Printing rubber roller selection:
With the rapid development of the market economy, new equipment, new processes, new materials, especially new printing equipment have also emerged. The replacement is also relatively timely, and the domestic printing equipment also tends to have high technology content, durability and advanced nature. From the perspective of the international printing industry, there are some data showing that some developed countries such as Europe and the United States still lead us in printing equipment. Although the domestic printing industry entered the printing machinery and printing equipment of many developed countries in the 1990s, when the printing rubber roller needs to be replaced for a certain period of time, the domestic printing rubber roller is far less than the rubber roller of the original equipment.
In the 1980s, there was a big revolution in printing rubber rollers. Rubber rollers were not restricted by climatic conditions and were strong and corrosion-resistant. However, the high cost made SMEs deterred. With the rapid development of the economy, it is still well received by the majority of users.
Storage and maintenance of rubber rollers:
In the past, printing companies have set up "glue rooms", which specialize in the production of printing rubber rollers, which are seriously polluted. With the development of the printing industry and the replacement of equipment, traditional old-fashioned printing rubber rollers have been gradually eliminated due to their inability to meet the needs of high-speed printing presses. Its shortcoming is that it can not adapt to high temperature and high humidity environment, softens at high temperature, and hardens at low temperature, especially for printing gold and printing screen, which hinders the improvement of printing quality.
Commissioning and proper use of the printing rubber roller: Regardless of any type of printing machine or model, after the new equipment is installed, the printing roller must be installed by the technician and the leader. The installation of the rubber roller must be properly tuned. It must be in close contact with the ink roller and the printing plate, and both are indispensable. The printing practitioners know that the height of the letterpress is 3.14mm, which is consistent with the height of the typeface, while the PS version is relatively low at 1.2mm, so be sure to know when installing and adjusting the rubber roller. If the printed product has a ground color, the rubber roller can be adjusted to a lower degree with an error of ±0.5 mm, so that the ink delivered to the printing roller by the ink roller is relatively uniform, and the printing rubber roller is also reflected on the printing plate. The effect is that the printed products are pleasing to the eye. If not, there will be phenomena such as ink sticks and ink paths.
Storage and maintenance of rubber rollers:
When printing text, the height of the rubber roller is basically flat or slightly lower than the text version, so that the printing rubber roller can gently rub the printing plate, so that the text is printed clearly and cleanly, and the rubber roller wear surface is small. Not easy to damage, can extend the life of the plate. The adjustment roller should be used for adjustment. Before use, remove the printing plate and let the adjusting roller horizontally extend and pull out several times. The size of the ink dot on the rubberizing roller will be displayed immediately. The operator can determine the level of the printing rubber roller according to different printing requirements, and then Put the top thread firmly. Thus, the height of the rubber roller does not change during high-speed printing. If we are impatient when using rubber rollers, and debugging is eager to save trouble, the following will happen:
(A) The surface of the rubber roller is damaged, and the slag is dropped, so that the text is printed and the pen is broken, the text is blurred, and even the phenomenon of paste and gel is observed.
(B) The text is different in ink, and even the surface of the printed product has only the text mark but no ink color.
(C) If the rubber roller is adjusted to be too tight with the transfer rubber roller, the printing rubber roller will be damaged to cause economic loss and equipment accident.
Maintenance of printing rubber rollers:
In the offset printing technology, the key is the control of the balance between the water path and the ink path, and the balance of the ink and ink depends on the key components of the rubber roller and the ink roller, and the quality of the ink can directly affect the product quality. This is especially true for gravure, embossing, and flexo printing. General printing companies maintain equipment once a week, including the maintenance of printing rollers. There are several ways to maintain:
1. After the production operation is completed every day, the rubber roller should be carefully cleaned and washed twice;
2. Cleaning the printing roller must use the specified chemical, such as industrial alcohol, and must not use corrosive solvents;
3. Remove the rubber roller during the holiday break to prevent deformation under pressure;
4. The protection of the surface of the printing rubber roller should be wrapped in newsprint and placed in a dark place.
