。(Prior art) In lithographic ink such as offset printing, a printing plate is composed of a lipophilic image area that receives printing ink and a hydrophilic non-image area that accepts dampening water and repels printing ink. Since this is a printing method that uses , both printing ink and dampening water are supplied onto the printing plate surface during printing. As printing progresses, the ink deposit passes from the ink fountain to the mixing rollers, and the dampening water gradually emulsifies into the printing ink that is supplied to the printing area on the printing plate by the rollers. The ink buildup progresses not only to the printing ink but also to the printing ink on the rollers and kneading rollers. This emulsification phenomenon occurs when the rubber roller and metal roller rotate in contact with each other, and when the ink adheres to the plate surface, the printing ink and dampening water are subjected to pressure and shear deformation in the nip between the rollers, and are agitated. It happens. Furthermore, this emulsification behavior is greatly influenced by the surface chemical or rheological properties of the printing ink, the relative amounts of the printing ink and the dampening solution, and the surface tension of the dampening solution. .

生する。In addition, there are many printing problems caused by emulsification phenomena1, such as stains, roll accumulation, baldness of the base roll, roll stripping, ghosting, slow drying, deterioration of gloss, and deterioration of 111-point reproducibility. All of these phenomena occur when the printing ink and dampening water are not properly emulsified.

ンキの物性をいかにコントロールするかが最大の課題で
あるといっても過言ではない。Therefore, for those involved in related industries such as offset printing, especially in the printing ink manufacturing industry, it is important to know how to control the physical properties of the printing ink that affect this in order to maintain proper emulsification between the printing ink and the dampening solution. It is no exaggeration to say that this is the biggest challenge.
従来、印刷インキと湿し水との乳化に関し１通常行われ
て来た試験法は、一定量の印刷インキと湿し水とをハイ
スピードミキサーで強制攪拌して乳化させた後、一定の
シェアーで過剰の湿し水を除き、キシレン還流法で乳化
した湿し水の量を測定するか。Conventionally, the conventional test method for emulsification of printing ink and dampening water is to forcibly stir a certain amount of printing ink and dampening water with a high-speed mixer to emulsify it, and then Remove excess dampening water and measure the amount of dampening water emulsified using the xylene reflux method.

化させてから乳化インキをローラ上よりかき取り、カー
ルフィッシャー法で乳化した湿し水量を定量測定する。After supplying a certain amount of printing ink to a group of rollers that rotate in contact with each other, such as the Lyso Break Tester (manufactured by THWING-ALBERT), dampening water is brought into contact with the roller at the end for a certain period of time, and the roller After the printing ink above is emulsified, the emulsified ink is scraped off from the roller, and the amount of emulsified dampening water is quantitatively measured using the Karl Fischer method.
というものであった。That's what it was.
しかしながら、乳化挙動の本質を把握するには。However, to grasp the essence of emulsification behavior.
上記試験法の如く、印刷インキ中に乳化し得る湿し水の
量だけでなく、乳化挙動、すなわち印刷インキと湿し水
とがローラニップ間でどのように乳化して行くかを正確
に把握することが不可決である。As with the above test method, it is necessary to accurately grasp not only the amount of dampening water that can be emulsified in printing ink, but also the emulsification behavior, that is, how printing ink and dampening water emulsify between the roller nip. This is uncertain.
従来より当該業界における強い要望をあるにもかかわら
ず、ローラニップ間の乳化状態を観察することの可能な
装面、方法がなかった。Although there has been a strong demand in the industry, there has been no equipment or method for observing the emulsification state between the roller nips.

ことが行われていた。しかしながら、これらの装置では
、実際の印刷装置で起っている乳化挙動を観察すること
はできない。Note that the only conventional devices for checking the emulsified state were an optical microscope or an electron microscope. When using these devices, first scrape the emulsified ink directly onto the rollers of the printing press to obtain an emulsified sample, or scrape the emulsified ink from the rollers of an emulsification tester such as the Tube Break Tester. Secondly, these samples were observed using an optical microscope, or the samples were frozen and their cut surfaces were observed using an electron microscope. However, with these devices it is not possible to observe the emulsification behavior occurring in an actual printing device.
また、特開昭５７−３５１１３号公報のように。Also, as in Japanese Patent Application Laid-Open No. 57-35113.

をするものではない。Devices for monitoring the equilibrium state of fountain solution and printing ink in offset printing devices are also known. With this device, it is possible to know the amounts of dampening water and printing ink during printing. However, it does not even know the emulsification state, but instead measures the amount of dampening water and printing ink using a receiver (sensor). Moreover, it is not intended for observation between the roller nips.

There is no particular limitation as long as it can be observed with the naked eye. As the magnifying observation device, an optical microscope, which is a commonly used magnifying optical system, is preferable, and a photographic camera can also be attached to the optical microscope for recording. It is also possible to use a CCD camera with an optical system for magnification as a magnifying observation device.

ッタースピードを上げることで、静止像が記録できる。The required flash duration varies depending on the circumferential speed of the 3-rotation roller, the magnification of the magnifying observation device, and the size of the object to be observed, but a high-speed flash duration with a half-width of around 1/1 millionth of a second has the highest resolution. This is suitable for obtaining good [phase] static images. However, if the roller rotation speed is relatively slow, a regular tungsten lamp or halogen tungsten lamp that generates continuous light can be used as the light source for the illumination device.In this case, the shutter speed of the photo camera attached to the magnifying observation device By raising it, a still image can be recorded.
