Zhuo Shurong: The experience of the technical project of tap water offset printing system
The author at the beginning of Yunnan, China Red Printing Co., Ltd. was established in 2009 to enter the company, the captain post for offset printing machines so far. As an old employee who has worked in the offset printing machine for more than 20 years, the author always feels: "If you want to produce a first-class product, you must know the equipment you are operating. You must be familiar with the advantages and disadvantages of the equipment and have to deal with it. The ability to make basic mechanical failures."
Of course, this is not a one-off effort, and it requires constant research and hard work. In order to continuously improve the operation technology and capabilities of its equipment, the author has always insisted on operating the Heidelberg CD102 6+1 offset press purchased by the company in 2009. Because the device is now aging and often needs to deal with various faults, the author has accumulated a lot of experience in the operation process.
In September 2016, in order to further improve the production capacity of offset printing, our company introduced the “zero alcohol lithography system†(also known as “tap water offset printing systemâ€). I have the privilege to participate in the whole process of the system from field trips, installation tests to professional training, where I share some experiences with my peers.
Visit
During the visit, I was most impressed by the fact that when I visited the offset printing production site of Yunnan Qiaotong Packaging and Printing Co., Ltd., I first felt that there was no pungent smell of isopropyl alcohol in the entire offset printing workshop; Chatting very easily, there is no such thing as a busy and tense machine.
The author thinks: "God! These employees are too bold. Even if they have the best technology, if they don't keep an eye on the machine, it is easy to produce waste. Are they not afraid?"
After the author's own equipment is also installed with the tap offset printing system, it is clear that the offset printing operation can be very simple, and the advantages of the tap offset printing system can completely compensate for the defects of the old equipment with 20 years old, and the products produced. It can be compared with the products produced by another new equipment of our company.
Technical transformation and testing
Yunnan Zhuoyin Technology Co., Ltd. (hereinafter referred to as “Zhuyin Technologyâ€) completed the installation and commissioning of our company's tap water offset printing system in just one day, and then carried out a morning technical training for the machine personnel, which made the staff very I quickly mastered the operation skills and precautions of the tap offset printing system, and soon officially put into production.
Our company has tested the tap water offset printing system. The test version has 6 colors, namely black, cyan, magenta, yellow, special 1, and 2, and the test results are shown in the following figure. It can be seen that after using the tap water offset printing system, the ink is hardly destroyed, the color saturation in the field is better, the edge of the dot is relatively real, the dot gain is extremely low, and the color reproduction is very good.
