There are at least four advantages to the standardized operation of the machine: first, the machine performance is stable, the failure rate is low; second, the product quality is reliable; third, the work efficiency is high; fourth, it helps to develop a rigorous work style, scientifically analyze and solve the problem. Effectively improve their technical level. Take the above-mentioned ink and water balance, whether it is possible to install and adjust the ink roller according to the specifications of the machine operation manual is the premise for controlling the balance of ink and water. If the pressure between the rollers is light and heavy, and the rubber roller bearings are poorly lubricated, it will inevitably make the water transfer and ink transfer unstable, which will aggravate the wear of the rubber roller mechanism and cause various faults. The machine must be advanced by high-quality people. Play a role. In our daily work, we generally pay more attention to scientific methods, from the small adjustment of the machine to the ink on the ink, the rubber wash, etc., we must find out some of the standardized operations and continue to sum up experience.
To ensure that the ink balance also requires normalized operation.
(1) fountain solution
First of all, the ratio of the fountain solution should strictly follow the supplier's recommendations. Some operators have found that the amount of dampening solution or isopropyl alcohol is increased after the product is dirty, which is often caused by more harm. Secondly, it is necessary to analyze the change law of the pH value and conductivity of the dampening solution, and the conductivity has a certain guiding significance. If the conductivity is too high, it indicates that there is more impurities in the water, and the dampening solution should be replaced. In addition, the water tanks, water pipes, etc. should be regularly cleaned to prevent the dampening solution or alcohol actually inhaled during the operation of the dampening system from being inconsistent with the preset settings, and misleading the operator to determine various faults.
(2) Ink roller
First, we must resolutely adjust the pressure between the rollers by the method of measuring the width of the ink bar according to the machine operation manual. If you do not take the ink and water balance seriously, you will not be able to talk about it. Secondly, the surface of the rubber ink roller should be cleaned and maintained frequently. It should not be crystallized and hardened, and should always maintain its good ink transfer and water transfer performance. In particular, the metering water roller and the plate water roller in the alcohol dampening system are more "squeezing", as long as there is a little scratching of the ink stain, etc., the quality of the product will be affected.
(3) Other factors
The correct lining, the ideal printing pressure, high-quality ink and paper, and the stable paper feeding of Feida are all important factors to ensure the balance of ink and water.
