夏天印刷厂容易出现什么问题?

一、易脏版
1、 Dirty version
夏天气温高,与其他季节相比,控水量应该适当增 大,这是应该加大上水辊的压力;水量加大以避免脏版;2严格控制温度;应该将印刷环境温度控制在10-28度,温度在15-25度,不要超过28度;如果条件允许。
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.
在空调房间中进行印刷,以便控制温度;实在没有条件,也必须将机器挪到阴凉的地方去;3对湿度的控制;湿度与控水量是成反比例的;即湿度越大,控水量应减小;一般来说,胶印机适宜的环境湿度控制在相对湿度在50%-85%之间;
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
夏天气温高,油墨变稀;此时,应该添加使墨变稠的0号调墨油;同时呢,考虑该项因素,控水量也应加大;2有些操作人员可能将油墨在冰箱中冰一下,这样,由于温度的降低使油墨变稠;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.
由于在印刷过程中油墨的温度会逐渐提高,因此,该种方法只是在短期内有用;3在选择印刷油墨时,是挑选油性小一点的、适合夏天印刷的油墨;如果,油墨过稀,不妨加一点干燥油;实际在控水时,应该充分考虑墨的稀稠、温度高低、湿度大小等综合因素,以达到好的印刷效果。
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.
