Paper Abstract

In the procedure of printing progress epically for multicolor printing, better ink controlling is very necessary and important to obtain high printing quality products and presswork and it is very crucial to monitor the ink on-line in the printing procedure. Automatic printing inking-up has become one important research topic in the field of printing industrial production and automatic control. This paper presents a method for monitoring and controlling the printing ink in the press ink fountain automatically using one controlled system based on ultrasonic sensor. Firstly, physical properties and the installation location of the ultrasonic sensor is explained and analyzed and one monitoring system consists of ultrasonic emitter, ultrasonic acceptor, voltage-magnified circuit, detecting circuit and alarming circuit is designed; then an improved on-line monitoring method is put forward and a system which can give alarm to add the printing ink while the ink in the ink fountain reaches the minimum position is developed. Lastly, the quantity of ink in the ink fountain can be displayed on-line and the new system using on-line monitoring method can realize the automation of inking-up in printing process. Experimental results in our laboratory show that this on-line monitor method can improve the automatic degree of most presses in our country, which will bring great economical and commercial benefits to our country's printing industry.
