There is no background smearing in the ink that is used.
This invention relates to a printing ink for dry planography that provides good printing effects.

点がある。しかし、現在のところ乾式平版印刷では、非
画線部のインキ反発性が十分でないため。(Prior art) Currently, in the normal lithographic printing method, it is necessary to supply dampening water at the same time as ink is supplied to the plate, which improves ink adhesion to printed areas and non-printed areas. A difference is provided to form an ink image. However, by using dampening water,
In recent years, dry lithographic printing without the use of dampening water has been carried out because problems such as background smearing due to emulsification of ink and changes in dimensions of printing paper occur. In dry lithographic printing, the non-image areas are usually formed with a silicone layer, and the resilience of silicone is used to create a difference in ink adhesion between the image areas and the non-image areas.
Form an ink image. Since this printing method does not use dampening water, it does not have the problems described above that occur with normal printing methods (9) and has various advantages such as being able to increase the amount of ink applied.However, at present, dry lithographic printing This is because the ink repulsion in the non-printing area is not sufficient.

く２版面の温度が通常の平版印刷方式の場合よりも著し
く高（なり、このため非画線部へのインキの付着が促進
されるものと推定される。Not only when using normal lithographic printing ink that requires dampening water, but even when using dry lithographic printing ink, as the temperature of the printing press increases, ink may adhere to non-image areas. It cannot withstand long-term printing because of the stains caused by this. In other words, in dry lithographic printing, there is no cooling effect using dampening water, so the heat generated by contact between rollers and contact between rollers and plate surface is dissipated only by air, which is not sufficient. The temperature of the plate surface is significantly higher than in the case of normal planographic printing, and it is presumed that this promotes the adhesion of ink to non-image areas.
従来、インキ面からの対応としては９版面塩度の上昇を
見込んで予めインキの粘度を高く調整しておくことが行
われているが、それでも印刷機の使用の状況によっては
９版面塩度の上昇が予想を上回り。Conventionally, as a countermeasure from the ink side, the viscosity of the ink has been adjusted to be high in advance in anticipation of an increase in the salinity of the 9th plate, but even so, depending on the usage conditions of the printing press, the salinity of the 9th plate may increase. The increase exceeded expectations.

、冷却水の冷却装置等の設備に費用がかかり、また冷却
装置の運転費用も大きなものとなる。In addition, printing machines have taken measures such as controlling the rise in plate surface temperature by passing cooling water through some of the kneading rollers. This method is one of the most effective methods for controlling the temperature rise of a printing press, but on the other hand, it is expensive to improve the printing press and equipment such as a cooling water cooling device. The operating cost of the cooling device is also large.

明（特開昭６Ｏ−１３２７８３）され。In order to reduce the cost required for cooling, a dry lithographic printing method was invented (Japanese Patent Application Laid-Open No. 60-132783) in which the ink mixing roller of a printing press is humidified and cooled.

When humidified with water, uneven inkling may occur on printed matter.
（発明が解決しようとする問題点）
印刷機のインキ練りローラーを加湿、冷却する乾式平版
印刷法において、加湿条件の変動に対する許容度が大き
く、良好な印刷効果を与えるインキが望まれていた。(Problems to be Solved by the Invention) In a dry planographic printing method in which the ink mixing roller of a printing press is humidified and cooled, there has been a desire for an ink that has a high tolerance to fluctuations in humidification conditions and provides good printing effects.

平版用印刷インキである。(Means for Solving the Problems) According to the present invention, a mixing roller of an inking device is humidified with water and/or a low-boiling alcohol. In the ink used for the printing method using dry lithography, the emulsification accelerator is added in the range of 0.01 to 5.
It is a printing ink for dry planography containing 0% by weight, preferably 0.1 to 30% by weight.

It may be any roller such as a rider roller, a horizontal swing roller, or an intermediate rubber roller. The humidifying means is provided at one or more places in a part of the mixing roller of the inking device, and the humidifying means may be either a contact type or a non-contact type with respect to the mixing roller, but it is preferable to use a good humidifier. The device of the means is two ordinary kneading rollers,
It is preferable to use a device that is installed parallel to the longitudinal direction of the kneading roller and can humidify almost uniformly in the longitudinal direction of the kneading roller. good. Furthermore, a method of continuously supplying humidification is usually preferred.

Additives such as surfactants can also be added to the humidifying liquid as needed. Surfactant The emulsification accelerator according to the present invention may be one that has the ability to quickly emulsify humidified water and/or low-boiling alcohol. Therefore, there are many types of emulsification accelerators that can be used, including: ■ Various surfactants such as nonionic, anionic (including metal soaps and rosin soaps), cationic, amphoteric, or fluorine-based, ■ paraffin-based, Oxides, acid-modified products, or derivatives such as metal salts and esters of waxes such as microcrystalline and polyethylene waxes; ■Derivatives such as organic acids including rosin, their acid-modified products, or their esterification products; The temperature is 180°C or higher.

対する許容度が不足し好ましくない。The amount of emulsification promoter added varies depending on the type of emulsification promoter used, but if it is less than 0.01% by weight, even if a surfactant with good additive effect is used, it will not tolerate fluctuations in humidification conditions. The degree is insufficient and undesirable.
５０重量％より多い場合は印刷インキの持つ通性や効果

ものと想定される。In addition to the original objective of preventing background smudges due to temperature rise, there are also advantages when printing with a dry planographic printing ink containing the emulsification accelerator of the present invention while humidifying and cooling. This has the effect of reducing the amount of paper generated and improving the paper release properties from the blanket. It is assumed that the reason why such an effect was obtained is that the ink is easily turned into a uniform emulsion by humidified water and/or a low boiling point alcohol, which improves electrical and fluid properties.
