We often say that printing with the minimum amount of ink and the minimum amount of water in the printing process is actually to achieve and find a balance, that is, to restore the customer's original manuscript for the purpose of finding a printing ink balance. In the printing process, the absolute balance of ink and water does not exist, it is only a relative balance, and there is no clear boundary or reliable data to reflect, but there are rules to follow. To control the balance of ink and wash, it is necessary to ensure the specific conditions and state of the machine. The results show that the hardness of raw water should be 8 ~ 12dh, the pH value of the prepared fountain solution should be between 4.8 ~ 5.5, the conductivity should be controlled at 800 ~ 1800 microseconds, and the temperature of fountain solution should be controlled at 10 ~ 15 ℃. At the same time, printing operators should know that the temperature of the fountain solution is too low, which will cause condensation of water droplets in the water tank and pipeline, which will fall onto the printed matter during production, resulting in poor printing. Fountain solution to meet the above conditions can ensure that the ink balance can be found smoothly, otherwise it is easy to destroy the balance that has been achieved. Water, ink stick in the required hardness and pressure range to ensure the normal transmission of water and ink. The hardness of water and ink sticks can be used in the range of 24 ~ 28 ℃ and 28 ~ 34 ℃. The hardness of water and ink sticks will increase with the increase of service time, so it is necessary to check the hardness of water and ink sticks at regular intervals. At the same time, it is also necessary to ensure the normal pressure regulation of water and ink stick. The pressure of ink stick is determined according to the width of pressing line during adjustment, and the standard adjustment is carried out according to the characteristics of each printing machine and the factory requirements of printing equipment. The normal pressure of ink stick is about 3 ~ 4 mm, and the pressure of water stick is 6 ~ 8 mm. If the pressure is too high, the wear of water and ink stick will be increased, and the transmission of water and ink will be affected. Improper adjustment of printing is often one of the main reasons for the imbalance of ink and water. In normal adjustment, the water consumption and ink amount should be adjusted according to the ink amount of printing plate. However, many operators often just adjust the ink amount and ignore the adjustment of printing water consumption, especially when printing from a large amount of ink to a small amount of ink, which makes it difficult to achieve the balance of water and ink. In addition, a good printing environment is the premise to ensure good printing. The normal printing environment requires that the temperature should be controlled at 24 ~ 26 ℃, and the humidity should be controlled between 55% ~ 65%. This will be of great help to the transfer of ink and the control of water volume.
