の粘度が変化し、印刷性能が次第に変わり、印刷物の品
質の均一性が保てなかった。Problems to be Solved by the Invention Conventional ink management was mainly carried out only before printing as described above, so when the ink is moved on the screen with a squeegee and scraper during actual printing, the viscosity of the ink changes. As a result, the printing performance gradually changed, and the quality of printed matter could not be maintained uniformly.
また、印刷機を設置しである場所の環境条件が変化した
場合や印刷機からの発熱によりインク温度が変化した場
合などでもインク粘度が変化し、印刷安定性が損われる
という欠点があった。Another disadvantage is that the viscosity of the ink changes when the environmental conditions of a certain location change after the printing machine is installed, or when the temperature of the ink changes due to heat generated by the printing machine, which impairs printing stability.
そこで、本発明は印刷時にスクリーン上に存在するイン
クの粘度を最適な値に常に制御し印刷安定性を高めるこ
とを目的とする。Therefore, an object of the present invention is to constantly control the viscosity of the ink present on the screen at the time of printing to an optimal value to improve printing stability.

給装置を付加したものである。Means for Solving the Problems The screen printing machine of the present invention comprises a screen on which a desired printing pattern is arranged, a squeegee that pushes the ink on the screen from the screen onto the substrate, and a uniform thickness of the ink on the screen. Equipped with a scraper, etc., an ink viscosity meter is placed between the squeegee and the scraper, an ink viscosity adjustment device that operates based on the output signal from this viscometer, and an ink supply device that supplies ink whose viscosity is controlled by this device onto the screen. It is.

た印刷性が得られる。Effect: According to the above configuration, the viscosity of the ink on the screen during printing can always be controlled to be constant. That is,
It is possible to prevent changes in ink viscosity that occur when the environmental conditions at the location where the printing machine is installed or when the ink temperature changes due to heat generation from the printing machine, thereby increasing the stability of printing. Further, even when the lot of ink to be supplied changes and the ink viscosity changes, the ink supply device of the present invention manages the ink viscosity on the screen, so stable printing performance can be obtained.

になるようにインク調整機8に信号を送る。A screen 3 is installed between a squeegee 1 that serves to push ink 4 from a screen 3 on which a desired printing pattern is arranged onto a substrate (not shown) and a scraper 2 that serves to spread the ink 4 uniformly onto the screen 3. A viscometer sensor section 6 for measuring the viscosity of the upper ink 4 is installed, and is positioned so that the sensor section enters into the ink and does not come into contact with the screen 3. The viscometer sensor section 6 is connected to a viscometer 7, and sends a signal to the ink regulator 8 so that the ink viscosity becomes a predetermined value.

理は行われておらず、印刷運転中のインク粘度の変化に
より印刷性が変わり、印刷安定性に問題があった。Conventionally, before printing, the ink viscosity was measured using a viscometer, and the ink was adjusted to a predetermined viscosity and then supplied onto the screen with a brush or the like, or placed in an ink reservoir of an ink supply machine. That is, although ink was controlled before printing, it was not controlled during printing, and printability changed due to changes in ink viscosity during printing operation, resulting in problems with printing stability.

In the GL1 machine, the viscosity of the ink actually being printed is constantly controlled during printing operation. In other words, the viscosity of the printed ink remains constant even if the environmental conditions change, the temperature of the ink increases due to heat generated by the printing machine, or if a different lot of ink is refilled. .
