One way to solve this problem is to increase the printing pressure. 1 The plate surface is damaged quickly and is not suitable for practical use.

In printing by die lithography, one way to avoid damage to the plate surface and increase the printing pressure is to make the image area convex and locally increase the printing pressure at the image area.

Furthermore, a layer made of organopolysiloxane is formed on the entire surface of the above intermediate body having the convex image area and the releasable layer on the convex image area. The organopolysiloxane used here is one that cross-links and cures by heating at room temperature after coating to become a silicone rubber elastic body, and is a highly polymerized material in which 090 moles or more of all organic groups bonded to silicon atoms are methyl groups. It is best to use a material mainly composed of organopolysiloxane (which has excellent ink repellency), and K is (

This can be done by a method similar to that used for providing layers made of the first and second photocurable resins. Further, the above-mentioned organopolysiloxane can be cured by leaving it at room temperature or by heating it in an open environment. If the adhesion between the organopolysiloxane and the non-wire part substrate is poor, it can be improved by pretreatment with a crosslinking agent such as a silane coupling agent or an organic titanate.

Next, the above-mentioned organopolysiloxane is coated and cured, and the intermediate layer is developed to dissolve or swell the releasable layer.The surface is then lightly polished to release the releasable layer.

The solvents shown in the table above can be used for the above development, but since the development is carried out through the layer made of the organopolysiloxane described above by immersion in the solvent or by coating, the solvent used for the development is made from organopolysiloxane. It is necessary to select a material that can pass through the other layers and does not melt the organopolysiloxane.

Since the present invention has the above-described configuration, it is possible to easily produce a printing plate with excellent printing effect with less damage to the plate when used in dry printing, and the non-image area has ink repellency. Since organopolysiloxane with excellent properties can be used without modification, the ink repellency does not deteriorate as in the case of using photosensitive silicone or a mixture of silicone and a photosensitive substance. Both steps can be carried out using known methods and materials, and therefore are not industrially viable.

[Scope of Claims] A layer consisting of a first photocurable resin on the surface of the substrate;
A layer made of a photocurable resin and a layer made of a second photocurable resin having different solubility or swelling properties in a solvent after photocuring are successively provided. The layer made of the resin is pattern-exposed and only the uncured portions caused by the exposure are dissolved and removed, so that a part of the layer made of the first photocurable resin hardens and remains on the surface of the substrate 7, resulting in a famous curved image area. and,
A part of j made of the second photocurable resin is cured in the convex image area L to form a releasable layer that swells or dissolves with the remaining solvent and separates, and then the entire surface is coated with organoleptic resin. Form a layer consisting of polysiloxane. Thereafter, development is performed using a solvent that swells or dissolves the releasable layer to release the releasable layer and at the same time remove the layer made of organopolysiloxane on the releasable layer. Method of manufacturing lithographic printing plates.
