一、易臟版
1、 Dirty version
夏天氣溫高,與其他季節相比,控水量應該適當增 大,這是應該加大上水輥的壓力;水量加大以避免臟版;2嚴格控制溫度;應該將印刷環境溫度控制在10-28度,溫度在15-25度,不要超過28度;如果條件允許。
The temperature is high in summer. Compared with other seasons, the water control volume should be appropriately increased, which is to increase the pressure of the water feeding roller; Increase the amount of water to avoid dirty version; 2. Strictly control the temperature; The printing ambient temperature should be controlled at 10-28 degrees, 15-25 degrees, not more than 28 degrees; If conditions permit.
在空調房間中進行印刷,以便控制溫度;實在沒有條件,也必須將機器挪到陰涼的地方去;3對濕度的控制;濕度與控水量是成反比例的;即濕度越大,控水量應減小;一般來說,膠印機適宜的環境濕度控制在相對濕度在50%-85%之間;
Printing in an air-conditioned room to control the temperature; There is really no condition, and the machine must be moved to a cool place; 3. Humidity control; Humidity is inversely proportional to water control; That is, the greater the humidity, the less the water control volume should be; Generally speaking, the suitable environmental humidity of offset press is controlled between 50% - 85% relative humidity;
二、油墨乳化
2、 Ink emulsification
夏天氣溫高,油墨變稀;此時,應該添加使墨變稠的0號調墨油;同時呢,考慮該項因素,控水量也應加大;2有些操作人員可能將油墨在冰箱中冰一下,這樣,由于溫度的降低使油墨變稠;但是。
In summer, the temperature is high and the ink becomes thin; At this time, No. 0 inking oil that thickens the ink should be added; 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; But.
由于在印刷過程中油墨的溫度會逐漸提高,因此,該種方法只是在短期內有用;3在選擇印刷油墨時,是挑選油性小一點的、適合夏天印刷的油墨;如果,油墨過稀,不妨加一點干燥油;實際在控水時,應該充分考慮墨的稀稠、溫度高低、濕度大小等綜合因素,以達到好的印刷效果。
Because the temperature of the ink will gradually increase during the printing process, this method is only useful in the short term; 3 when selecting printing ink, it is to select less oily ink suitable for summer printing; If the ink is too thin, you might as well add a little dry oil; In fact, when controlling water, we should fully consider the comprehensive factors such as ink thickness, temperature and humidity, so as to achieve good printing effect.
