Ink should exist indoors, at room temperature in the 5 ℃ -50 ℃ degrees Celsius. Use, the use of stirring bar to the ink in the bucket, stir well, measure the viscosity of the inverted ink tank. If the viscosity is too high or too low, you can add thinner or thickener to adjust. Printing process due to the evaporation of water, will lead to increased ink viscosity and PH value decreased, PH value should be controlled between 8.5-9.5, if beyond this range, PH stabilizer can be used to adjust to maintain the viscosity and PH value of the stability .
In general, the ink is very suitable for high-speed printing handbag printing, low-speed printing in the case of drying speed is too fast or poor printing results, can add a certain percentage of slow-drying agent. After printing the remaining ink should be collected back to the corresponding original barrel or the ink tank cover the lid to prepare for the next use, beware of water evaporation caused by ink surface conjunctiva, thickening or even dry. The ink remaining on the printing set after printing can be cleaned with a cleaning agent before it is completely dried.
