Problems and solutions of summer printing
1、 Easy to dirty version 1 summer temperature is high, compared with other seasons, water control should be appropriately increased, this is to increase the pressure of the water roller; water increase to avoid dirty version; 2. Strictly control the temperature; the printing environment temperature should be controlled at 10-28 degrees, the best temperature is 15-25 degrees, and it is better not to exceed 28 degrees; if conditions permit, it is better to print in an air-conditioned room in order to control the temperature; if there is no condition, the machine must be moved to a cool place; 1 1. In summer, the temperature is high, compared with other seasons, the water control should be appropriately increased, which is to increase the pressure of the water roller; water volume should be increased to avoid dirty version; 2. Strictly control the temperature; the printing environment temperature should be controlled at 10-28 degrees, the best temperature should be 15-25 degrees, preferably not more than 28 degrees; if conditions permit, it is better to print in an air-conditioned room in order to control the temperature; if there is no condition, the machine must be moved to a cool place; In general, the suitable environmental humidity of offset press should be controlled in the range of 50% - 85%; 2) ink emulsification; 2; 1. In summer, the temperature is high, and the ink becomes thinner; at this time, you should add No. 0 inking oil which makes the ink thicker; at the same time, considering this factor, the water control should also be increased; 2. Some operators may freeze the ink in the refrigerator, so that the ink thickens due to the decrease of temperature; however, since the temperature of the ink will gradually increase during the printing process, this method is only effective in the short term; 3 in the choice of printing ink, it is best to choose a little less oily, suitable for summer printing ink; if the ink is too thin, you might as well add a little dry oil; In fact, when controlling the water, we should fully consider the ink thickness, temperature, humidity and other comprehensive factors to achieve the best printing effect; third, electromagnet heating, plate pressure is insufficient; in summer, why electromagnet heating? The reasons are as follows: 1. The temperature is high; the heat dissipation effect is mainly caused by the temperature difference between the electromagnet and the surrounding environment; the smaller the temperature difference is, the less ideal the heat dissipation effect is; 2. The voltage is too low; the best power supply for offset press should be kept at 220 V / 50 Hz, especially the interference of surrounding electrical appliances; in summer, due to the extensive use of electrical equipment, the voltage is too low, which intensifies the load of electromagnet and causes heat generation; 3. The resistance of electromagnet tension spring is too large; the resistance of tension spring is too large, causing heating phenomenon; in view of the above situation, we suggest to use continuous (non ordinary household step-up) AC stabilized voltage power supply to improve the operation quality and prolong the service life of the machine; on the other hand, we are also stepping up the research and development of electromagnet with stronger magnetic force to effectively solve the problem of insufficient magnetic force The fruit will soon be on the market.
