1.Prevent rotary offset cigarette printing ink from thickening in cold weather
For ink, if the room temperature and the liquid temperature of the ink change greatly, the ink migration state will change, and the color tone will also change accordingly. At the same time, the low temperature weather will have a significant impact on the ink transfer rate of the high-gloss parts. Therefore, when cigarette box printing high-end products, it is necessary to control the temperature and humidity of the cigarette box printing workshop anyway. In addition, when using ink in winter, it should be preheated in advance to reduce the temperature change of the ink itself.
Note that the ink is too thick and viscous at low temperature, but it is best not to use thinner or varnish to adjust its viscosity. Because when the user needs to adjust the ink properties, the total amount of various additives that the original ink produced by the ink manufacturer is limited. If the limit is exceeded, even if it can be used, the basic performance of the ink will be weakened and the printing will be affected. Quality cigarette box printing techniques.
The thickening of ink caused by temperature can be solved by the following methods:
(1) Put the original ink on the radiator or next to the radiator, let it slowly heat up and gradually return to its original state.
(2) In case of emergency, you can use boiling water for external heating. The specific method is to pour boiling water into the basin, and then put the original barrel (box) of ink in the water, but prevent water vapor from immersing it. When the water temperature drops to about 27 degrees Celsius Take it out, open the lid and stir evenly before use. It is advisable to keep the temperature of the cigarette box printing workshop at around 27 degrees Celsius
